How to Install Your CO Alarm
Once you have decided the best place to install the CO alarm(s), follow these
steps:
ELECTRICAL SHOCK HAZARD. Turn off power at the main fuse box or circuit
breaker by removing the fuse or switching the circuit breaker to the OFF position.
Check local codes for specific mounting requirements in
your area.
1. From back of CO alarm, slide mounting plate and lift
from base. See Figure 4.
2. Connect new 9-volt battery to battery connector inside
compartment and slide door closed snapping it into place.
New 9V battery comes from the factory installed backwards
inside the battery compartment. Replace battery with Eveready
216, 522, 1222 or equivalent from your local retailer.
3. Align mounting plate with junction box mounting holes.
4. Gently pull household wires through center hole of mounting plate.
5. Secure mounting plate to junction box.
6. With a small wire connector, connect white wire from the CO alarm to white
household wire.
7. Connect black wire from the CO alarm
to the black household wire.
8.
For interconnecting CO alarms only:
• Use #18 AWG minimum solid or
stranded wire. When interconnecting,
maximum wire length between any
two is 1,500 feet for #18 AWG or
4,000 feet for #14 AWG (20 OHMS
loop resistance.) See Figure 5.
• This CO alarm may be interconnected with as many as
11 other Firex CO alarms. DO NOT connect to any other
type or model CO alarm or other device.
• Connect CO alarms to a single AC branch circuit. If local codes do not permit
connection to a single AC branch circuit, be sure the neutral wire is common to
all circuits used.
9. Align tabs on back of base with slots on
side of mounting plate. Slide base down to
lock into position. See Figure 6.
10. Turn power on at the main fuse box or circuit
breaker. The CO alarm will flash the red LED
and emit a short beep during its power-up
cycle. The green POWER light will stay on as
long as the CO alarm is receiving AC power.
