HOW TO INSTALL THIS SMOKE ALARM
This unit is designed to be mounted on any standard wiring junction box up to a 4-inch diagonal size, on either the
ceiling or wall (if allowed by local electrical codes). Read “Where to Install Smoke Alarms” and “Where Not To Install
Smoke Alarms” before you begin installation.
Tools you will need: Standard/Flathead screwdriver.
Installing This Smoke Alarm:
The basic installation of this smoke alarm is the similar whether you want to install one smoke alarm, or interconnect
more than one smoke alarm.
If you are interconnecting more than one smoke alarm, you MUST read “Special
Requirements For Interconnected Smoke Alarms” below before you begin installation.
1. Remove the mounting bracket from the base. Install the mounting bracket to the junction box.
2. Set the foam gasket against the back of the smoke alarm.
3. Using wire nuts, connect the power connector to the household wiring.
4. Plug the power connector into the back of the unit. It will only fit one way. After the connector snaps into place,
tug on it gently to make sure it is secure. (If you need to remove the power connector, insert a flat screwdriver
blade between the power connector and the security tab inside the power input block. Gently pry the tab back
and pull the connector free.)
5. Line up the alignment tab on the base with the alignment tab on the mounting bracket. Turn the unit clockwise
(right) until you hear the unit snap into place.
6. Check all connections.
7. Make sure the smoke alarm is receiving AC power. Under normal operation, the power indicator light will shine
continuously. If the power indicator light does not light, TURN OFF POWER TO THE JUNCTION BOX and
recheck all connections. If all connections are correct and the power indicator still does not light when you
restore the power, the unit should be replaced immediately.
8. Test the smoke alarm. Press and hold the test button on the cover until the alarm sounds (the unit may continue
to alarm for a few seconds after you release the button).
During testing, you will hear a loud, repeating horn
pattern: 3 beeps, pause, 3 beeps, pause.
In an interconnected series, you must test each smoke alarm
individually. The strobe light should flash every time you test the smoke alarm.
IMPORTANT!
If any smoke alarm does not alarm, TURN OFF POWER and recheck connections. If any smoke alarm still does not
alarm when you test it after restoring power, replace it immediately.

STAND-ALONE (SINGLE) SMOKE ALARM ONLY:
INTERCONNECTED SMOKE ALARMS ONLY:
• Connect the white wire on the power con-
nector
to the neutral wire in the junction box.
• Connect the black wire on the power con-
nector to the hot wire in the junction box.
• Tuck the orange wire inside the junction
box.
It is used for interconnect only
Strip off about 1/2” of the plastic coating on the
orange wire on the power connector.
• Connect the white wire on the power con-
nector to the neutral wire in the junction box.
• Connect the black wire on the power con-
nector to the hot wire in the junction box.
• Connect the orange wire on the power con-
nector to the interconnect wire in the junction
box. Repeat for each unit you are intercon-
necting. Never connect the hot or neutral
wires in the junction box to the orange
interconnect wire.
STAND-ALONE SMOKE ALARM ONLY:
INTERCONNECTED SMOKE ALARMS ONLY:
• If you are only installing one smoke alarm,
restore power to the junction box.
• If you are interconnecting multiple smoke
alarms, repeat steps 1-6 for each smoke alarm
in the series. When you are finished, restore
power to the junction box.
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.
Important Installation Parts
The Mounting Bracket The Foam Gasket The Power Connector
The mounting bracket installs
onto the junction box. It has a
variety of screw slots to fit most
boxes. If a junction box is not
already in place, install one using
standard #12 or #14 gauge
copper wire. To remove the
mounting bracket from the
smoke alarm base, hold the
smoke alarm base firmly and
twist the mounting bracket
counterclockwise.
The foam gasket prevents air
currents from coming
through the junction box and
blowing smoke away from
the sensor. It must be
installed to comply with UL
standards. When installing
the foam gasket, line up the
cut-outs with the power
input block on the smoke
alarm.
• The black wire is “hot.”
• The white wire is neutral.
• The orange wire is for
interconnect.
If you need to remove the power
connector, insert a flat screwdriver
blade between the power connector
and the security tab inside the power
input block. Gently pry back the tab
and pull the connector free.
The power connector plugs into a
power input block on the smoke
alarm.
