Conventional Manual Call Points for Ex Areas

Conventional Manual Call Points for Ex Areas

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).
