OPERATION PHILOSOPHY
The Inergen system comprises of a bank of cylinders each
connected to a release manifold via discharge
hoses.
The system is capable of electric (through solenoid) and
manual actuation. In normal philosophy electric
actuation is used and in case Electric Actuation fails
to operate, provision of manual actuation is also
provided.
Automatic Release:
Automatic release is accomplished via detectors
installed in the protected areas. Detectors are
installed and programmed on cross zone principle to
avoid accidental release of gas due to malfunctioning /
false alarm. As soon as a fire is detected from both the
detectors, signal is sent to the Fire Alarm Panel.
Potential free contacts are provided in FAP for
switching off AC system. Simultaneously,
respective solenoid valve on the electric actuator
mounted on the cylinder gets energized through panel to
open electrically. The Inergen gas released from
cylinder bank is directed to the area under fire.
Manual release:
Manual release is accomplished by pressing the push
button at a “Manual Push Button Station". Once the
push button has been pressed, the system will be
