INSTALLING A SINGLE (STAND-ALONE)
SMOKE ALARM
Tools you will need: Standard/Flathead screwdriver.
ELECTRICAL SHOCK HAZARD. Turn off power to
the area where you will install this unit at the circuit
breaker or fuse box before beginning installation.
Failure to turn off the power before installation may
result in serious electrical shock, injury or death.
To install this unit, follow these steps:
1. Remove the mounting bracket from the base, and
attach it to the junction box.
2. Using wire nuts, connect the power connector to
the household wiring.
• Connect the white wire on the power connector
to the neutral wire in the junction box.
• Connect the black wire on the power connector
to the hot wire in the junction box.
• Tuck the orange wire inside the junction box.
It is used for interconnect only.
3. Plug the power connector
into the back of the
Smoke Alarm.
4. Position the base of the Smoke Alarm over the
mounting bracket and turn. The Alarm can be posi-
tioned over the bracket every 60°. Turn the Smoke
Alarm clockwise (right) until the unit is in place.
5. If you are only installing one unit, restore power to
the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore
power until all Smoke Alarms are completely
installed. Restoring power before installation is
complete may result in serious electrical shock,
injury or death.
6. Make sure the unit is receiving AC power. Under
normal operation, the Green power indicator light
will shine continuously.
7. If the Green power indicator light does not light,
TURN OFF POWER TO THE JUNCTION BOX
and recheck all connections. If all connections are
correct and the Green power indicator still does
not light when you restore the power, the unit
should be replaced immediately.
Model 4120SB Only: During installation, if you
accidentally press the Silence button, the alarm will
“chirp” once a minute for up to 15 minutes and the Test
feature will be temporarily disabled. This is normal.
The “chirping” will stop once the alarm returns to
normal operation.
