Superfire
DESCRIPTION
SUPERFIRE is an Automatic Fire Curtain that in the case of fire, limits and controls the fire, reduces not only radiation emission but also heat transfer creating isolation from the fabric so that protection of people and goods is maximized, with classification EI 120.
The curtain is composed of fibreglass fabric coated on both sides and seamed with reinforced steel wire and fixed to a steel roller of 78 mm in diameter, galvanized steel elements as headbox, side guides and bottom bar, irrigation system for the opposite side of the fire.
All of the systems are driven by a 24 V tubular motor and controlled by an electronic board, the CRM (Control and Regulation for Motor) with a special Gravity Fail-Safe System.
The control panel for automatic curtains (CBM), with a nominal input voltage of 115 V or 220 V and an output voltage of 24 V.
Uninterruptible Power Supply (UPS System) with autonomy for up to 6 hours exists in all control panels.
Tested in accordance with EN 1634-1 and classified in accordance with EN 13501-2.
OPERATION
The system can be activated by a SHEV, fire alarm contact, internal fire and smoke detection devices, or manual emergency buttons. In the event of a fire, the Control Panel (CBM) receives the signal alarm and the automatic curtain deploys automatically, with a controlled and safe constant speed of descent, even following total power loss on all curtains. A solenoid valve connected to the control panel can activate the irrigation system. If there is a false alarm the curtains return to the stand-by position automatically after resetting the alarm from the main Fire Management Systems. In case of main power loss, the curtain will remain fully retracted for up to 6 hours thanks to the battery backup system.
FABRIC
The fibreglass fabric has low radiation, high isolation properties and resists up to 1,100ºC. All seams are done with reinforced stainless steel wires with a coating of Kevlar.
IRRIGATION SYSTEM
A solenoid valve connected to the control panel can activate the irrigation system with a delay of 3 minutes for standard. As an option, the solenoid valve can be dependent on a thermal sensor in order to avoid water spray in false alarm conditions, so even if there is a fire alarm the irrigation system doesn´t work until the sensor reaches 77ºC. In this case and for safety reasons, the irrigation system will not be activated until the following conditions meet together:
01 Fire alarm;
02 3 minutes delay;
03 Thermal sensor above 77ºC.
The number of sprinklers depends on the area of each system. The water conditions are the following:
– Water flow: >= 6,5 L/min/m²
– Pressure >= 3,2 Bar
