Interconnecting AC Only and AC/DC Alarms

Models FADCM (12000 Series) and GCM (12400 Series)
Do not use super glue or silicon caulk on or near the alarm! Fumes from
these products can coat and permanently damage the sensor.
ELECTRICAL SHOCK HAZARD. Turn off power at the main fuse box or
circuit breaker by removing the fuse or switching the circuit breaker to the OFF
position.
This smoke alarm should be installed only by a qualified electrician. Smoke alarm
wiring to be used shall be in accordance with the provisions of Article 210 and
760 of the National Electrical Code, ANSI/NFPA 70, and any local codes that may
apply. Interconnect wire location shall be in accordance with NEC Article 300.3b.
• This combination alarm may be interconnected with as many as 11 other FireX
model FADCM, GCM, FADC, TPCI, AD, ADC, PAD, FPAD, G, GC, or PG40 smoke
alarms, and as many as 6 FireX model ADH heat alarms and/or COE or COEA CO
alarms for a total of not more than 18 interconnected devices.
• It is important to note that this smoke/CO combination alarm IS NOT com-
patible with models FADCQ and COQ8. If more than one model FADCQ, or
more than one model COQ8, is in your home, all must be replaced in order to
achieve a fully operational interconnected system. If models FADCQ and
COQ8 are interconnected with this combination alarm, they will operate as if
they were single station stand-alone alarms, thus eliminating the benefits and
additional protection of an interconnected system.
Models FADCQ and COQ8 are still compatible with all existing FireX AC and
AC/DC smoke alarms.
• This alarm can share the interconnect wire of smoke and heat alarms. The alarm
will automatically sound a smoke alarm signal if smoke is detected by this unit or
any other interconnected smoke alarm, even if the unit is already detecting carbon
monoxide and sounding the carbon monoxide alarm signal.
WHILE AC AND AC/DC SMOKE, CO AND HEAT ALARMS CAN BE INTERCON-
NECTED, ONLY WHEN AC POWER IS ACTIVE WILL ALL UNITS ALARM WHEN
ONE UNIT SENSES A HAZARDOUS CONDITION. WHEN AC POWER IS DISCON-
NECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, ONLY AC/DC
UNITS WILL CONTINUE TO SEND AND RECEIVE SIGNALS AND SOUND AN
ALARM IN RESPONSE TO THE PRESENCE OF SMOKE, CO, OR HEAT, AS
DETERMINED BY THE MODEL OF ALARM THAT IS PRESENT. WHEN POWER IS
DISCONNECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, AC-
ONLY POWERED SMOKE, CO, OR HEAT ALARMS WILL NOT OPERATE.
THIS ALARM SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL
FIRE PROTECTION ASSOCIATION'S STANDARD 72 (National Fire Protection
Association, One Batterymarch Park, Quincy, MA 02269).
• Connect CO and smoke alarms to a single dedicated AC branch circuit. If local
codes do not permit such a wiring configuration or connection, be sure the neutral
wire is common to both circuits or phases.
Installing AC/DC Smoke/CO Alarms as Replacements
with Interconnected Legacy FireX Alarms
Model FADCM and GCM combination alarms are designed to be used as replace-
ment units for most FireX AC and AC/DC smoke alarms with a low voltage intercon-
nect line. These models include G, GC, H, AD, ADC, and FADC. All models listed use
a 3-wire interconnect system. To interconnect with other models, please call our free
technical support line at (800) 445-8299.
IMPORTANT! READ BEFORE INSTALLING THIS SMOKE/CO ALARM WITH
To Install a Combination Unit as a Replacement:
1. Turn off AC power at circuit breaker or main fuse box.
2. Remove old alarm from mounting bracket.
3. Disconnect wire connector from back of unit.
4. Remove wire nuts and connect new wire connector to household wiring. Be
certain not to cross the wiring.
5. Connect wire connector to back of alarm.
6. If mounting bracket is the same, reattach alarm to mounting bracket. Feed wiring
back through hole in mounting surface.
7. Turn on power at main fuse box or circuit breaker.
8. Test Smoke/CO alarm. See "TESTING THE SMOKE/CO ALARM."
9. Model FADCM AC/DC model only: Activate the battery. Remove arrow tab and
close battery door. The yellow light will flash as door is closed.
