MARC-R Sideways sliding doors

Principle of operation

In the basic version, the gate wing is closed gravitationally by a counterweight. The door is kept in the open position by an electromagnetic door holder connected to the central fire protection unit. In case of fire risk, the fire-fighting central unit releases the electromagnetic gate holder and the gate wing closes the passage between the fire zones. The gate is opened manually or automatically by an electromechanical drive. It is possible to use DC drive powered by 24V - in such case the door is provided without the counterweight and its opening/closing is carried out by the drive.
