The Electric / Pneumatic Control Head offers two methods to actuate the Amerex Dry Chemical
System and ICS System. One method is to manually discharge the system using pressure from a Nitrogen Cylinder of a remote Manual Actuator through the Pneumatic Actuation Network. The second method is to discharge the system with use of an electrically actuated Linear Actuator.
The Electric / Pneumatic Control Head is constructed of extruded brass and bolts directly to the
top of the Agent Cylinder Valve. When supplied with nitrogen pressure from the Pneumatic
Actuation Network through 1/4” NPT female ports on either side, the piston inside the Electric /
Pneumatic Control Head extends and depresses the Agent Cylinder Valve stem, releasing the
corresponding Agent. The top of the Electric / Pneumatic Control Head has a threaded hole that
accepts the Linear Actuator (P/N 22579 or 20500). The Linear Actuator, when activated, will
force the piston inside the Electric / Pneumatic Control Head down to depress the Agent
Cylinder Valve stem, releasing the Agent.
