General Limitations - First Alert DC10-500 User Manual

General Limitations for Smoke/CO Alarms
This Smoke/CO Alarm is intended for residential use. It is not intended for use in industrial applications where
Occupational Safety and Health Administration (OSHA) requirements for Carbon Monoxide Alarms must be met.
The Smoke Alarm portion of this device is not intended to alert hearing impaired residents. Special purpose Smoke
Alarms should be installed for hearing impaired residents (CO Alarms are not yet available for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that
everyone is involved – from kids to grandparents. Allow children to master fire escape planning and practice before
holding a fire drill at night when they are sleeping. If children or others do not readily waken to the sound of the
Smoke/CO Alarm, or if there are infants or family members with mobility limitations, make sure that someone is
assigned to assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response to the sound of the Smoke/CO Alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke/CO Alarms cannot work without power.
Battery operated units cannot work if the batteries are missing,
disconnected or dead, if the wrong type of batteries are used, or if the batteries are not installed correctly. AC units
cannot work if the AC power is cut off for any reason (open fuse or circuit breaker, failure along a power line or at
a power station, electrical fire that burns the electrical wires, etc.). If you are concerned about the limitations of
battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not reach the sensors. It will only sense 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.
