Model 26 Fire Station Dispatcher 8 025-9158L
General Introduction General The Model 26 Fire Station Dispatcher is the dispatch end of the Zetron Fire Station Alerting System. This system has been specifically designed to speed the dispatch of emergency vehicles, to aid in tracking their status, and to provide remote control and sense capability at each station. Typically, there are one or two Zetron Model 6 Transponders in every station.
Introduction Backwards Compatibility Since its initial release in the early part of the 1990s, the Model 6/Model 26 system has had a number of hardware and firmware updates take place. Some of these were due to components going out of production and others were due to changes in the firm ware to enhance customer satisfaction with the product performance. System purchased before July of 1999 and never upgraded may be utilizing software protocols that are no longer supported.
General Figure 1: Complete Layout of Maximum System Up to 3 AUX panels for each Master or Slave Unit Total of 4 panels per position, 60 buttons per panel Model 26 AUX Unit Model 26 AUX Unit Model 26 AUX Unit Model 26 Slave Unit Model 26 Slave Unit Model 26 Master Unit Each Model 26 Master or Slave unit is a dispatcher position. A total of 15 positions is possible.
Introduction Front Panel Description The front panel of a Model 26 consists of 10 columns of six buttons each for a total of 60 buttons for sending commands. Each button has two light-emitting diodes (LEDs) associated with it: one green and one red for indicating status. Figure 2: Model 26 Fire Station Dispatcher Front Panel Layout Buttons The Model 26 serves as a command sender and a status receiver. Each button, or combination of buttons, on its front panel represents a command.
Front Panel Expansion Front Panel Expansion Up to three expansion panels can be added to a Model 26 giving a total of 240 buttons and 480 LEDs. There may also be up to 15 different dispatch positions. Each position is operationally identical to the Master Position. Figure 1 shows the relationship of the various units in an expanded system. Communication Interface The Model 26 is designed to communicate with Model 6 Transponders via a voice band audio communications path.
Introduction In addition, the wire lines must have no AC power supply or DC voltage, such as battery voltage on a dial-up line, attached to them. A leased line (not dial-up) is a good example of the type of line required. A “star” network configuration is recommended where the wire line from each station transponder (Model 6) terminates at the dispatch center (Model 26).
Communication Interface Conventional Radio Interface Besides the 2-wire or 4-wire transmit and receive connection, the Model 26 provides an open drain Push-to-Talk (PTT) output signal for transmitter keying and a Carrier Operated Relay (COR) input for detecting channel availability. Figure 4 shows a typical interface. If the radio does not provide a COR output signal the Model 26 has an internal, adjustable threshold VOX circuit for detecting channel activity.
Introduction Specifications Parameters Description Buttons 60 momentary, high-reliability pushbutton switches per panel Indicators 2 LEDs (light emitting diodes), 1 red and 1 green LED associated with each button (total of 120 per panel) Expansion Up to 3 expansion panels of 60 buttons and LED pairs each may be added to a position. A total of 15 identical positions can be connected together Power Requirements 12 to 14 Vdc at 3.
Equipment Needed Equipment Needed • A second person is required for alignment between the Model 6 and Model 26. One person works at the dispatch side (M26) and the other in the remote station (M6). Having two people is the most efficient method of setting the RX and TX FFSK levels. • A multimeter is required for measuring voltage. • A PC or laptop with a terminal program and a serial port.
Introduction 18 025-9158L
Hardware Jumper Settings Installation This section contains installation and service information. Each jumper, potentiometer, connector, and software configurable parameter of the Model 26 is discussed in this section. By starting at the beginning of this section and moving through it sequentially, the Model 26 should be completely installed and configured at the conclusion of the section. This section is also intended as a reference for many settings and adjustments of the Model 26.
Installation JP1 (RAM SELECT) This jumper selects the size of the on board RAM. There are three choices: Position A = 32K RAM Position B = 8K RAM No Jumper = 8K RAM All Model 26s use 32K RAM. This jumper should always be in the A position. JP2 (FFSK RCV SELECT) This jumper enables/disables the automatic gain control (AGC) circuit for FFSK signals.
Hardware Jumper Settings JP6 (MODEL 26 CHAIN TERMINATION) JP6 selects the termination resistance for the “CHAIN” interfaces. The “CHAIN” interface is used to link together multiple dispatch positions. There are three positions for this jumper: Position A = Unterminated CHAIN Interface Position B = Terminated CHAIN Interface No jumper = Same as the Unterminated position All positions except one should be unterminated (A).
Installation JP9 (4 WIRE RCV IMPEDANCE) This jumper selects the impedance of the 4-wire receive audio input. There are three positions for this jumper: Position A = Selects 600Ω Position B = Selects 10 kΩ No jumper = Selects 10 kΩ JP9 should be in the A position (600Ω) if there is only a single Model 26 in the system.
Option Switch Settings JP12 (RS232 RXD FUNCTION) JP12 selects the routing of the Received Data at J7, the serial interface connector for the CAD/Printer port. There are three positions for this jumper: Position A = Selects Pin 2 as RxD input (configured as null-modem connection). Position B = Selects Pin 4 as RxD input (typical Zetron 3-wire connection). No jumper = Selects no Received data (JP12 must be in either A or B).

Installation These modular, 4-conductor connectors are located on the right side of the rear panel (see Figure 6). They are used to connect up to three expansion panels to the Model 26. These are unidirectional ports: the LOOP OUT port transmits; the LOOP IN port receives; and they must always be connected with a half twist cable, even if no expansion panels are used.
Electrical Connections These ports have voltage and current levels which are RS-232 compatible. The following are the pin descriptions for these two connectors: Pin/Signal Description OUT-1 (GND) Connected to Model 26’s chassis ground. OUT-2 (TX) This is an output and carries the data being transmitted. OUT-3 (+12VDC) This carries power to the expansion panels. OUT-4 (GND) Connected to Model 26’s chassis ground. IN-1 (GND) Connected to Model 26’s chassis ground.
Installation Pin/Signal Description OUT-1&2 (GND) Connected to Model 26 chassis ground. OUT-3 (RXD) This is an input and carries the data being received. It is also connected to IN-4. OUT-4 (TXD) This is an output and carries the data being transmitted. It is also connected to IN-3. OUT-5&6 (GND) Connected to Model 26 chassis ground. IN-1&2 (GND) Connected to Model 26 chassis ground. IN-3 (TXD) This is an output and carries the data being transmitted. It is also connected to OUT-4.
Electrical Connections J13 Connector This connector is the inside connector of the two on the left side of the rear panel. The following are the pin descriptions: Pin Description 1 (XBUSY+) This input, when driven low, prevents the Model 26 from beginning to transmit. It is typically connected to a XBUSY output from a console, to prevent the Model 26 from sending data packets while a voice dispatch in being made on the channel. 2 (XBUSY-) This is connected to the chassis ground of the Model 26.
Installation Pin Description 8 (PA READY) This signal is used to signal a dispatch console when it is time for the dispatcher to talk through the remote station’s PAs. This is an open collector output. Its active state polarity is set in the Software Configuration Program by the “PA Ready Active Polarity” parameter (see System Configuration Menu on page 33). It is typically connected to the XBUSY or BUSY MUTE input on a dispatch console to mute unwanted noise.
Electrical Connections CAD/PRINTER Connector This port has three different functions based on the port configuration in the Serial Port Configuration menu (see Software Configuration Program) and the position of OPTION SWITCH-7. If OPTION SWITCH-7 is in the On position, then this port is used to access the Software Configuration Program with an RS-232 terminal.
Installation Software Configuration Program Before the final hardware adjustments can be made, several parameters in the software that operates the Model 26 must be configured. This is done with the Software Configuration Program. To access the Software Configuration Program, connect an RS232 terminal (or a computer running a terminal emulator program) to the CAD/PRINTER port on the back panel of the Model 26 using the Zetron programming cable (Zetron Part No. 709-7211).
Software Configuration Program The very first line displayed, while in this program, shows the name of the current menu and the current address setting for the Model 26. Each Model 26 must have a unique address and the primary Model 26 must be address number one. This address is set by the first four switches on the OPTION SWITCH. The Software Configuration Program is not case sensitive. Either upper or lower case characters can be used and the results are the same.
Installation Figure 10: System Configuration Menu Communication Mode This is the first parameter listed in the System Configuration menu. It holds the Communication Mode that the Model 26 is currently operating under and this in turn effects which parameters are displayed in the System Configuration Menu. When this parameter is selected the menu in Figure 11 is displayed showing the operating modes that can be selected for the Model 26.
Software Configuration Program Note The COR/VOX LED can be used to track the current state of the COR input to the Model 26 (J13-pin 5); however, you must always remember that the LED being lit only means that the input has been pulled low. If option 3 in the Communication Mode menu is selected, then TX is Enabled while the LED is lit. If option 4 in the same menu is selected, then TX is Enabled when the LED is not lit.
Installation Figure 12: Wire Line System Configuration Menu The reason this mode must be used on “star” network wire line systems is because Model 6s cannot hear other Model 6s when they transmit, only the Model 26. In all other communications modes the Model 6s may transmit unsolicited. When using these other modes, they listen to see if the line is clear to prevent transmit collisions.
Software Configuration Program Figure 13: VOX Mode System Configuration Menu Conventional Radio - TX on COR Communication Modes There are two different COR communications modes, “COR, Tx on COR High” and “COR, Tx on COR Low”. (See Figure 11) These two communications modes are designed for operation with a conventional radio interface where the Model 26 uses the radio’s COR signal to detect channel availability.
Installation Figure 14: COR Mode System Configuration Menu Trunking Communication Modes There are two different trunking communications modes, “Trunking, Chan Grant on High COR” and “Trunking, Chan Grant on Low COR”. (See Figure 11) These two communications modes are designed for operating with a trunked radio system that can provide a channel grant signal to the Model 26. Like the COR communications modes, the different trunking modes are based on the logic state of the channel’s active grant signal.
Software Configuration Program Figure 15: Trunking Mode System Configuration Menu Note The use of Model 6 and Model 26 equipment for data transmission with a trunked radio system raises a number of technical issues that are typically not encountered with wire line or conventional radio equipment. In general, trunked radio systems introduce longer delays on the initial transmission of an alert than a conventional radio.
Installation • Designated Stations = this is basically the number of stations to be polled during a given polling cycle, it is set with the Stations per Poll Time parameter This parameter sets the time between polling cycles. It works in conjunction with the Stations Per Poll Time parameter (discussed in the following sub-section) to control the polling speed of the Model 26. It can have a minimum value of zero (0) and a maximum value of 9:59:59.99 (9 hours, 59 minutes, 59 seconds and 990 milliseconds).
Software Configuration Program Stations per Poll Time Note The parameters Poll Time and Stations per Poll Time appear in all communications modes except for Wire line. This parameter is found on all System Configuration Menus except for Wire Line communications mode, where it is fixed at zero. This parameter holds the number of stations polled during each polling cycle. If it is set to zero then all stations are polled during every polling cycle.
Installation delay occurs at the beginning of each transmission, this parameter should be as small as possible to maximize system performance. The Data Mute line is also asserted at the beginning of this delay. If the console cannot mute fast enough to block FFSK packet noise, the value of this parameter can be increased to provide more time. Increasing the value of this parameter slows down the response time of the entire system.
Software Configuration Program Retry Period This parameter is found in the System Configuration Menu. It holds the time interval, in seconds, for which the Model 26 waits for a reply after polling a Model 6. The Model 26 will do 4 retries before posting a communications error for the Model 6. This parameter should be as short as possible to minimize system delays whenever retries occur. However, it still must be long enough so that the Model 6 has time to respond.
Installation PA Ready Active Polarity This parameter is found in the System Configuration Menu. It is used to set the active polarity of the PA Ready (J13-8) output signal. When this parameter is set to “High,” the PA Ready signal goes high whenever a PA ready state exists; otherwise, it is low. Selecting this parameter toggles it between “Low” and “High” settings. Trunking Grant Debounce This parameter is found in the System Configuration Menu.
Software Configuration Program Normally the Model 26 polls the Model 6 to verify the receipt of the text. By setting this option to NO, the Model 26 will not poll the Model 6s, which reduces the overall system time requirement for the text command. Rekey Minimum Time This value is the minimum delay time from PTT going inactive on one transmission until the Model 26 is allowed to transmit another message to a Model 6.
Installation Figure 16: PA Configuration Menu Wait for Dispatcher Timeout This parameter is found in the PA Configuration Menu. It holds the maximum period of time, in seconds, that the Model 26 will wait for the dispatcher to keyup after all the Model 6 PAs are ready. If this parameter times-out before the dispatcher’s microphone is keyed, the Model 26 will send a PA OFF command to all Model 6s. This parameter accepts a value between 0 and 99 seconds. A typical time-out value would be 10 to 15 seconds.
Software Configuration Program There are two different Port Configuration menus, one for CAD and the other for Data Logging. The menu that is displayed depends on which port function is currently selected. The current setting is displayed next to option {1}. The setting can be changed by selecting menu option {1}, which toggles between these two menus. The Data Logging Menu appears in Figure 17, and the CAD Menu appears in Figure 18.
Installation Baud Rates This parameter is found in the Port Configuration Menu in both the CAD mode and the Data Logger mode. When this menu item is selected it displays the menu in Figure 19 to select the baud rate for the CAD/PRINTER port. This baud rate selection does not affect the baud rate of the Terminal Configuration Program. Sense Inputs Log This parameter is found in the Port Configuration Menu when Data Logger Mode is the selected mode of operation for the CAD/PRINTER port (see Figure 17).
Software Configuration Program Figure 18: CAD Menu Change to Data Logger Mode This parameter is found in the Port Configuration Menu when CAD Mode is the current mode of operation for the CAD/Printer port (see Figure 18). Selecting this parameter places the Model 26 in DATA LOGGER mode (as soon as OPTION SWITCH-7 is placed back into the “OFF” position) and displays the menu parameters associated with DATA LOGGER.
Installation Figure 19: CAD/PRINTER Baud Rate Select Menu CAD Retry Timeout This parameter is found in the Serial Port Configuration Menu when CAD is the selected mode of operation for the CAD/PRINTER port (see Figure 18). It holds the CAD interface transmit retry timeout value. This is the time interval that the Model 26 waits for a response, on the CAD interface, after sending a CAD data packet. If no response is received during this time interval, the Model 26 resends the data packet.
Software Configuration Program Figure 20: Beeper Configuration Menu Each beep type has a number of configurable parameters so the events associated with the audible prompt can have a distinct sound or the prompt can be disabled completely. Not all beeps produced by the Model 26 are configurable. All the configurable beep prompts are displayed on this menu. Power Up This beep type occurs whenever there is a reset of the Model 26.
Installation Model 6 Sense Input This beep occurs whenever the sense input on a Model 6 becomes active. This beep is heard at the master Model 26 only. When one of the beep types is selected for configuration, the menu in Figure 21 is displayed so its parameters can be altered. Figure 21: Power-Up Beep Parameters Menu Beep Volume This parameter sets the volume level of the selected beep. It accepts a value between 0 and 9 (zero does not mean off).
Software Configuration Program Beep Off Time This parameter holds the number of 50 millisecond time intervals used to set the interval between beeps in the selected beep prompt. It accepts a value between 1 and 15. Test Beep Selecting this item from the Beep Parameters Menu plays the selected beep based on its current parameters. Clock Setting Menu This menu is selected from the Main menu by pressing the “5” key and displays the menu for setting the date and time.
Installation Figure 23: Reset to Defaults Confirmation Prompt Pressing Y will reprogram all configurable parameters to their factory default values (see Appendix A: Programmable Settings and Defaults for a complete listing of the factory default values). Pressing N will exit this selection without reprogramming any parameters. FFSK Test Menu This item is found on the Main menu. When this menu item is selected, the menu in Figure 24 is displayed for selecting Model 26 testing tools.
Software Configuration Program Generate FFSK Test Tone This item is found on the FFSK Testing menu. It is used to produce a FFSK test tone for adjusting output and receive levels on the Model 26 and Model 6. When this item is selected the following message is displayed: Generating 30 Sec. FFSK test tone for level adjustment. Press ANY key to end test sooner. When this message is displayed the Model 26 is transmitting a FFSK test tone.
Installation Figure 25: Software Information Supplied by “ABOUT” In the example shown here, 3.22 is the software version number and 1.04 is the customer version number. Adjustments There are a number of adjustable potentiometers (pots) on the back panel of the Model 26. Some of these pots must be adjusted before the Model 26 can transmit and receive properly. The order in which the adjustments are made is important.
Adjustments finished. Also, there can only be one unit for each address, otherwise conflicts will occur. While adjusting secondary units either the primary unit must be taken Off Line or its address changed. Tip Please see Appendix D (starting on page 109) for a more detailed procedure for adjusting FFSK transmit and receive levels between the Model 26 and the Model 6. Figure 26: Model 26 Rear Panel Level Controls FFSK XMIT This potentiometer adjusts the output level of the FFSK transmissions.
Installation mode, measuring across the Rx inputs of the Model 6 while the Model 26 is transmitting an FFSK test tone. (See Appendix D starting on page 109.) The Model 26 FFSK output level for a radio communication interface should be set to the radio manufacturers specification. It is normally recommended that the data signal produce a 2.5 kHz deviation for wide band and 1.5 kHz for narrow band on FM or PM type transmitters. Use JP10 to aid in obtaining the correct signal level.
Adjustments radio and should be adjusted so background noise is not detected (COR/VOX LED off). The COR/VOX LED should be off when the channel is idle, but should be on when the channel is busy (voice traffic or tones). MIC XMIT This pot adjusts the HANDSET mic level. This level affects both the audio level transmitted to the Model 6s and the feedback level heard in the Model 26’s HANDSET ear. If this pot is adjusted completely counterclockwise HANDSET mic audio will be muted. Adjust this pot as required.

Introduction CAD Interface Installation Introduction This chapter begins with a summary of the connection of a CAD processor to the Model 26 and the programming of the Model 26 to prepare for CAD commands and responses. The summary is followed by a description of the protocol and the data level which describes the data content of each packet. Setup Summary ♦ To set up the connection between the CAD processor and the Model 26: 1.
CAD Interface Installation 3. Press the space bar on the terminal three times and the Main Menu will appear. 4. From the Main Menu, select the Port Configuration menu and make the appropriate selections to produce the following port configuration: Key CAD Parameters Current Settings {1} Change to Data Logger Mode: CAD Mode {2} baud Rate: 9600 {3} CAD Retry Time-out: 2.00 (Sec.Hun) {E}xit 5.
Protocol Level Data Packet Data packets are packets with bytes embedded in the middle between the STX and the ETX. Data packets from the CAD are called Command Data Packets, while data packets from the Model 26 are called Response Data Packets.
CAD Interface Installation Response Data Packets (From Model 26) The three Response Data Packets are Station Partial Status (03), Station Input (Alarm) Status (0A), and Station Full Status (0C). Byte Hex 1 2 3 4 5 to n n+1 n+2 STX LLSEQ# HLSEQ# RESP# DATA BYTES ETX CHKSUM 02 00 or FF 00 to FF 03,0A,0C See Note 1 03 00 to FF Note 1: See Text - A Special Case on page 68 Response Text Packet (From Model 26) The Response Text Packet is Text Flow Control (0D).
Protocol Level Sequence Numbers, Escapes, and Checksums Low Level Sequence Numbers (LLSEQ#) The low level sequence number is one byte which is either 00 or FF hex. The Low Level Sequence numbers are alternated between 00 and FF for each new packet sent. If a packet needs to be resent because of an error, the same low level sequence number is used. When a packet is received correctly, a Low Level ACK is returned with the same sequence number as the received packet.
CAD Interface Installation Note In order for CAD to generate a checksum, it must add all of the bytes after the STX up to but not including the ETX. The resulting least significant eight bits is then complemented, one is added and this checksum is placed at the end of the message. This results in a CKSUM value, when added to the sum of the Low Level Sequence number and all the data bytes between STX and ETX, modulo 256, will equal zero.
Protocol Level CAD Command with Retry When CAD sends a packet which does not change the state of the Model 6 or any of its units, such as a request for the status of a certain station transponder, the following sequence takes place. If the Model 26 does not respond immediately with an LLACK, the CAD will re-transmit the request. If the Model 26 responds with an LLACK and the wrong LLSEQ#, the CAD will re-transmit the request.
CAD Interface Installation CAD Command Station Relay Control When the CAD wants to energize a relay at one of the stations, the following exchange takes place. Note that the status of the relays is NOT returned.
Data Level Packet Details A synopsis of the total exchange is described below, which is not inclusive nor does it include all the variations that are possible with text commands.

CAD Interface Installation 82 025-9158L
Start-Up Operating the Model 26 Start-Up When the Model 26 is powered-up, it initializes all RAM memory locations to zero and checks the integrity of the Software Configuration Program parameters stored in the microprocessor’s internal EEPROM. In the unlikely event the integrity of these parameters has been compromised, the Model 26 will attempt to replace them with Factory Default Values. If the Model 26 succeeds in reprogramming the EEPROM, it will send the following message out the CAD/PRINTER port.
Operating the Model 26 Polling During inactivity the Model 26 polls each Model 6 at the rate set in the Poll Time parameter (refer to Poll Time on page 39). As mentioned in the programming section, there are two philosophies on polling speed, depending on the communication medium used between the Model 26 and the Model 6s. If the medium is wire line, then it is best to poll as often and as quickly as possible.
Sending Model 6 Commands Sending Model 6 Commands The buttons on the front panel of the Model 26 are used to send commands to the Model 6 (refer to Front Panel LEDs on page 92). Pressing one of these buttons, or a combination of buttons, causes the Model 26 to immediately send the command selected to a Model 6, or a group of Model 6s. After a Model 6 receives a command, it acts on the command and returns its new status to the Model 26.
Operating the Model 26 ON AIR This command changes a unit’s status to “Available On Air”, at a Model 6. This status typically indicates that a unit is not at its quarters, but is still available for service. There are no buttons representing this command on the Model 6, and unit buttons for this command are not normally found on the Model 26. This unit command is more efficiently handled by a system button using the same command. RSPND This command changes a unit’s status to “Responding”, at a Model 6.
Sending Model 6 Commands COND SERVICE This command changes a unit’s status to “Conditionally Out Of Service”, at a Model 6. This status typically indicates the unit is not available for normal use, but that it has limited capability. This command can be initiated at the Model 6 when a unit’s “QRTRS/AIR” and “OUT SERVICE” buttons are pressed simultaneously. Unit buttons for this command are not normally found on the Model 26.
Operating the Model 26 UNIT ALERT WITHOUT PA This command changes a unit’s status to “Alert” at a Model 6, but does not enable the PA system at the station. There are no buttons representing this command on the Model 6. This command might be used instead of the “Unit Alert With PA” command if the Model 6 is not being used to control the station’s PA system. UNIT ALERT OFF This command changes a unit’s status to “Not Alerted” at a Model 6, and turns off the station’s PA.
Sending Model 6 Commands Every station in the system should have at least one station button on the Model 26 so their station status can be displayed and their station address used by system buttons. Usually this button would be a “Station Alert” button. All other station commands are more efficiently handled (space wise) by system buttons. Each station command that can be associated with a station button or system button is discussed in the following paragraphs.
Operating the Model 26 PA ON This command turns on a station PA for announcements from the dispatcher. Once the Model 26 receives the PA ON status from the Model 6, the dispatcher may key the microphone at the Model 26 and speak. If the time period for the Wait for Dispatcher Time-out expires (refer to Wait for Dispatcher Timeout on page 46) before the microphone is keyed, the Model 26 sends a PA OFF command to the Model 6.
LEDs DAY/NIGHT MODE TOGGLE This command sends a PA On command to all stations, puts the Model 26 in the Day mode (PA On), and turns both LEDs on. If the button is pressed again, it returns the PA systems to the Normal or Night mode (PA Normal), until the button is pressed again. The system continues to poll the stations while in the Day mode, but the PA systems at the stations are available to the dispatcher for making announcements simply by keying the mic.
Operating the Model 26 Front Panel LEDs There is a pair of LEDs, one green and one red, associated with each button on the front panel of a Model 26. These LEDs are used to indicate different unit, station and or button conditions depending on their states. The LED function is programmed at the factory as defined by the customer. Each LED can assume one of the following states: Off On (continuously) Blinking Thus, a pair of LEDs can represent one of nine different states.
LEDs STATION LEDS Station LEDs are associated with station buttons and indicate station status. The LED states used to represent the status of individual stations are specified by the customer when the system is ordered. The factory default LED states are shown in the following table.
Operating the Model 26 programmed to show input status. Sense inputs can have only two states, active or inactive. One LED pair can display the status of two sense inputs. The LED combinations used by the Model 26 to indicate the current state of sense inputs are selected by the customer when the system is ordered. Back Panel LEDs There are two LEDs on the back panel of the Model 26: COR/VOX and PTT. These two LEDs deal with Model 6 communications.
Alert with PA Commands Trunking Grant Debounce time period has expired), the Model 26 thinks a channel has been granted and it can transmit. If this LED is on and under these conditions, the Model 26 thinks a channel has not been granted and it will not transmit. If this LED is on, then the Model 26 is receiving a logic low signal on its RX COR+ input.
Operating the Model 26 status is a higher priority status than an Alert status, the PA On status becomes the status displayed on the station’s LED pair. Once the PAs in all the alerted stations are on, the Model 26 enables its handset microphone and waits for the dispatcher to key the microphone to make any announcements. It also switches its PA READY output to a logic low (or a logic high, dependant on its configuration) to signal a console that the PAs are available.
Data Logging Data Logging The Model 26 has the capability to send a time stamped record of its activities to a serial printer, for permanent record keeping. This capability is not available when a CAD system is connected to the Model 26 because they both must use the same port (CAD/PRINTER port). This feature is only available on the primary Model 26, not on any secondary units. To enable this feature, first access the Software Configuration Program. Set the port mode to “Data Log”.
Operating the Model 26 system, and Model 6 status will be displayed on both. See Model 26 Fire Station Dispatcher CAD Interface Specification (part number 027-0059) for a description of the CAD protocol used between the CAD and the Model 26.

Equipment for these Procedures Appendix D: Setting Model 6 and Model 26 Audio Levels This procedures presented here will guide you quickly through setting the receive and transmit FFSK levels for a typical Model 26/Model 6 Fire Alerting system. In an effort to promote clarity, the level setting procedures are presented in two formats. The first version is written for a radio-based system. The second version is written for a wire linebased system.

Hit the SPACE bar three times to open the Model 26 Main menu. 2. Enter a “7” to open the FFSK Test Menu. 3.
Setting FFSK Levels in a Radio-based System Note In a radio system, the volume of the receiving radio may have to be adjusted. Ideally, the FFSK signal should cause 2-3 kHz of deviation in FM type radios. However, the significant parameter is the voltage at the receiving entity’s input terminals for a continuous FFSK signal generated by the transmitter in the Test Mode. Most radios have more than enough receive gain to accommodate this requirement.

Overview Appendix F: General Troubleshooting Guide Overview This section provides some suggestions useful in troubleshooting situations that may occur with the installation or operation of the Model 6 / Model 26 system. For further help, please contact Zetron at (425) 820-6363, and ask for Technical Support on the Model 6 or Model 26 equipment. Problem: Upon power up of the Model 26, no LEDs light and no beeps are heard.
Appendix F: General Troubleshooting Guide is the Master, verify that its address via the rear dip switches are set to “1”. If this Model 26 is a Slave, verify the Multiple Model 26 Chain connection on the rear of the Model 26(s) is good. This indication may also occur if the Model 26 is programmed to recognize secondary Model 6s but they have not been installed yet. Problem: When attempting to program Model 26 or Model 6, unable to get the Main Menu to display on PC. Solution: Verify cable pin-outs.
Overview Problem: Upon power up of Model 6, no LEDs light. Solution: Check Model 6 power supply cable, and internal fuse, F1. When the Model 6 is powered on, the LEDs should go through a self-test. First, the LEDs flash a vertical pattern, then a horizontal pattern. At this point with the Model 6 in an idle situation, only the vehicle status LEDs should be lit. If an EPROM was recently installed in the Model 6, verify correct placement of EPROM in socket.
Appendix F: General Troubleshooting Guide increasing the keyup delays for the radio equipment may help prevent retries from taking place. If no communication failures or retries are occurring, try decreasing both units’ keyup delays, as well as the voice debounce time (Model 26 only) to aid efficiency. Due to the external equipment the Model 6/26 system interfaces to, especially in a radio environment, it generally requires analyzing and adjustments to determine how efficient the Model 6/26 system will be.
