4. CO Alarm Test. Ten second test. Horn
sounds: 4 alarms, 5-second pause, 4 alarms,
5-second pause. BLUE light flashes rapidly.
During the CO alarm test, other interconnected
CO alarms or combination smoke-CO alarms
also will sound their alarms to verify the inter-
connect is working.
As long as you press the Smart Button the
smoke and CO alarm will alternately test the
smoke and CO sensors and cause a remote
alarm condition on all interconnected smoke,
heat, CO, and smoke-CO alarm units. Use a
broomstick or similar long object to press the
Smart Button to keep a distance between you
and the 85 db alarm.
5. Fault Warning.
If alarm sounds two short
beeps followed by YELLOW light flashing
twice, the unit is detecting a fault. Push the
Smart Button to reset and start a self test. If
the Fault Warning persists, the alarm must be
replaced immediately.
6. If no alarm sounds, turn off power at main fuse
box or circuit breaker and check wiring and con-
nection. Turn on power and retest the unit(s).
Maintenance and Care
In addition to weekly testing, this smoke and CO
alarm requires yearly battery replacement and
periodic cleaning to remove dust, dirt, and
debris.
DANGER
ELECTRICAL SHOCK HAZARD. Turn off power
at main service panel by removing fuse or
switching appropriate circuit breaker to OFF
position before replacing battery or cleaning
smoke and CO alarm.
Battery Replacement
Always turn off power to the alarm circuit before
replacing the battery. Replace the battery at least
once a year or immediately when the low battery
chirp sounds once a minute, even though the
smoke alarm is receiving AC power. If the Low
Battery Warning sounds and a replacement bat-
tery is not immediately available, pushing the
Smart Button silences the Low Battery Warning
for approximately 8 hours. This allows you to
return to sleep, for example, and purchase a new
battery the next day. If you push the Smart
Button and the Low Battery Warning does not
silence, replace the battery immediately.
Use only the following batteries as replacements
in this smoke and CO alarm: Eveready 522,
Duracell MN 1604 or Ultralife U9VL-J.
WARNING
DO NOT USE ANY OTHER TYPE OF BATTERY,
