2. A Heat Alarm is beeping about every 40 seconds.
- If it is a 9V Replaceable Battery model then replace the battery.
- If it is a 10 Year Lithium Battery model this indicates that the Lithium Battery is
partially depleted and the Smoke Alarm needs to be replaced. (check the “replace
by” date marked on the side of the Alarm).
5.3.2 Battery Replacement - (9V Replaceable Battery models only)
A fresh Alkaline Battery should last for over a year. When the battery power is low
and replacement is necessary, the Smoke Alarm will “beep” and the red light will
flash at the same time about every 40 seconds for at least 30 days. The Heat Alarm
will also beep once per minute, but the red light will not flash at the same time when
the battery is low. The battery must then be replaced. Also, replace the battery if the
Alarm does not sound when the Test Button is pressed. For maximum reliability,
replace the battery at least once a year. When you replace the battery you must
press the Test button to check that the Alarm is functioning correctly. Only replace
the battery with one of the following alkaline batteries: Duracell MN1604, Energizer
6LR61, Philips 6LR61, Varta 6LR61 or the Ultralife U9VL-J lithium battery. The
lithium battery willl last longer than an alkaline battery.
All Models: Prolonged exposure to low or high temperatures or high humidity may
reduce battery life. Prolonged periods of alarm will also reduce battery life.
5.4 Cleaning your Alarm
Clean your Alarm regularly. Use a soft bristle brush or the brush attachment of your
vacuum cleaner to remove dust and cobwebs from the side slots where the smoke/
heat enters. To clean the cover, wipe with a damp cloth and dry thoroughly.
WARNING: Do not paint your Alarm.
