INTERCONNECTING
SMOKE ALARMS
WARNING: This smoke alarm should be installed only
by a qualified electrician. Smoke alarm
installation must be in accordance with
the requirements of Article 760 of the
National Electrical Code and any local
codes that may apply.
IMPORTANT: The model FXW-R is a direct replacement
for Firex models FX1014, FX1020, FX1106
and FXW-1A. Model FXW-R cannot be inter-
connected with any other smoke alarm.
IMPORTANT: Do not interconnect Firex smoke alarms
with yellow interconnect wires to Firex
smoke alarms with orange interconnect
wires.
IMPORTANT: Do not attempt to interconnect with any
other type of device or manufacturer’s
brand.
• Interconnect wire must be #18 AWG minimum solid or stranded
wire. When interconnecting, maximum wire length between any
two is 1,500 feet for #18 AWG or 4,000 feet for #14 AWG (20
OHMS loop resistance).
• As many as 12 Model GC & PG40 (6 for Model G-6) smoke
alarms may be interconnected.
• As many as 12 Model FXW-R smoke alarms may be interconnected.
• Connect smoke alarms to a dedicated AC branch circuit. If local codes
do not permit, be sure the neutral wire is common to both phases.
LED INDICATORS
This smoke alarm features an LED indicator which can be seen
through the Push-to-Test button. The LED indicates the following:
Blinks once a minute — indicating normal operation.
Blinks once a second — smoke alarm senses smoke and
simultaneously sounds an audi-
ble alarm.
Blinks once approximately — False Alarm Control™ (FAC)
every 10 seconds feature activated (model GC only).
OFF — another smoke alarm in the
(Interconnected system only): network has sensed smoke and
is signalling this alarm.
FALSE ALARM CONTROL™
Model GC features a False Alarm Control™ that, when activated, qui-
ets unwanted alarms for up to 15 minutes.
To use the False Alarm Control™:
Press and release the test button during an unwanted alarm. The
alarm should stop within ten seconds. This means the smoke alarm is
in False Alarm Control™. Just before returning to normal operation, the
smoke alarm will sound two short beeps. This signals the end of False
Alarm Control™.
If the smoke alarm does not go into False Alarm Control™ and contin-
ues to sound its loud alarm horn, the smoke is too heavy and a danger-
ous situation could exist—take emergency action.
NOTE: In an interconnected circuit, False Alarm Control™ must be
activated on the initiating unit.
