BACHFIRE EW 120 is an Automatic Fire Curtain with EW 120 classification that,
in the case of a fire, limits and controls the fire and, reduces radiation emission
less than 15 kW/m2.K at 1m of distance from the fabric.
The curtain is composed of fibreglass fabric with aluminum foil on both sides
seamed with reinforced steel wire and fixed to a steel roller of 78 mm in diameter.
Galvanized steel elements such as headbox, side guides and bottom bar.
The entire system is driven by a 24V tubular motor and controlled by an electronic
board. Built-in CRM (Control and Regulation for Engine) with special gravity failsafe
system. 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 of up to 6 hours available 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 a 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 the 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.

The fibreglass fabric has low radiation properties and resists up to 1,100ºC.
Radiation is less than 15 kW/m2.K at 1 meter distance. All seams are done with reinforced stainless steel wires with a coating of Kevlar.

Galvanized Steel headbox 1.2 mm thickness with different possibilities to adapt to different architectural spaces, and maintenance requirements.
Dimensions of the headbox vary depending on the width and height of the curtain.

Galvanized Steel from 1.5 to 3 mm thickness and different dimensions depending on width and height of the curtain.
