Bosch DM 1103 BEX Manuel D’Utilisation

In the event of an alarm, the glass pane (2) is broken
first, then the pushbutton (3) is pressed hard. Thus
the switch triggers the alarm.
A locking mechanism holds the pressed manual call
point.
The pushbutton can be reset with the reset lever.
This does not reset the alarm on the fire panel.
