Safety Section D9124 and High Voltage The D9124 System connects directly to a 20 Amp, single phase circuit breaker. The high voltages at these connections are extremely dangerous. Only licensed electricians should make or service these connections. Ground the System First All connections to the 120 VAC terminals should be performed as directed by NEC 70.
Introduction Protective Points As shipped, the Radionics D9124 Addressable 24 VDC System provides eight on-board points built into the panel. On-board points 7 and 8 support a 24 volt power supply and notification circuits, and are not for other uses. As shipped, the panel can support 63 added POPITs. In addition, if you use an additional D8125 POPEX Module, another 63 points can be added, for a maximum total of 134 (8+63+63).
Skeds (scheduled events) The Skeds feature of the D9124 System uses the panel’s internal clock and calendar. Each Sked is programmed for a time, and either a day of the week schedule or a date of the year schedule. The user can change the time a Sked occurs if it is programmed for time editing. For example, the D9124 System can use the Skeds for a service reminder feature. In this application, a system fault that activates the panel trouble sounder can be acknowledged and the sounder silenced.
Installation D9124 Assembly System Components The D9124 Addressable 24 VDC System ships in three separate packages. The D9112LTB Control/Communicator comes in one package; the D9101 enclosure comes in another package; the D9100 accessory module carrier, a D1601 transformer, the transformer enclosure and literature ship in a third package.

Connect additional modules (except for D8125 POPEX Modules) to the D9124 System as shown in Table 2. Refer to the module’s installation instructions for remote device wiring instructions. Table 2 shows only connections to the D9124 System. Route cables above the D9100 Accessory Module Carrier to locations on the D9112LTB.
Command Centers and Annunciation Devices Descriptions D1255 and D1255R Command Centers The D1255 Command Center is a digital system control station with a 16-character alphanumeric display. It provides system control for the D9124 System. Housed in white plastic, it displays text identifying specific initiating and supervisory devices.
Maximum number of command centers: You can connect up to eight supervised or 32 unsupervised command centers to the D9124 System. The available power, number of supervised command centers, and number of areas you intend to use affect the total number of command centers you can connect to the D9124 System. Installing Command Centers and Annunicators A four-wire flying lead is required for the data and power connections between the D1255, D1255R, D1256, D1257 and the motherboard.
8. Connect the flying leads of the wiring assembly (provided) to the wires from the panel, as shown in Table 4.
Indicating Circuit (24 VDC Horns, Strobes, Bells) Description The D192C Indicating Circuit Module supervises the wiring from the control/communicator to remote alarm indicating devices like horns, strobes, and bells. Wiring is supervised for open, shorted, or grounded circuit faults.
ZONEX, Addressable Points Description You can use POPIT (Point of Protection Input Transponder) modules to provide up to 126 off-board points, bringing the total number of points the D9124 system can monitor to 134. Each off-board point requires a POPIT module. POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises (see Figure 14). Data expansion loops connect to the motherboard. The motherboard connects to the POPEX module.
With an Additional D8125 POPEX Module: • You can use D8125 POPEX 2, data loops 5 to 8 (terminals 19 to 26) on the motherboard. • You can install an additional 63 POPITs (points 73 to 135) for a maximum of 126 POPITs in the system. Connecting the Additional D8125 Module 1. Mount the module to a D138 Mounting Bracket, only using the three screws provided. 2. Mount this assembly in the empty slot next to the other modules on the accessory module carrier. Use the orientation of the other modules as a guide.
D9112 Program Record Training Sheet for the D9124 System The D9112 Program Record Training Sheet for the D9124 (74-06802-000) presents an example of a completed program record sheet for the D9124 System. The first column on the program record sheet contains the address settings for the POPITs. Addresses are numbered 1 to 6, left to right. Set addresses whose number appears in the ON position. Set addresses with a dash (-) in the OFF position (see Figure 12).
Wire Gauge Ohms per 1000 ft. 12 1.62 14 2.58 16 4.09 18 6.51 20 10.40 22 16.50 Table 6: Resistance by Wire Gauge Regardless of wire gauge or distance used, total resistance of the D8125 POPEX Data Loops cannot exceed 60 Ω. To determine total resistance, tie the ends of the D8125 POPEX Data Loops together to eliminate POPIT resistance (see Figure 12). After measuring resistance, untie the ends of the D8125 POPEX Data Loops.
Connect POPITS to the Data Cable You do not need to wire POPIT modules in any order on the motherboard’s D8125 POPEX Data Expansion Loop. An address setting on each POPIT (see Selecting POPIT Point Assignments) identifies the point of protection, regardless of its physical location on the data cable. POPIT modules must be mounted at least three inches apart. This prevents the tamper magnets from interfering with each other. Connect POPIT modules to the data loop in parallel.
Connecting Data Loops to Terminals on the Motherboard D8125 POPEX modules must have their own data expansion loops: The motherboard provides two sets of D8125 POPEX Data Loops. POPIT modules assigned to D8125 POPEX #1 cannot be placed on the D8125 POPEX #2 Data Loop. Limit the Data Loops coming back to the motherboard to a maximum of four data loop runs for each POPEX you install.
POPIT Displays For a list of D1255, D1256, and D1257 displays, refer to the user’s guide provided with the command center or fire alarm annunciator. Central Station Reports A complete list of reports received by the D6500 Receiver can be found in the D6500 Security Receiver Computer Interface Installation Manual (74-05313-000) and the D6500 Report Directory (74-04651-001). Reports from the D9124 System are the same as those generated by the D9112.
Power Supply Power for the D9112LTB, Command Center and Modules Primary Power The D9112LTB receives 16.5 VAC 40 VA transformer power from connector J9 on the D9142 Power supply. For information about installing the D1601 Transformer, see Installing the D1601 Transformer in the Installation section. Secondary Power One or two D126 12V, 7Ah or D1218 12V, 17.2Ah sealed lead-acid rechargeable batteries supply the power for the control/communicator, command centers, and the modules.
Installing the 12V Standby Source Batteries Connect batteries in parallel. Two batteries are required. Before handling batteries, see the Safety Section for important information. 1. Place the batteries on the bottom shelf. The longer set of leads from the battery harness (see Figure 16) connects to the battery on the right side of the battery shelf. 2. Connect the black negative wires from the battery harness to the negative terminals on the batteries. 3.
Battery Lead Supervision The 12 V battery leads are supervised. Battery Charging Circuit Float Voltage The float voltage for the 12 V battery charging circuit is 13.9 VDC at a maximum current of 1.4 Amps. Deduct any continuous load for 12 V devices connected to the panel from 1.4 Amps to find the actual current available for charging. Load Shed Relay protects battery: During an AC power loss the battery supplies extended power to the security system. If the battery voltage falls below 10.
Choosing the Right Batteries to Meet 24V Requirements The correct size of batteries connected to the system depends on the amount of current that devices draw from the power supply and the standard that you are meeting. See the Auxiliary Current and Standby Battery Requirements section, Calculations for 24 VDC Devices for more information.
D9142 24 VDC Power Supervision When the float charge drops to a low battery condition, or when the batteries are removed, the red LED on the power supply illuminates. The D9142 sends a TBL POINT 8 report to the receiver, Point 8 displays a trouble at the command center. Investigate low battery reports immediately. Battery Float Voltage The float charge voltage for the battery charging circuit is 27.6 VDC. Circuit Protection The power supply limits current output to 4 Amps.
Power Output Auxiliary Power Outputs All external connections at the D9124 motherboard are Power Limited. 12V Auxiliary Power from D9112LTB Terminal 1 The D9124 supplies 1.4 Amps at 10.2 to 14 VDC to power auxiliary devices. A selfresetting circuit breaker protects the circuit against shorts. Devices powered from this output must operate within a range of 10.2 to 14 VDC.
Alarm Power Output for Indicating Circuits 24 VDC Output Terminals 7 and 9 Each Alarm power output terminal (7 and 9) on the motherboard provides 24 VDC, 1.8 Amps maximum of alarm power output for bells, sirens, piezo fire sounders, and electronic horns and strobes. Current calculations in Table 10 are based on a 3 Amp maximum.

Telephone Connections D928 Dual Phone Line Switcher You must use two phone lines for a reporting fire system to meet UL and NFPA standards. Description The D9124 uses the D928 to transmit reports over a second phone line. The D928 allows the D9124 to monitor both the primary and secondary phone lines. For information about connecting the D928 to the D9124, see Connecting Cables Between D9124 System Components in the Installation section of this manual.
The D928 uses the primary phone line to dial a primary, backup, or duplicate phone number. The D9124 switches to the secondary line only when the D9124 senses trouble on the primary telephone line. During primary telephone line failure, the D9124 transmits all messages on the secondary line. When the primary telephone line trouble clears, the D9124 sends the restoral message to the receiver on the primary telephone line. All messages are again sent on the primary line.
Phone Line Failure LEDs Two yellow phone line status LEDs (one for the primary line, one for the secondary line) illuminate when phone line voltage drops below 4.5 -7.5 VDC without a corresponding 8-13mA increase in current. The panel monitors both phone lines. The D928 switches phone lines to the panel at regular intervals so that the panel can test each phone line.
Location To allow fire alarm communications to take priority over other telephone communication, wire the D166 RJ31X jack before the in-house phone system to support line seizure (see Figure 20). Wire the jack to the street side of the phone switch, ahead of any PBX equipment. Line seizure provides for a temporary interruption of normal phone usage while the communicator transmits data.
Programming Programming the Panel The procedure below describes how to connect and disconnect the D5200 Programmer. Refer to D5200 Programmer Operation Manual (74-06176-000) for complete information on operating the D5200 programmer. 1. Panel is fully operational during programming: Except when the programmer is sending or receiving, the D9124 is functional while the programmer is connected to it. It will transmit reports as programmed.
Sample Program The D9124 Program Record Training Sheet (74-06802-000) shows the programming required to support the D1256 Fire Command Center and power indicating circuit supervision. The program entries shown on this sheet are those which are loaded into the D9124 before it’s shipped from the factory. Further Programming Required: These entries are necessary, but not sufficient by themselves to set up the panel. You must complete this program for the D9124 to function.
Automatic Test Reports The D9124 can generate automatic test reports. Use this feature to test the phone lines. NFPA 72 Central Station and Remote Station standards require that you send a test report at least every 24 hours. Test report schedules are programmed in the Skeds section of the D9112B Program. See S## Function Code selection number 9–Test Report for programming requirements. You can defer the test report if the panel generates any report other than the automatic test report.
Testing The System Fire Test Use this function to test fire points to be certain they function properly. You can review untested points at the command center to help pinpoint any problems. Upon initiation, the fire test will test the fire alarm output and activate the command center fire sounder for two seconds. The AC will be disabled for four minutes in order to test the system’s battery power. If the battery cannot maintain the system for the four minute period, the command center will appear to go dead.
Service Walk Test The Service Walk Test differs from the standard Walk Test in that POPITs whose addresses are set for a point number not programmed in the panel appear in the test. Service Walk Test only available at command centers with panel wide scope: See Command Center in the D9112 Control/Communicator Program Entry Guide (74-06145000) for a description of command center scope.
Troubleshooting Guide Introduction Radionics provides this guide to help you troubleshoot problems with the D9124. To prevent problems from occurring, read the preceding sections of this manual and the program entry guide to verify that the panel is correctly installed and programmed. Self Diagnostics The D9124 performs a series of self diagnostic tests of its hardware, software, and program at start up and reset.
SERVC BATT LOW Battery Voltage Low If battery float voltage at terminals 4 and 5 falls below 12.1 VDC, a SERVC BATT LOW appears in command center displays. See Battery and Power Reports in this section for probable causes and remedies. Pressing TROUBLE SILENCE silences the buzzer. The display clears when battery voltage reaches 13.7 VDC. SERVC BATT MSING Battery Missing, Shorted, or Reversed If the panel can not detect a battery at terminals 4 and 5, a SERVC BATT MSING appears in command center displays.
Phone Line Trouble Phone line problems that are not corrected can result in the D9124 going into Communications Failure. You can program the D9124 to monitor one or two phone lines. See the D9112B Program Entry Guide (74-06145-000) for programming instructions. If you enable the phone line monitor, SERVC PHONE LINE #1 (or 2 if two lines are used) appears in the command center’s display when the D9124 detects a problem on the phone line.
Communications Failure The D9124 goes into Communications Failure after ten unsuccessful attempts to reach the receiver. Follow the Phone Line Trouble procedure to verify that there is no problem with the phone lines at the D9124 installation. If the phone lines are good, monitor the lines (preferably at the receiver) for the symptoms listed below. Symptom Diagnosis The line rings but the D6500 receiver does not pick up. Line is not ringing at the receiver. 1.
Communications Failure (continued) Symptom Diagnosis Remedy The receiver answers the call and provides an initial “handshake” acknowledgment, but does not acknowledge the D9124's report transmission with a “kiss-off” acknowledgment . The receiver is not compatible with the D9124's transmission format. Verify that the receiver is compatible with the format the D9124 is using (either BFSK or Modem II). See Phone in the D9112 Program Entry Guide (74-06145-000).
Problems with Points If you incorrectly set the switches on a POPIT you may create both a missing and extra point. When you find a missing point, perform a Service Walk Test to search for extra points. See the Security System Owner’s Manual (71-06633-000) for test instructions. Symptom Diagnosis Point appears as missing at control centers and in reports to the receiver. POPIT is not connected or incorrectly connected to the data expansion loop.
Problems with Points (continued) Symptom One or more points remain in trouble or alarm with all devices connected to the sensor loops normal. Faulted points do not generate alarms or troubles as programmed. Panel transmitts PT BUS TROUBLE reports. Erroneous alarm and/or trouble reports may follow PT BUS TROUBLE report. Erroneous alarm and/or trouble events for off-board points appear at control centers. Diagnosis The sensor loop is open, shorted, or grounded.
Problems with Points (continued) Symptom Diagnosis All off-board points are Short on Aux Power, MISSING. terminal 3 or ZONEX power, terminal 24. If only one POPEX module is connected to the D9124, POPEX module may be incorrectly connected to the D9124 or Data Expansion Loop may be disconnected from POPEX module. 74-06799-000-D 2/96 Remedy Terminals 3 and 24 share a common circuit breaker. Check wiring and devices connected to these terminals for shorts or leakage to ground.
Problems with the D8125 POPEX Data Expansion Loops EMI (Electro-Magnetic Interference), excessive resistance, or intermittent grounds, shorts, or opens on the data expansion loop can cause erratic or intermittent functioning of points. Follow the procedures below to find the source of problems on the data expansion loop. EMI If you suspect EMI may be a problem, see EMI on Long Wire Runs in this section. AC induction on the data expansion loops must be less than 10 VAC.
Checking Shielded Cable If improperly installed, shielded cable can create problems rather than solve them. Follow the procedure below to check shielded cable for proper installation. 1. Remove the drain wire for the shield from terminal 10. 10 2. Measure the drain wire for resistance to terminal 10 (earth ground). If there is a short to ground, find and remove the foreign ground from the drain wire. 3. Reconnect the drain wire to terminal 10. 10 4.
Problems with Command Centers Symptom Diagnosis Remedy Command centers show erratic behavior. A supervised address has been entered in more than one command center. Entering a supervised address in more than one command center causes erratic behavior. One or more of the keys is stuck under the faceplate Press each of the keys on the command center to be certain none of them is stuck. Data connections (yellow and green wires) on one or more command centers are reversed, or only one wire is connected.
Watchdog Reset Reports The D9124 sends a WATCHDOG RESET report whenever the panel's CPU (Central Processing Unit) is interrupted and has to start its normal operating sequence over. The on-board buzzer sounds briefly during the WATCHDOG reset. The panel returns to normal operation immediately after resetting. The most common cause of CPU interruption and WATCHDOG RESET reports is static discharge to the panel. Static discharges may also corrupt the panel's program.
Overloaded 12 Volt Power Supply If the load on the D9112LTB's 12 volt power supply exceeds it's capacity, the panel follows a routine to protect itself and the battery. It sends reports to the receiver at several points during this routine. Table 11 shows the D9112LTB LED indicators. Keep in mind that AC power remains at terminals 1 and 2 as you read the overload scenario below.
120 VAC Fuse Fuse F1 protects the D9142, D1601, and D9112LTB from damage due to power surges or over loads. If Fuse F1 is removed or is blown, AC Power is removed from both the D9112LTB and the D9142 Power Supply. Fuse F1 is a type 3 AG, 4 Amp, 250V slow blow fuse. Radionics part number 57-01338-004. Safety Precautions While Handling High Voltage Danger! High voltage is present at the AC Power input terminals and at Fuse F1 near the lower right corner of the D9142 Power Supply.
