Features
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.
