Fire Curtain Construction

Two types of horizontal curtain; the Simplex and Duplex. Both the Mini Simplex and Simplex close from one end to the other, whereas the Duplex is used for much larger areas and closes from each end of a void to meet and close in the middle. Each roller is up to 4m wide with a 10m draw.

Metalwork is zinc coated mild steel. This can be painted on site or powder coated to DULUX or RAL colours.

Operation

It remains concealed usually within the ceiling or floor space and is activated from the fire detection system and horizontally closes automatically. The leading edge of the curtain fabric has a special pre-tensioned support bar spanning the opening which runs in the side channels where the curtain fabric is retained. On alarm activation, the barrier is driven by tubular motors to the closed positions using steel pull straps which are concealed in the side guides.

Test is performed by a simple key switch operator. The system is reset manually by pressing the reset button on the control panel. Automatic reset is available.
