The repeater can be provided with the battery backup option to enable alarm calls in 
case of power failure. The battery backup module supports multiple dial out attempts 
via modem in case of “System engaged” or other communication problems for about 
ten minutes under normal environmental conditions. 
 
The batteries are protected from deep discharge by use of a low voltage disconnect 
unit. A local switch is provided to disconnect the battery backup option during 
maintenance to ensure that all circuits are voltage-free. The switch is located on the 
battery backup module. 
 
The module is directly plugged onto the control module and can be installed on site. 
During the charging process, a green LED on the module indicates that the battery is 
charged at the moment. After finishing the process, the LED will be switched off.
