What activates the fire curtain?
Temperature increase at the sensor of 15°F (9°C) or more per minute, activates the rate-of-rise feature; self restoring. Fixed temperature: If temperature of the center disk rises to the sensor’s rated temperature, the fixed temperature element activates.
How does a smoke curtain work?
Smoke curtains remain invisibly retracted until activated by an alarm, detector signal or manual switch. This allows the safe evacuation of people from buildings, whilst reducing fire damage by preventing smoke logging, which enables fire-fighting, reduces temperatures and ultimately delays the spread of fire.
What is the difference between fire curtain and smoke curtain?
Smoke Curtains don’t descend to ground level (ceiling to floor). They are generally set above head height, so as not to interfere with the means of escape. A fire curtain, on the other hand, is used to provide fire separation between two spaces.
What are smoke curtains made of?
Draft curtains like Smoke Guard’s SG Draft are static smoke curtains that are a cost-effective, ideal solution for large spaces. This durable curtain is made of a glass filament fabric that is heat- and fire-resistant.
What is a smoke baffle?
The purpose of smoke baffles is to contain smoke during a building fire and prevent the smoke from spreading to other areas. Smoke baffles must be flame- and fire-resistant for a minimum of one hour and can help give building occupants time to exit a building during a fire.
How does a smoke screen work?
Very large or sustained smoke screens are produced by a smoke generator. This machine heats a volatile material (typically oil or an oil based mixture) to evaporate it, then mixes the vapor with cool external air at a controlled rate so it condenses to a mist with a controlled droplet size.
What is smoke barrier?
Smoke barriers are used to subdivide building spaces into smoke compartments. They restrict the passage of smoke and therefore through-penetrations must be sealed with a material capable of restricting the transfer of smoke.
What is a smoke shutter?
SmokeStop is an automatically deploying smoke curtain designed to control the spread of smoke in a building. The SmokeStop Active Smoke Barrier is an automatic smoke curtain which comprises of technologically advanced fire-resistant fabric roller barriers encased in a compact steel housing.
What is smoke screen made of?
Calcium phosphide is used to produce smoke screens.
Does smoking block IR?
Soot particles in smoke effectively block visible light, but allow infrared radiation to pass through, letting firefighters or other first responders navigate through smoke-filled environments.
