Turbomachinery Package Specification Titan 250 Generator Set
On detection of a fire by the optional fire and gas detection system, the fire control panel
activates the fire suppression system release solenoids located on the water mist
suppression skid. On receipt of this signal, the solenoid actuated control heads activate
the discharge valves on the water cylinders, releasing a water mist into the enclosure. A
pressure switch in the water mist discharge piping transmits an electrical signal to the fire
control panel to activate a release solenoid to close pressure-operated dampers on all
vent openings. The water mist nitrogen actuator valve is also provided with a manual
release lever.
11.3.11 Fire Cylinder Cabinets
When installed outdoors, weatherproof fire cylinder cabinets are available to house the
extinguishing agent. The cabinets are equipped with service doors. The manual pull
levers are routed by cable to the exterior wall of the cabinet.
