Voltage monitoring
During
battery operation without any external power supply
, only
the voltage provided by the batteries is monitored. If the voltage is
below the lower threshold of 4.8 V, a fault report is sent to the alarm
control panel and the user is informed. The external power supply is
not monitored in this mode.
During
operation with an external power supply
, a fault report is
sent to the alarm control panel as soon as the external power supply
is interrupted. The indoor sounder then automatically continues to be
powered by the batteries. The corresponding notification on the
alarm control panel informs the user about this. The batteries can be
monitored as described above.
