MULTIPLE-STATION INSTALLATION
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.
CEILING MOUNTING:
1. Remove the mounting bracket from the base.
Position the screw slots on the mounting bracket
over the screws in the junction box. Tighten the
screws.
2. Strip off about 1/2” of the plastic coating on the
violet interconnect wire on the power connector.
Interconnected units must meet ALL of the
following requirements:
• A maximum of 18 units total may be
interconnected. (See page 14 for details.)
• The same fuse or circuit breaker must power
all interconnected units.
• The total length of wire interconnecting the
units should be less than 1000 feet. The
interconnect wire should be Type 18 gauge
AWM or larger, rated at least 300V.
• If an interconnect wire is not already part of
your household wiring, you will need to
install one.
Failure to meet any of the above requirements
could damage the units and cause them to
malfunction, removing your protection.
3. Using wire nuts, connect the power con-
nector to the AC power.
• Connect the white wire on the power
connector to the neutral wire (usually
white) in the junction box.
• Connect the black wire on the power
connector to the hot wire (usually
black) in the junction box.
• Connect the violet wire on the power
connector to the interconnect wire in
the junction box. Repeat for each unit
you are interconnecting. Never connect
the hot or neutral wires in the junction
box to the violet interconnect wire.
4. Plug the power connector into the back
of the CO 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.
6. Make sure CO Alarm is secured
to the mounting bracket.
ELECTRICAL SHOCK HAZARD. Do not restore
power until all CO Alarms are completely installed.
Restoring power before installation is complete may
result in serious electrical shock, injury or death.
7. Make sure each unit is receiving AC power. Under
normal operation, the red light (LED) will shine con-
tinuously. Display shows a dash under “READY”.
