The Pyro-Chem 551203 NMCH Control Head is a mechanical control head with no local manual actuation lever, engineered to connect to the cylinder valve and support a fusible link detection line, a remote mechanical pull station, and a mechanical or electric gas shut-off valve, per Pyro-Chem's own MCH3/NMCH3 product documentation. Because it omits the local actuation handle that the standard MCH3 head has, the NMCH3 variant is specified for installations where the system must be fired only from a remote pull station or automatic detection, not by a lever at the control head itself.
Key Features
- Mechanical control head connecting to the cylinder valve, fusible link line, remote pull station, and gas shut-off valve
- "No local actuation" design — omits the manual lever present on the standard MCH3 head
- Used across both Kitchen Knight II (wet chemical) and Monarch (dry chemical) system lines
Technical Specifications
- Designation: NMCH (No Local Actuation Mechanical Control Head)
