SMOKE ALARMS

necting, maximum wire length between any two is 1,500 feet for
#18 AWG or 4,000 feet for #14 AWG (20 OHMS loop resistance).

This smoke alarm may be interconnected with as many as
17 other Firex model AD, ADC, PAD and FX1218 smoke alarms,
6 of which may be Firex model ADH heat alarms for a total of
not more than 18 interconnected devices. DO NOT connect to
any other type or model smoke alarm.
•
Connect smoke alarms to a single AC branch circuit. If local codes
do not permit, be sure the neutral wire is common to both phases.
LED INDICATOR(S)
Models AD, ADC and PAD feature two separate LED indicators.
Model FADC features one combined LED indicator. The following
section explains what condition the LED indicator is describing:
• Constant GREEN on - AC power is present
• GREEN is off - AC power is NOT present
• RED blinks once a minute - indicates presence of working
battery
• RED blinks once a second - smoke alarm senses smoke
and simultaneously sounds an
audible alarm
• RED blinks once every 10 - smoke alarm is quieting an
seconds unwanted alarm (Models
ADC and FADC only)
• Constant RED on - indicates that this smoke alarm
(Model FADC only) initiated an alarm in an inter-
connected system. (Press the
test button to reset.)
• RED is off (interconnected - another smoke alarm in the
systems only) network has sensed smoke
and is signaling this alarm.
