The FireMaster® Plus NVS™ Horizontal fire curtain provides the same function and benefits as the FireMaster® NVS™ Horizontal with the added performance of creating an insulating zone. You would use the FireMaster® Plus NVS™ Horizontal where you need to protect means of escape or if there is close proximity of combustible items.
It remains concealed usually within the ceiling or floor space and is activated from the fire detection system and horizontally closes automatically.
Three types of horizontal curtain; the Mini Simplex, 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 6m wide with a 10m draw.
Maxi Simplex and Maxi Duplex models are required where the width exceeds 6 meters and up to 9 meters.
Metalwork is zinc coated mild steel. This can be painted on site or powder coated to DULUX or RAL colours.
Test / Reset
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.
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.
The curtain material is a satin weave fibreglass fabric with a silver polyurethane coating on both sides and integral stainless wire. It is 0.54mm thick, and weighs approximately 690g/m² in its finished form.
