Chapter 4 - OPERATION Section 4-1- Introduction This chapter describes the operating characteristics of the SAFEPATH® Panel.
! Warning: MESSAGES REQUESTED BEFORE AND DURING A TROUBLE CONDITION MAY NOT BE HEARD, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. IF MESSAGES REQUESTED BEFORE AND DURING A TROUBLE CONDITION ARE STILL NECESSARY, THEY SHOULD BE REPEATED WHEN THE SAFEPATH® PANEL IS RETURNED TO NORMAL.
Section 4-4 - Actions That Initiate Alarms Table 4-1 indicates what can initiate an alarm condition and the resulting Dual-Circuit SAFEPATH® Panel actions.

Chapter 5 - Operational Procedures Section 5-1 - Operator Instructions The SAFEPATH® Panel provides an operator console for manually activating the panel. The operator console includes a microphone, a green “NORMAL” LED, a yellow “TROUBLE” LED, a “RESET” push button, a “TROUBLE ACKNOWLEDGE” push-button switch, a “MANUAL/AUTOMATIC” switch, an “ALL-CALL” switch, “ZONE 1”, and “ZONE 2” switches.
Section 5-2 - To Make Live Announcements From Panel 1. Select Zones or use “ALL-CALL” for all zones. See Figure 5-1 for switch locations. 2. Hold the microphone within 2 inches of your mouth, press push-to-talk switch and begin speaking. From Optional Remote Microphone Station (RMS-3) 1. Turn the key switch from the OFF position to the ON position. 2. Select Zones or use “ALL-CALL” for both zones. (See Figure 3 in Appendix B) 3.
NOTE: Acknowledging a trouble condition silences the internal sounder and any external trouble signaling devices. The system will remain in the trouble condition with the yellow “TROUBLE” light on. The system trouble contact will remain in the trouble position until all trouble conditions have been corrected. Any faults, which occur after acknowledgment, will resound the trouble circuit. When the GREEN "NORMAL" LED is ON, the system is functioning properly.

CHAPTER 6 - PERIODIC TESTING AND MAINTENANCE Section 6-1 - Introduction Periodic testing, including the Dual-Circuit SAFEPATH® Panel, all notification equipment and all messages, including their audibility and intelligibility, content and language, sequence, output channel, and priority assignment, must be conducted frequently, at least twice each year, or more often as required by local, state and federal codes, regulations and laws, by qualified personnel to ensure proper operation of all equipment.
• • Malfunctioning modules in the panel shall be replaced immediately. Do not attempt to repair them. Malfunctioning modules should be returned to the manufacturer for repair or replacement. Section 6-4 - Qualified Personnel Qualified personnel are those who can evaluate proper equipment functionality and ensure its proper operation and perform all testing procedures on the SAFEPATH® Panel.
Chapter 7 - Troubleshooting ! Warning: ! Warning: ! Caution: ! Caution: SOME ELECTRONIC COMPONENTS STORE A HIGH VOLTAGE CHARGE, EVEN THOUGH POWER IS NOT CONNECTED, AND CAN CAUSE A DANGEROUS SHOCK IF TOUCHED. DO NOT TOUCH EXPOSED CIRCUITRY ON THE SAFEPATH® PANEL UNLESS THE CIRCUITRY HAS DISCHARGED FOR ONE HOUR AND A SAFE DISCHARGE PROCEDURE IS USED. PROVIDE UL REQUIRED ALTERNATIVE SIGNALING MEANS DURING TROUBLE CONDITIONS AND SERVICING TO ASSURE ADEQUATE PROTECTION OF PEOPLE AND PROPERTY.
5. Turn “ON” the Internal Trouble Sounder. 6. Turn “ON” the RemoteTrouble Audible Output. 7. Turn “ON” a trouble location indicator, if appropriate. If the TROUBLE ACKNOWLEDGE pushbutton is pressed, the internal trouble sounder and the external trouble audible will be silenced. All other trouble indicators will still indicate a trouble condition. The internal trouble sounder and the external trouble audible will resound for subsequent trouble conditions.

! Warning: BEFORE PERFORMING ANY OF THE FOLLOWING TROUBLESHOOTING PROCEDURES, THE PRELIMINARY TROUBLESHOOTING INFORMATION AT THE BEGINNING OF THIS “TROUBLESHOOTING” SECTION MUST BE READ, UNDERSTOOD, AND FOLLOWED. Procedure A If the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “OFF”, and no module LEDs “ON”, a power loss condition has occurred. A power loss condition may be caused by: 1. Loss of AC input voltage and/or battery back-up voltage. 2.
1. Digital Voice Module Inoperable. Perform the following: 1. Replace Digital Voice Module (MDX-2) When replacing digital Voice Module (MDX-2), properly remove the Voice Module Chips (See Figure 9-4 for locations) and the optional Output Channel Module (MDV-OCM) if installed. Install these items in the new MDX-2 prior to the MDX-2 installation in the panel.
5. Replace the Motherboard (DCMB). Procedure F On the DCDC Module, the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, D12 “OFF”, D11 “OFF”, D10 “ON”, and on the SALL-15S module the PWR LED is “ON”, an amplified speaker power output wiring trouble condition has occurred. An amplified speaker power output wiring trouble condition might be caused by: 1. 2. 3. 4. 5. Missing EOLR resistor on the amplified speaker power output. The Amplified Speaker Power Output field wiring is open or shorted.
Perform the following: 1. If the system does not have a remote microphone attached then switch the Remote Microphone DIP switch (RM) “OFF”. (See Figure 3-18 for switch location) 2. Verify field wiring between the panel and the remote microphone station. (See Appendix B) 3. Replace Fuse F1 on the DCDC module. (See Figure 9-3 for fuse location) 4. Replace the Remote Microphone Station.
3. Replace Motherboard. Procedure L On the DCDC Module, the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, D12 “ON”, D11 “OFF”, D10 “OFF”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and the TROUBLE LED is “OFF”, the digital voice module may be completely inoperative. This condition is caused by: 1. 2. 3. 4. Too low input voltage on the digital voice module. Missing or improperly installed program memory EPROM.
Replace MDV-OCM. If TROUBLE LED remains “STEADY ON” then there is circuitry failure on the MDX-2. Replace. There are no field correctable failed circuitry problems. Digital voice modules with failed circuitry shall be replaced immediately, following Section 7-1 - SAFEPATH® Module Replacement Procedure on Page 7-14.
3. The optional Output Channel Module for channel two is not installed or is improperly installed. The number of output channels installed must agree with the number of output channels used in the Programmed Message Kit (PMK). The Standard Message Kit (SMK) is always programmed for single channel output. 4. Failed audio channel on Series MDX-2 or an optional Output Channel Module. If the error occurs while playing a file, the error was due to one of the first three possible causes.
