The Conventional Manual Call Points for Ex Areas are used to manually activate the alarm in zones 1 and 2 at risk of explosion.
The K type call points are encapsulated, intrinsically safe call points and do not require any safety barriers. The DM 1103 B Ex Manual Call Points for ex zones must be connected via a Safety Barrier SB 3 incl. Input/Output Module DCA1192 (see system overview).

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.
