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).
