The steel spraying fire-rated roller shutter consists of a roller
shutter and a spraying system. It features water-saving, spraying
and cooling effectively with a bit of water. The mist can eliminate
the smoke as well.
Structure: contains two parts.
One is the electric steel fire-rated roller shutter, made up of a
curtain, two guide rails, a bottom rail, a gearing, a motor, a
control box, a , a metal fuse and a top box.
The other is the spraying system, made up of a water supply pipe, a
pipeline with sprinklers and a control box.
Principles of Control:
The roller shutter is operated by electrical control. As per Fire
Safety Rules, there are three ways to control the electric box.
First one is sensor control. When the smoke sensor gives a signal
to the box, the box will give a sound and light alarm and get the
curtain lower to the middle height. When the temperature sensor
gives a signal to the box, it will get the curtain lower to the
ground. Second one is fall-suspend-fall. When the curtain gets to
the middle height, it will stop for some time to let survivors to
escape and then continue to fall to the ground. Third one is fall
without stop. Once one of the sensors gives a signal, the curtain
will fall to the ground.
Principles of Spraying Control System:
When the control box receives the fire signal and the roller
shutter shuts down, it will send a signal to water control to turn
on the ball valve. Or if the temperature rises to 68Æ’, the temperature-sensitive glass ball in
the water control box will break in order to activate the sprayer.
Meanwhile, the activation signal will be sent to the control box
which will shut down the roller shutter and be sent to the Fire
Control Center whose pump supplies water for sprayer.
Application: Fire escape, basement garage close to
water supply
