4-17.3 Installation of Control Heads to Pilot Cylinders
• Electric to N2 1040 cu. in. pilot cylinder (Type “I” Valve)
• Electric to N2 108 cu. in. pilot cylinder
• Lever/Pressure Operated to N2 pilot cylinder
4-17.3.1 Installation of Electric Control Heads to N2 1040 cu. in. Pilot Cylinder
When installed on the Nitrogen pilot cylinder, the Control Head Monitor is not completely snug
against the valve, allowing for easier attachment of the conduit.
1. Remove the protection cap from the nitrogen pilot cylinder actuation port. Ensure the con-
trol head is in SET position (The actuating pin is in the fully retracted or SET position).
2. Insert the Control Head Monitor between the control head and the cylinder actuation port.

WARNING
Before installing a control head on a pilot cylinder valve, ensure the control
head is in the SET position (that is, the actuating pin is in the fully retracted or
SET position). Failure to position the control head in the SET position will result
in accidental discharge and possible personal injury when the control head is
installed on the siren valve.
