Fireproof Rolling Shutters

FIRE PROOF ROLLING SHUTTER

Fire proof rolling shutter BLOCKSHUTTER EI120 is a system that guarantee integrity and thermic insulationfor 120 minutes. It is composed of horizontal galvanized steel elements, 110 mm height , with a thickness of 50 mm and a weight of 42 Kg/mq; the elements are securely hoocked toghether and fastened on the side with steel endlocks to prevent slipping and guarantee the uniform element descent. The bottom element is covered with a thick U bead with thermoexpandig gasket The slats are infilled with three layer of highly performing silicate material that guarantee after two hours of fire exposition in according with EN 1634-1 fire test, the avarage temperature measured lower than 90°C on not exposed side.

BLOCKSHUTTER EI120 is certified for RESISTANCE TO WIND LOAD CLASS 2 in according to EN 13241-1 and CE MARKED in according to EN 16034:2014, EN 13241:2003 + A2:2016

INSTALLATION

Front wall fixation on the wall with threaded rods da Ø12, 450 Kg/m3 minimum wall density allow, 200 mm thickness.

On request: automatic operation, casing and Ral coating

SUPPORT SYSTEM

The support system consist of two sturdy steel brackets to which is inserted a support shaft of 323 mm diameter on which the rolling shutter is rolled. A pression shaft is positioned on the internal side, in the external side intstead, there is a tubolar with thermo expanding gaskets to seal and contain the flames.
The frontal protection consist in a labyrint system that joint the frontal tubolar to the door leaf.

AUTOMATION FOR BLOCKSHUTTER EI120

BLOCKSHUTTER EI120 is normally supply with a 400V three phase chain wheel drive – IP54 with Gravity fail safe sistem, that guarantee a controlled speed decent, even in case of power failure. It is mandatory for the Gravity fail safe sistem, to install an acustic and visual signal in accordig with EN 12604. A back up battery is integrated in the control panel and in case of power failure, assure continuity of the power supply to the magnetic brake to avoid an unespected leaf’s descent.

The control panel is arranged for connection to the fire alarm and smoke or temperature detection system.
An built-in keyboard with up/down/stop inputs is provided.
A 400 V three-phase drive with manual chain operation can be supplied as an alternative, with this motor type is mandatory to have an UPS (borne to the Customer) for the open manouvre when the alarm activation occur.
The control panel (without back up battery) is arranged for connection to the fire alarm, smoke or temperature detection system. An built-in keyboard with up/down/stop inputs is provided
