Description

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.
