SUPERFIRE Z EI120 is an Automatic Fire Curtain that in the case of fire, limits and controls the fire, reduces not only radiation emission but also heat transfer creating isolation from the fabric so that protection of people and goods is maximized, with classification EI120.
The curtain is composed by two fabrics, one folds like a concertina and one flat fabric. They are both fiberglass fabric coated on both sides and seamed with reinforced steel wire and fixed to a steel roller of 78mm of diameter; galvanized steel elements as head-box, side guides and bottom bar; irrigation system on the flat fabric side.
All the system is driven by a 24Vdc tubular motor and controlled by an electronic board, BACH’s CRM (Control and Regulation for Motor) with special gravity fail safe system.
The control panel for automatic curtains (CBM), with 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 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 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. A solenoid valve connected to BACH´s control panel can activate the irrigation system. If there is a false alarm the curtains return to stand-by position after manual reseting 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.

The fiberglass fabric has low radiation, high isolation properties and resists up to 1100ºC. All seams are done with reinforced stainless steel wires with a coating of Kevlar.

Galvanized Steel head-box 1,2mm thickness with different possibilities to adapt to different architectural spaces, and maintenance requirements.
Dimensions of the head-box varies depending on width and height of the curtain.

Galvanized Steel from 1,5 to 3mm thickness and different dimensions depending on width and height of the curtain.

Galvanized Steel of 1,5mm thickness and 78mm diameter. Special slide system for fixing the fabric.

Galvanized Steel of 1,5mm thickness.

A solenoid valve connected to BACH´s control panel can activate the irrigation system with a delay of 3 minutes for standard. As an option, the solenoid valve can be dependent on a thermal sensor in order to avoid water spray in false alarm conditions, so even if there is a fire alarm the irrigation system doesn´t work until the sensor reaches 77ºC. In this case and for safety reasons, the irrigation system will not be activated until this 3 conditions meet together, 1st – fire alarm and 2nd – Three minutes delay and 3rd – Thermal Sensor above 77ºC. The number of sprinklers depends on the area of each system. The fluid conditions are the following:

Water Flow ≥ 5,5 l/min/m²
Pressure ≥ 2 bar

Irrigation system hidden inside the headbox.
Thermal sensor electronic sensor activates solenoid at 77ºC (for irrigation).
RAL coating head-box, side guides, bottom bar.
Stainless steel elements head-box, side guides, bottom bar, screws, rivets.
Headbox customized set-up for specific architectural or special operational requirements.
Side guides customized set-up for specific architectural or special operational requirements.
Bottom bar aluminum profile painted RAL 9003 (white) for using with false ceiling accessories.
False ceiling accessories aluminum profiles painted RAL9003 to hide head-box over false ceiling.
Electric motor special 24Vdc motors up to 80Nm without CRM; Special 230Vac motors up to 120Nm without CRM.
CBM control panel special designs up to 48 motors in one control panel, additional information output, micro switches, communication with other devices, special battery backup, possibility of delaying curtain deployment.
Escape button pushing this button the curtain goes up and the user can escape through the opening, the curtain deploys 30s later automatically.

Note: other requirements and customized solutions on demand.
