Pneumatic Fire Ventilation System

Description of Pneumatic Fire Vent System For the drive of the Pneumatic Fire Ventilation System, its principle of operation consists in using kinetic energy of the carbon dioxide that is stored under high pressure in a container (cartridge). In the event of fire, the drive system is activated automatically or manually. Tripping (alarm) signal will cause punching the cartridge and release of gas that fl ows through piping to the actuator and moves its piston rod. Piston rod opens the fire vent that provides escape way of the building for smoke and hot air. Pneumatic drive system may be activated automatically or manually.
Automatic activation of the system is initiated by:
1. Actuation (burst) of the thermal trip temperature fuse.
2. Triggering (burst) temperature for the fuse is 68°C - 141°C.
Actuation of f re detection sensors (e.g., smoke sensor) in fire alarm system, if any. Manual activation is made by:
1. Actuation of the alarm lever or button in alarm box.
2. Actuation of the fire alarm system manual button.
Pneumatic piping is made of copper pipe with diameter of 6 mm or 8 mm.
