operated as follows:
1. Battery (DC) Only Stand Alone
2. Battery (DC) Only Interconnect to another
battery operated Firex alarm.
3. AC w/Battery Back-up, Single Station
Stand-alone
4. AC w/Battery Back-up Interconnected with
other Firex AC and AC w/Battery Back-up
Alarms.
Installation for Battery (DC)
Operation Only
1. Remove the mounting plate. Hold the alarm
and turn the mounting plate clockwise to
separate it from the back of the alarm.
2. Hold the mounting plate against the ceiling or
wall in the desired position and use a pencil to
trace the inside of the mounting slots.
3. Use a 3/16” (5mm) drill bit to drill through the
center of the outlines you made in Step 2. (For
DC Interconnect–use an appropriately sized
hole saw for interconnect hole.)
4. Insert screw anchors into the drilled holes. If
necessary, gently tap anchors with a hammer
until they are flush with the mounting surface.
5. Attach the mounting plate to the mounting sur-
face with the mounting screws provided.
6. Position the combination smoke and CO alarm
on the mounting plate and turn clockwise to
lock the unit into place.
7. Activate the battery.
Remove the arrow
tab and close the
battery door.
The combination
alarm will beep
briefly and the RED
light will flash as
the battery door is
closed.
8. Test the combination alarm. See “TESTING
THE COMBINATION ALARM”.
IMPORTANT!
To interconnect two Battery Operated (DC)
alarms, trace a third point 1-3/8” to 2”
(3.5cm to 5cm) where the interconnect wire
will come through mounting surface to
connect to the alarm, then proceed to
“INTERCONNECTING TWO BATTERY (DC)
ONLY ALARMS”.
