BACHFIRE Z E120 is an Automatic Fire Curtain that in the case of fire, limits and controls the fire, with classification E120. This system can be adapted to irregular geometric perimeters open or close ones in order to avoid vertical beams.
The curtain is composed by: fiberglass fabric with polyurethane coating on both sides seamed with reinforced steel wire and fixed to a 2mm plate inside head-box and to the bottom bar; galvanized steel elements as head-box, side guides and bottom bar. All the system is driven by at least with one 230V tubular motor with special gravity fail safe system. The control panel for automatic curtains (CBM), has nominal input voltage of 115Vac or 220Vac and output voltage of 230V/24V. 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.
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 are side guides the system must by reset manually. 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.
The fiberglass fabric resists up to 1100ºC sewed as a concertina shape. The polyurethane coating on both sides guarantees mechanical stability when handling the fabric not only in the sewing process but also during the installation. All seams are done with reinforced stainless steel wires with a coating of Kevlar.
