Installing a Single
(Stand-Alone) Smoke Alarm
Tools you will need: Standard/Flathead screwdriver
DANGER!
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 alarm over the mounting
bracket and turn. The alarm can be positioned
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.
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.
IMPORTANT!
Cat. 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.
DANGER!
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.
