FAQ

Frequently Asked Questions

Why install Fire & Smoke curtains?
Fire & Smoke kill! The curtains assist in the evacuation of people. They prevent smoke logging and retard the lateral spread of fire, thus saving lives. The curtain fabric is manufactured from a specially formulated micronised aluminium polymer, reinforced with stainless steel wire which provides a heat reflective surface.

How do they operate?
The curtain in it’s dormant position is concealed in a roof void. On a command signal from an alarm system the curtain will descend creating a smoke “compartment”

What is gravity failsafe?
In the event of a total power failure the Fire & Smoke curtain will still deploy to it’s operational position.

What does the control panel do?
Operates and monitors the smoke/fire curtains in various situations. i.e. speed of descent, level of descent, powered or non-powered. Status relays indicate power and operational status. A master control panel will operate up to 32 slave panels/curtains.

What is SHEVS?
SHEVS is an acronym for smoke, heat, exhaust & ventilation systems. The purpose of SHEVS is to create a fire “compartment” bounded by a construction having a specified Fire/Smoke resistance to allow the evacuation of a building.

Why install a Fire curtain as opposed to a Steel Fire Shutter?
Fire Curtains contain heat more effectively than steel shutters. Due to their compact design, the head box is considerably smaller than on a traditional steel shutter, which means that they can be installed into a restricted ceiling void. Due to their size and ease of fitting, fire and smoke curtains are suitable for existing building refurbishments and fit-outs.
