• AC smoke alarms require constant 230V AC, 50Hz power to operate

properly. Mains-powered smoke alarms WILL NOT work if AC power is not
connected or has failed or been interrupted for any reason. Models I240C,
PAD240 and PADC240 require a working 9-volt battery to operate properly in
the event of a power failure. Models IAR230C and PAR230 require a mini-
mum of 2 full days under mains power to reach full backup capacity. DO
NOT use any other kind of battery except as specified in this manual. DO
NOT connect this smoke alarm to any other type of smoke alarm or auxiliary
device, except those listed in this manual.

• DO NOT remove or disconnect battery or turn off AC power to quiet

unwanted alarms. This will remove your protection. Open windows or fan the air
around smoke alarm to silence it. Models GC240, I240C, IAR230C, PG240,
PAR230 and PADC240 smoke alarms feature a False Alarm Control button which,
when activated, will quiet unwanted alarms for up to 15 minutes. 

• The Push-to-Test button accurately tests all smoke alarm functions.

DO NOT use any other test method. Test smoke alarm weekly to
ensure proper operation. 

• This smoke alarm should be installed only by a qualified

electrician. 

• This smoke alarm is designed to be used inside a single family

household only. In multi-family buildings, each individual living unit
should have its own smoke alarms. Do not install in non-residential build-
ings or places which house many people like hotels, motels, dormitories,
hospitals, nursing homes, or group homes of any kind. This smoke alarm
is not a substitute for a complete alarm system.
