not installed correctly. If the AC power is cut off for any reason (open fuse or circuit breaker, failure

smoke or CO at the sensor. Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors. If bedroom doors are usually
closed at night, we recommend you install an alarm device (Combination CO and Smoke Alarm, or
separate CO Alarms and Smoke Alarms) in each bedroom and in the hallway between them.
CAUTION:

of 85 dB at 10 feet (3 meters). However, if the Smoke/CO Alarm is installed outside the bedroom, it
may not wake up a sound sleeper or one who has recently used drugs or has been drinking alcoholic
beverages. This is especially true if the door is closed or only partly open. Even persons who are awake
may not hear the alarm horn if the sound is blocked by distance or closed doors. Noise from traffic,
stereo, radio, television, air conditioner, or other appliances may also prevent alert persons from hearing
the alarm horn. This Smoke/CO Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes damage, injury, or death, since smoke
from some fires may not reach the unit immediately. Examples of this include persons smoking in bed,
children playing with matches, or fires caused by violent explosions resulting from escaping gas.
