System Overview
For DM 1103 B‑Ex:
Pos. Description

2 Ex area zone 1 or 2

Functions
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.
