MARC-VRo Window curtain

Version with fuse element

In case of fire risk, the fuse element is triggered (the element is heated up to temp. of 74°C). This solution requires no additional power supply. After releasing the lock with fuse element, the door goes down under its own weight. In order to control the speed of free lowering of the gate, a speed control device is installed. A crank is used to lift the gate.

Version with tubular drive

Opening and closing of the rolling curtain is carried out by a tubular motor 24V DC.  In case of fire risk, the fire-fighting central unit activates the motor and the door closes the passage between the fire zones. When using a tubular motor, it is necessary to use control system cooperating with the local fire-protection control unit or local Fire Alarm System.
