Interconnecting Multiple Alarms (continued)...
• The total length of wire interconnecting the units
should be less than 1000 feet (300 meters). The
interconnect wire should be #18 gauge or larger,
rated at least 300V.
• If an interconnect wire is not already part of your
household wiring, you will need to install one.
This type of wire is commonly available at
Hardware and Electrical Supply stores.
Failure to meet any of the above requirements
could damage the units and cause them to mal-
function, removing your protection.

the white/gray stripe wire on the power connector.
3. 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.
• Connect the white/gray stripe wire on the
power connector to the interconnect wire in
the junction box. Repeat for each unit you are
interconnecting.
4. Plug power connector into the back of the Alarm.
5. Position the base of the Alarm over the mounting
bracket and turn. The Alarm can be positioned over
the bracket every 60°. Turn the unit clockwise
(right) until the unit is in place.

“THIS SIDE UP”, so it faces the ceiling.
ELECTRICAL SHOCK HAZARD. Do not restore
power until all Alarms are completely installed.
Restoring power before installation is complete
may result in serious electrical shock, injury or
death.
6. Make sure each unit is receiving AC power. Under
normal operation, the Green power indicator light
will shine continuously.
