The WS-LD uses one 9V alkaline battery as its power source. The battery is good for at least 3 years
before it needs changing.
Low battery detection operates at a threshold of 3.3V ±10 % where the WS-LD has enough reserve
power to typically operate for 3 months before complete exhaustion. The WS-LD low battery signal will
be enunciated by one beep for every 45 secs.

signal will be sent to the Control Panel along with the alarm signal transmission for the
Control Panel to display the status accordingly.
