Firex 501 Mode D'emploi

Use this manual to install your Firex Multi-Function Relay Module (MFRM). This module can be used only with the following Firex Smoke, Smoke/CO,
and CO alarm models (and item number series): G-6 (406 series), G-18 (418 series), PG (484 series), FADC (4618 and 5000 series), AD (4418 series),
ADC (4518 series), ADH (5700 series), GC (4121 series), PAD (4480 series), FPAD (4580 series), FADCM (12000 series), GCM (12400 series), COE (10000
series), or COEA (10400 series). These are low-voltage interconnect alarms with a YELLOW interconnect wire.
WARNING: A qualified licensed electrician should make all connections following the National Electrical Code and any
other local building codes.
CAUTION: Do not use with any other type of Firex alarm or any other manufacturer's alarms. Doing so will
permanently damage the MFRM. Firex smoke alarms with ORANGE interconnect wires ARE NOT
COMPATIBLE with this module.
SPECIFICATIONS
The MFRM has a single-pole double-throw (SPDT) relay with contacts rated at 120 Volts AC, 5 Amps. The normally-closed (NC) contact (RED wire)
opens upon alarm. The normally-open (NO) contact (BLUE wire) closes upon alarm. The GRAY wire is the relay's common wire.
The MFRM current consumption is 0.005 Amps AC maximum.
The MFRM can interconnect with up to 18 compatible devices (maximum of twelve (12) Firex smoke alarms and six (6) Firex CO and/or heat alarms).
More than the NFPA and UL maximum interconnections may cause problems.
NOTE: The total number of alarms in an interconnected circuit depends on the specific Firex alarm model used.
CAUTION: The MFRM should NOT be used to increase the maximum number of Firex alarms permitted in multiple
station operation (refer to the Firex alarm manual).
CAUTION: The MFRM will not operate without AC power.
INSTALLATION INSTRUCTIONS
Install the MFRM in its own separate junction box. A four-inch square by two-inch deep box is typically used. A qualified licensed electrician should
make all connections following the National Electrical Code and any other local building codes.
1. Turn off main power at the circuit breaker or fuse box to the branch alarm circuit.
2. Install and wire your Firex AC alarms as shown in their owners' manuals.
3. Connect the WHITE wire of the MFRM to the WHITE (neutral) wire of the AC line.
4. Connect the BLACK wire of the MFRM to the BLACK (hot) wire of the AC line.
5. Connect the YELLOW wire of the MFRM to the interconnect line.
6. Connect the GRAY (common) wire of the MFRM to the BLACK (hot) wire of the controlled AC circuit, if you are using line voltage to control the
secondary device.
7. Connect the RED (NC) wire of the MFRM to the load of the controlled AC circuit.
Connect the BLUE (NO) wire of the MFRM to the load of the controlled AC circuit.
8. Connect the ORANGE (select) wire of the MFRM as follows:
• To the WHITE (neutral) wire of the AC line if the MFRM should respond to both CO and smoke alarms.
• To the BLACK (hot) wire of the AC line if the MFRM should respond to only CO alarms.
• Cap, tape off, or attach a wire nut to the ORANGE (select) wire if the MFRM should respond to smoke alarms only.
9. Install the MFRM in the junction box.
10. If you are connecting this relay with models FADCM, GCM, COE, or COEA (refer to item number series at the beginning of these instructions),
you must perform an INTERCONNECT TEST at the alarm in order to verify the correct operation of the relay throughout the
interconnected system.
NOTES:
1. Cap each unused wire with a wire nut.
2. The controlled branch circuit is typically a separate circuit from the alarm branch circuit.
3. The wiring diagram on page 2 is an example showing how to connect the MFRM into the alarm interconnect circuit.
