Installing a Single (Stand-Alone) Alarm (continued)...
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.
Make sure the unit is receiving AC power. Under nor-
mal operation, the Green power indicator light will
shine continuously.
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.
INTERCONNECTING MULTIPLE ALARMS
Interconnected units can provide earlier warning of
fire or CO than stand-alone units, especially if the
incident starts in a remote area of the dwelling. If any
unit in the series alarms, all units will alarm.
To determine which Alarm initiated an alarm, see table:
On Initiating Alarms Red LED(s) Flashes Rapidly
On All Other Alarms Red LED is Off
All wiring must conform to all local electrical codes
and Article 760 of the National Electrical Code (NFPA
70). Refer to NFPA 72, Chapter 2 and/or your local
building code for further connection requirements.

Interconnecting Multiple Alarms (continued)...
AC and AC/DC Alarms can be interconnected.
Under AC power, all units will alarm when one
senses smoke or CO. When power is interrupted,
only the AC/DC units in the series will continue to
send and receive signals. AC powered smoke
alarms will not operate.
Interconnect units within a single family residence
only. Otherwise all households will experience
unwanted alarms when you test any unit in the series.
Interconnected units will only work if they are wired to
compatible units and all requirements are met.
This unit is designed to be compatible with: BRK
