DESCRIPTION
BACHSMOKE H is a horizontal automatic smoke curtain with DA and DH 120
classification that, in case of a fire, limits and controls the smoke.
The curtain is made from fiberglass fabric, with polyurethane coating on both
sides, seamed with reinforced steel wire, and fixed to two steel rollers of 78 mm
in diameter. It also includes galvanized steel elements such as headbox, side
guides, and bottom bar.
All the system is driven by two 24 V tubular motors, on opposite sides. The control
panel for automatic curtains (CBM) has a nominal input voltage of 115 V or 220
V and an output voltage of 24 V.
A UPS System (Uninterruptible Power Supply) with an autonomy of up to 6
hours in all control panels.
Tested and approved according to the European Standard UNE EN 12101-1 and

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 BACH’s Control Panel (CBM), receives the signal alarm, and the automatic curtain deploys automatically, at constant speed. If there is a false alarm the curtains return to stand-by position automatically after reset of alarm from main Fire Management Systems. In case of main power loss, the curtain will be ready to be activated with batteries at least during the next 24h.
FABRIC
The fiberglass fabric resists up to 600ºC. 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.
