DESCRIPTION
TRIASMOKE EV is an Automatic Smoke Curtain that in the case of fire, limits and controls the movement of smoke, with classification DA, besides allowing evacuation of people in the case of fire.
The curtain is composed of fibreglass fabric with polyurethane coating on both sides seamed with high resistant kevlar wire and fixed to a steel roller of 78 mm in diameter; galvanized steel headbox. Stripped textile shape for passing through.
The system is driven by a 24 V tubular motor and controlled by an electronic board, CRM (Control and Regulation for Motor) with a special Gravity Fail-Safe System. The 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 autonomy up to 6 hours exists in all control panels.
Tested and approved according to the European Standard UNE EN 12101-1 and with CE Marking.
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 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. When the curtain is completely deployed the users can pass through it keeping smoke protection. 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 for up to 6 hours thanks to battery backup system.
FABRIC
The fibreglass 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 high resistance Kevlar wire.
