HOW TO INSTALL THIS SMOKE ALARM
CAUTION
Do not use super glue or silicon caulk on or near the alarm! Fumes
from these products can coat and permanently damage the sensor.
DO NOT remove or disconnect the battery or turn off AC power to
quiet unwanted alarms. This will remove your protection. This alarm
features a Quick Quiet™ False Alarm Control button which, when
activated, will quiet unwanted smoke alarms for up to 15 minutes.
DANGER
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.
WARNING
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).
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.
All wiring shall be installed per NFPA 70, Articles 760, 770, and 800.
DO NOT connect this smoke alarm to any other type of smoke, CO, heat,
or combination alarm or auxiliary device except those listed in this manual.
WHILE AC AND AC/DC SMOKE, CO AND HEAT ALARMS CAN BE INTER-
CONNECTED, ONLY WHEN AC POWER IS ACTIVE WILL ALL UNITS
ALARM WHEN ONE UNIT SENSES A HAZARDOUS CONDITION. WHEN
AC POWER IS DISCONNECTED, 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. WHEN POWER IS DISCONNECTED, INTER-
RUPTED OR NOT PRESENT FOR ANY REASON, AC-ONLY POWERED
SMOKE, CO, OR HEAT ALARMS WILL NOT OPERATE!
Install alarm on any 4-inch octagon or single gang junction box only.
Required Power Supply
• Use #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).
• Model FADCP requires constant 120-volt AC power AND/OR a working
9-volt battery to operate properly. The alarms WILL NOT work if AC power
is not connected or has failed or been interrupted for any reason and the
battery is removed, drained or improperly connected. DO NOT use any
other kind of battery except as specified in this manual.
• 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.
• This alarm can be in an interconnected system of up to 18 FireX alarms,
including no more than 12 smoke alarms. It can be interconnected with
FireX models FADCP (4490 Series), FPAMV (11000 Series), FADCM (12000
Series), GCM (12400 Series), FADC (4618 and 5000 Series), TPCI (4671
Series), ADC (4518 Series), PAD (4480 Series), FPAD (4580 Series), G (406
Series), GC (4121 Series), or PG (484 Series) smoke alarms, and as many
as 6 Firex model ADH (5700 Series) heat alarms and/or COE (10000 Series)
or COEA (10400 Series) alarms or a combination of the two, for a total of
not more than 18 interconnected devices.
• Unique power connector prevents interconnection with incompatible
smoke and combination alarms or security systems.
• Many solar power, wind power, and backup power systems use inverters
that make square or non-sinusoidal AC waveforms. Such waveforms can
damage the alarms. These alarms should be powered only by electrical
systems that make true sine waves. If you are not certain if your inverter
makes true sine waves, contact the manufacturer of the inverter.
1. Ensure that power to the area where you will
work is turned off at the circuit breaker or
fuse box.
2. With a wire nut, connect the white wire from
the alarm wire harness to the white (neutral)
household wire(s).
3. With a wire nut, connect the black wire from
the alarm wire harness to the black (120V AC)
household wire(s).
4. To interconnect alarms, use a
wire nut to connect yellow wire
from alarm wire harness to inter-
connect wire(s) between alarms.
If the alarms are not being inter-
connected, cover the end of the
yellow wire with electrical tape.
