| The release and
subsequent discharge of the CO2
gas can be effected either manually and
/ or automatically. |
1. MECHANICAL
RELEASE
The fusible link is mounted onto a wire
rope stretched by weights.
Upon heat application, the fusible link
breaks and actuates the release mechanism
at the CO2 cylinder
bank. |
MANUAL
ACTUATION
The manual release actuation is effected
by just pulling the release handle at
the cylinder valve
. AUTOMATIC
ACTUATION
Automatic release occurs according to
the fire hazard detected in the room to
be protected as in total flooding or within
the immediate vicinity of the object to
be protected as in local application.
It can be either mechanical, pneumatic,
electrical or electro-pneumatic. |
2.
PNEUMATIC MECHANICAL RELEASE
The fusible link is mounted onto a wire
rope stretched by weights.
Upon heat application, the fusible link
breaks and actuates a CO2
pilot cylinder. The discharged gas of the
pilot cylinder actuates the release mechanism
at the CO2 cylinder
bank. |
3. ELECTRICAL
RELEASE
Detectors responding to a fire condition
transmit a signal to the detection panel,
which then activate the release mechanism. |
