BACH FIRE E120 is an automatic fire curtain that limits and controls fire. It has E120 classification. The curtain consists of: fiberglass fabric with polyurethane coating on both sides, sewn with reinforced steel wire and it is attached to a steel roller with a diameter of 78mm; the upper box, side guides and lower bar elements are made of galvanized steel. The entire system is controlled by a 24 Vdc tubular motor which is 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 system) with an autonomy of up to 6 hours exists in all control panels. Tested and approved according to European standards UNE EN 1634-1 and UNE EN 1363-1.


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. 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.
