DESCRIPTION

BACHFIRE UL10D is an Automatic Fire Curtain that in the case of fire, limits and
controls the fire, with classification UL 10D 180 minutes.
The curtain is composed of: fibreglass fabric with polyurethane coating on both
sides seamed with reinforced steel wire and fixed to a steel roller of 78mm in
diameter; galvanized steel elements as headbox, side guides and bottom bar.
The system is driven by a 24 V tubular motor and controlled by an electronic
board, the CRM (Control and Regulation for Motor) with special gravity fail-safe
system.
The control panel for automatic curtains (CBM), with a nominal input voltage of
115 V or 220 V and an output voltage of 24 V.
Uninterruptible Power Supply (UPS System) with autonomy for up to 6 hours
exists in all control panels.
Tested and approved according to UL10D:2014 “Standard for Fire Tests of Fire
Protective Curtain Assemblies” with APF certificate.

OPERATION

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 Control Panel (CBM), receives the signal alarm, and the automatic curtain deploys automatically, with the controlled and safe constant speed of descent even following total power loss on all curtains. If there is a false alarm the curtains return to the stand-by position automatically after resetting of alarm from the main Fire Management System. In case of main power loss, the curtain will remain fully retracted for up to 6 hours thanks to the battery backup system.
