Description
The system can be activated by a smoke exhaust system (SHEV), a fire alarm contact, internal fire and smoke detectors or manually operated emergency buttons. In the event of a fire, the control panel (CBM) receives an alarm signal and the automatic curtain automatically deploys, with a controlled and safe constant lowering speed, even after a complete power failure of all curtains. In the event of a false alarm, the curtains automatically return to the standby state when the alarm is reset by the fire control system. In the event of a mains power failure, the curtain remains fully retracted thanks to the battery-based backup power system.
The entire system is driven by a 24 V tubular motor and is controlled by an electronic board, CRM (Motor Control System) with a Special Gravity Fail-Safe System. The device has an automatic curtain control panel (CBM) with a nominal input voltage of 115 V or 220 V and an output voltage of 24 V. All control panels are equipped with an uninterruptible power supply (UPS system) with an autonomous power supply duration of up to 6 hours.
