Master Control Unit MCU 1210 / MCU 1210A

The master control unit supervises and annunciates a suppression system rather than releasing it electrically, which makes it the panel of choice for pneumatically actuated CDS and CIS installations where the cylinder fires itself.

Inbuilt hooter and flasher give local audible and visual alarm without separate sounders, and indicators show mains on, battery on, system healthy and gas released. A dry contact relay (C / NO / NC) passes the signal to plant shutdown or a building management system.

Housed in a powder coated mild steel box, mains supplied at 220 V AC with 12 V DC operation and battery backup, rated 0 to 50 °C.
