Should your FireAngel smoke alarm
enter a low battery condition, the
unit will emit an audible ‘chirp’ once
every 48 seconds. When this occurs
you should replace the battery
immediately. Your FireAngel smoke
alarm will continue to warn of this
low battery condition for at least 30
days, however, failure to change the
battery after this time would mean
your smoke alarm has insufficient
power to alert you in a real fire
situation.
BATTERY REPLACEMENT
IMPORTANT:
Only use CR2
size 3V Lithium batteries for
replacement. Use of a battery
other than that recommended
may have a detrimental effect on
the detector’s operation. Use of
the recommended battery should
provide power for 5 years under
normal
operating
conditions,
meaning there is no need for an
annual battery change.
