DESCRIPTION

BACHFIRE EW120 is an Automatic Fire Curtain that in the case of fire, limits and controls the fire, reduces radiation emission less than 15 kW/m2.K at 1m of distance from the fabric, with classification EW120. The curtain is composed by: fiberglass fabric with Aluminum foil on both sides seamed with reinforced steel wire and fixed to a steel roller of 78mm of diameter; galvanized steel elements as head-box, side guides and bottom bar. All the system is driven by a 24Vdc tubular motor and controlled by an electronic board, BACH’s CRM (Control and Regulation for Motor) with special gravity fail safe system. The control panel for automatic curtains (CBM), with nominal input voltage of 115Vac or 220Vac and output voltage of 24Vdc. Uninterruptible Power Supply (UPS System) with autonomy up to 6 hours exists in all control panels.

Tested and approved according to the European Standards UNE EN 1634-1 and UNE EN 1363-1.

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 BACH’s Control Panel (CBM), receives the signal alarm, and the automatic curtain deploys automatically, with controlled and safe constant speed of descent even following total power loss on all curtains. If there is a false alarm the curtains return to stand-by position automatically after reset of alarm from main Fire Management Systems. In case of main power loss, the curtain will remain fully retracted up to 6 hours thanks to BACH’s battery back-up system.

FABRIC

The fiberglass fabric has low radiation properties and resists up to 1100ºC. Radiation is less than 15 kW/m².K at 1 meter distance. All seams are done with reinforced stainless steel wires with a coating of Kevlar.
