Automatic Smoke Curtain:
BACHSMOKE Z is an Automatic Smoke Curtain that in the case of fire, limits and controls the movement of smoke, with classification D120. This system can be adapted to irregular geometric perimeters open or closed ones in order to avoid vertical beams.
The curtain is composed by:
- fiberglass fabric with polyurethane coating on both sides seamed with reinforced steel wire and fixed to a 2mm plate inside head-box and to the bottom bar
- galvanized steel elements as head-box, and bottom bar
All the system is driven by at least one 24Vdc tubular motor with special gravity fail safe system.
The control panel for automatic curtains (CBM), has nominal input voltage of 115Vac or 220Vac and output voltage of 24Vdc.
Uninterruptible Power Supply (UPS System) with autonomy up to 6 hours exists in all control panels.
Tested and approved according to the European Standards UNE EN 1634-1 y UNE EN 1363-1.
Description of 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, with 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 main Fire Management Systems.
In case of main power loss, the curtain will remain fully retracted up to 6 hours thanks to BACH's battery back-up system.
Usually installed in logistics centers, industries, nuclear power plants, agri-food indutries, shops, theaters, sports centers, etc.
