The curtain consists of: fiberglass fabric with polyurethane coating on both sides sewn with high-strength Kevlar wire and attached to a steel roller with a diameter of 78mm; the upper box is of galvanized steel, a strip-shaped textile for passage; The entire system is controlled by a 24 Vdc tubular motor, controlled by an electronic board, BACH's CRM (Motor Control and Management) with a special gravity system in case of failure. Automatic curtain control panel (CBM), with a nominal input voltage of 115 Vac or 220 Vac and an output voltage of 24 Vdc. An uninterruptible power supply (UPS) with an autonomy of up to 6 hours exists in all control panels. Correction and approval in accordance with European standards UNE EN 12101-1 and CE mark.


The system can be activated via SHEV, fire alarm contact, built-in fire and smoke detection devices, or manual emergency buttons. In the event of a fire, the BACH control panel (CBM) receives a signal alarm, and the automatic curtain is automatically activated, at a controlled and safe rate of descent even after a complete loss of power on all curtains. When the curtain is fully lowered, users can pass through it, while maintaining smoke protection. In the event of a false alarm, the curtain automatically returns to sleep mode after resetting the alarm from the main fire control system. In the event of a power failure, the curtains will remain fully raised for up to 6 hours thanks to BACH's battery backup system.
