operation and places that constantly exposed to certain elements. Ventilation holes are also available as option for proper circulation. It is commonly installed in places such as shop houses, utility center, industrial installations, stalls and HDB.
 

  • Aluminium has 1/3 density of mild steel, making it light weight

  • Manually operated by hand chain 

  • Automatically operated by control box

  • Single span up to 6m x 6m in dimension

  • Custom perforated
    slat are available for good air ventilation and visibility.

Side Guides

The side guide consists of a customized ‘U’ shaped profile made up of 2mm thick aluminium. The side guide shall take an overall nominal dimension of 45mm (width) x 32mm (depth).

Bottom Bar

The bottom bar shall be constructed of extruded aluminium inverted ‘T’ shaped bar. It is the last slat which is situated at the bottom of the entire curtain and it is used to maintain the door rigidity.

 

Roller Barrel

It shall only consist of a single heavy-duty steel pipe, forming only a single barrel. The drive assembly is made up of steel circular plates fitted to the steel solid shaft round bar on one end and a circular plate with tri-legged slot on the other end.

 

Shutter Hood

The frame is fabricated from 30mm x 30mm angle bars forming a truss frame, with 0.8mm colourbond steel sheet cover; to conceal the shaft assembly. The shutter hood’s dimensions shall be between 365mm to 600mm in both height and depth.

Shutter Operation 

Motor

Each fire shutter shall be equipped with only 1 motorized operator. The shutter operator is equipped with built-in limit switch, built-in thermal protector, built-in brake release system, manual hand chain, and one unit of 3-ways push button (Up, Stop, Down) switch with cylinder lock integrated in a stainless steel cover. The limit switch shall ensure the shutter stops automatically at desired levels. In the event of power failure, the shutter can be operated manually by pulling the hand chain.

Power Requirements

The power source shall be single phase 230V x 13amp or 3-Phase 415V x 20amp, 50Hz each depending on the size of the shutter. 

Operating System

Motorized roller shutter can be operated by using the push button, which is located approximately 1.5metres above floor level without counter balance system.

Manual Hand Chain

The hand chain is provided to manually operate the roller shutter curtains in times of power or motor failure. It consists of a gear reduction chain block.
