
It sends a radio code of low battery LWB
The code is sent after each alarm or supervision transmission.
Depending on the control panel or receiver model, the alert is visualized on display or LED.
Furthermore, if enabled, an SMS is sent to telephone numbers stored.

It blinks 9 times the transmission LED (must be enabled by closing the jumper JP7 ): the LED blinks after each alarm or supervision
transmission.
Note : the low battery alerts will continue until the battery is replaced.

When the battery must be replaced:
 Disconnect the old battery
 Press and hold the tamper switch for about 3 seconds (discharge of the circuit)
