540 Isolating Relay Module For Fire Mini Modularm

,l’he No. 540 Isolating Relay Modulemust be wired between the No. 535 Control Cabinet and the No, 643 Junction Box on all Fire Mini-Modulat-m installations. It should be installed after all fifty lamp terminals plus terminals Xl, X2, X3, X4 and X7 of the junction box have been wired in parallel to like numbered terminals inside the control cabinet. ( See installation instructions supplied with Fire Mini-Modularm systems.) It  should be located in the lowerleft side of the control cabinet.

1. Connect No. 540 Module terminals X3, X4 and X5 to correspondingly marked terminals inside the No. 535 Control Cabinet. Note that terminals X3 and X4 of the control cabinet will now have three wires  ttached to them: one from the No. 540 Module and two from the junction box. Terminal X5 will be connected to the No. 540 by a single wire only.
2. Connect two wires from terminal 6 of the No. 540 to the terminals marked X5 of the junction box, one wire to each terminal. Spare conductors inside the No. 543 cable  an be’used for this purpose. Note that no direct connection is made between the X5 terminal of the junction box and terminal X5 of the control cabinet.

TROUBLESHOOTING

FIRE MINI-MODUIARM

Before beginning to troubleshoot the Mini-Modularm System:‘

1. Make sure the No. 644 Power Supply is wired properly. The white lead from the control cabinet should be wired to the “protective circuit +” terminal of the No. 644; the black lead to the “common” termina.1, and the red lead to the “6 volts 4 amps +‘I terminal. Terminals 1, 2 and 3 on the No. 644 MUST be wired to terminals 1, 2, and 3 of the No. 97LT or No. 96M Power Pack. Make sure that the No. 644 Power Supply
2. is connected to a 24-hour outlet not controlled by a switch.
3. Make sure that there are no wires “pinched” between the steel plate of ‘the wired panel and the mounting brackets inside the control cabinet. Since there are hundreds of connections behind the wired panel, it is possible that either during mounting or wiring, one of these wires has shorted to the cabinet.
4. Inspect all solder connections made to each of the sockets on the back of the wired panel. Make certain thatnoneof the wiring tabs touch each other.
5. Remove the housing of the display panel and inspect all solder connec- tions made to this unit. Also determine that no two solder lugs or com- ponents are shorting out.
6. Check the wiring to the No. 540 Isolating Relay Module if it has been included with the unit. This module is located in the lower left hand corner of the control cabinet.
   The red, black, green, and white wires coming out from the bottom left hand corner of the wired panel in the control cabinet must be connected to terminals 2, 3, 4 and 6 ,respectively of the No. 540 Module. Detailed information on the wiring of the No. 540 can be found on page 86 of this section.

NOTE :
EARLY PRODUCTION RUNS OF THE MINI-MODULARM DID NOT INCLUDE THE 540.
IF IT IS NECESSARY TO ADD THIS TO YOUR SYSTEM, INSTRUCTIONS ARE SUPPLIED FOR HOOK-UP TO FIRE & BURGLARY MINI-MODULARM SYSTEMS. THEY CAN BE FOUND UNDER NO. 540 ISOLATING RELAY MODULE.

PRODUCT INFORMATION ABOUT FIRE MINI-MODULARM

NOTE : The following feature has been added to the No. 640 Fire Mini- Modularm Display panel manufactured after Oct. 15, IY79. A buzzer and diode have been added to supervise the horn reset feature in the mini-modularm plug- in receiving modules. Whenever an alarm is received, a buzzer will sound as long as the reset button on the display panel is held in. Should a failure occur in any module, which would prevent the horn from sounding on a subsequent alarm from any other subscriber, the new buzzer will stay on when the reset button is released. The buzzer will continue to sound until the faulted module is replaced or the source of the alarm is removed.
This supervisory feature can be added to any existing mini-modulann installation. Simply order P3730 (buzzer) and P460 (diode) and install them as shown below.

Note : To si lence buzzer, if fault cannot be corrected immediately, .insert an SPST switch (e.g. Ademco No. 258) in series here (remote it to a convenient location). THIS IS NOT A RECOMMENDED PROCEDURE, since you will lose supervision if the switch is left in the open position.
