FIRE & SMOKE CONTROL EQUIPMENT

fire damper

1. FIRE DAMPER

90 min. fire rating as per UL-555

These dampers are made of heavy gauge galvanised steel with multi blade construction. The blades are fitted with chrome plated shafts and self lubricated phosphorus bronze bushes.

The dampers are also provided with a jamb seal (compression type) on sides to prevent spread of smoke & fire. The blades of the damper are held in the 'open' position by a high tensile spring and a fusible link. The fusible link is UL 0 Stamped and melts at 74 C or through a thermal cut-off and Solenoid, causing the damper to close upon heat detection, blocking the opening and thus preventing the spread of fire into the adjoining compartment.

The fire damper are available in standard depth of 150 mm with flange of 25/40 mm suitable for duct mounting.

2. FIRE SMOKE DAMPER

CLASS I 90 min fire rating with Class I leakage as per UL-555/555S

These dampers are made of heavy gauge galvanised steel having multi blade construction. The blades are fitted with chrome plated shafts and self lubricated phosphorous bronze bushes. The dampers are also provided a with jamb seal (compression type) on sides and blade edge to prevent spread of smoke & fire.

These are motorised dampers with a pair of manually resettable, fixed setting, 0 thermostats mounted in the air stream, with cut-offs at 74 C and 177 C causing the damper to close just below 74 C. Depending on demand from the smoke control system it can be opened/closed with a secondary temperature override at 177 C.

Available with UL873 listed spring return electric actuator. These fire smoke dampers are available with a integral sleeve of length 406/535 mm suitable for 4/9 inches wall mounting.

3. FIRE SMOKE DAMPER

CLASS II 90 min fire rating with class II leakage as per UL-555/555S

These dampers are made of heavy gauge galvanised steel having multi blade construction. The blades are fitted with chrome plated shafts and self lubricated phosphorous bronze bushes. The dampers are also provided with jamb seal (compression type) on sides to prevent the spread of smoke & fire.

These are motorised dampers with a UL stamped thermal cut-off mounted in the air stream, which fuses at 74 C and causes the damper to close just below 74 C, thereafter, it can be opened/closed from the smoke control system.

Available with either spring return electric or pneumatic actuator.

4. CONTROL OPTIONS

 

SMOKE DETECTOR MODULE

Accommodates photoelectric sensor. It is easy to clean and maintain since detector heads can be removed by simply twisting-in, twisting-out of its housing. It samples air currents passing through the duct.

stand alone control module

STAND ALONE CONTROL MODULE

On a signal from smoke detector module or Central Fire Alarm Panel, it sends out control signals to fans, blowers and air conditioning systems through control module and hence preventing spread oftoxic smoke and fire gases through the protected areas.

DAMPER CONTROL AND MONITORING SYSTEM

Intelligent Damper Control and Monitoring System, provides supervisory control and monitoring for Fire Smoke Damper. With signals from an optional smoke detector installed in zone with VAQ station and its controller at supply air to provide early alarm in case of fire and at the same time strategise and control VAQ stations, fire smoke damper and other smoke exhaust systems using this system.
