If your mains power fails, the Power Supply with Battery Backup will beep once
and automatically switch to its backup battery power.
When only around 40% of the battery power remains (after about 3 to 3.5 hours),
the Power Supply with Battery Backup will turn off to save the remaining 40% of
backup battery power (about 1.5 to 2 hours). This saved power can then be used
to make emergency calls if needed.
What happens when only 40% of the battery power remains?
The battery power indicator will flash and the Power Supply with Battery Backup
will begin to beep four times a minute. Once the beeping stops, the Power Supply
with Battery Backup will turn itself off to preserve the remaining power for use in
case of an emergency.
How to access the remaining backup battery power
in emergencies
Press and hold the BATTERY EMERGENCY USE button for
two seconds until the power supply beeps once and all 4 lights
flash. This will provide around a further 1.5 to 2 hours of power.
After this, you can’t turn the battery power off again.
After the battery is completely flat, the BATTERY EMERGENCY USE butto will
not work again until mains power has been restored and the battery is recharged.
The battery is designed to be continually recharged until it has reached the end
of its life and needs to be replaced - estimated to occur every three to five years
if used in accordance with the guidelines.
Alarm silence function
You can silence audible alarm sounds. Press and hold
the ALARM SILENCE button to temporarily silence or
re-enable the alarm sounds for either 24 hours or longer:
You should only
silence alarms
when absolutely
necessary as they
are designed to
alert you when your
battery is in need
of replacement,
missing or running
low and will soon
be flat.
