Manual call point with glass breaker MC-1

Overview
The Tyco® Model MC-1 (MC-2) manual control station provides a tamper-resistant means for emergency release of Tyco® automatic water control valves. It can interconnect directly via a hydraulic (wet) pilot line or indirectly via a pneumatic (dry) pilot line to a Model DP-1 dry pilot actuator. The MC-2 is a modified MC-1 intended as a trim component for the DV-5A automatic water control valve.

Application
For use with deluge and preaction fire protection systems where local manual emergency release is required.
