BACHFIRE E 120 is an Automatic Fire Curtain that in the case of fire, limits and
controls the fire, with classification E 120.
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 78 mm of
diameter. Galvanized steel elements as headbox, side guides and bottom bar.
All the system is driven by a 24 V tubular motor and controlled by an electronic
board, 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 output voltage of 24 V.
Uninterruptible Power Supply (UPS System) with an autonomy up to 6 hours
exists in all control panels.
Tested in accordance with EN 1634-1 and classified in accordance with EN 13501-2, it also complies with the conditions and procedures for CE Marking provided for EN 16034 standards.

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 stand-by position automatically after reset of alarm from the main
Fire Management Systems. In case of main power loss, the curtain will remain
fully retracted thanks to the battery backup system.

The fibreglass fabric resists up to 1100ºC. The polyurethane coating on both
sides guarantees mechanical stability when handling the fabric not only in
the sewing process but also during the installation. All seams are done with
reinforced stainless steel wires with a coating of Kevlar.
