BACHFIRE Z is an Automatic Fire Curtain that in the case of fire, limits and
controls the fire, with classification E120 and EW 20. This system can be adapted
to irregular geometric perimeters open or closed, in order to avoid vertical beams.
The curtain is composed of fibreglass fabric with polyurethane coating on both
sides seamed with reinforced steel wire and fixed to a 2 mm plate inside the
headbox and to the bottom bar. Galvanized steel elements such as headbox,
side guides and bottom bar.
All the system is driven by at least one 230 V tubular motor with special gravity
fail-safe system.
The control panel for automatic curtains (CBM), has a nominal input voltage of
115 V / 220 V and an output voltage of 230 V / 24 V.
Uninterruptible Power Supply (UPS System) with autonomy for up to 6 hours
exists in all control panels.
Tested in accordance with EN 1634-1 and classified in accordance with EN 13501-2.

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 the 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 1,100ºC sewed as a concertina shape. 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.
