Fire-protection curtain gates of Marc-Ok plus type are designed to separate fire zones in accordance with binding fire regulations.
They are used mainly in buildings with high aesthetic demands - public buildings and shopping centres. They are flexible separations of fire zones and their low installation requirements make them the ideal solution for places with very little space around the wall opening.

Principle of operation
The curtain jacket consists of three layers: two identical external layers and an internal middle layer.
The total thickness of the jacket is ca. 10 mm. From one side, the jacket is fixed to the coiling shaft of the curtain made of f89 steel pipe (depending on the gate dimensions). In the bottom part of the outer jacket, the layers are interconnected by another material - each external layer has a weight fixed to it.

• Fire Signalling Central Unit
- compliant with the PN-EN 54-2:2002 standard, located near the gate;
- power supply voltage230V AC 50Hz;
- built-in external batteries, which hold the gate in the open position for a specified time after a power failure (if there is no fire hazard)
- monitoring of the fire sensor line, FAS, signallers.
• Vic-0701 drive: 24V DC power supply closing type: electrical
• Process switch
• Fire sensor
• Optical-acoustic signaller
• Extra paid additional protections:
