How it works
In its resting position, this fully automatic liquid barrier is located above the door or gate opening. It is held at its upper position by pneumatic cylinders.
When switching on the fire alarm control unit, liquid sensor (optional), power failure or by simply manually pressing the control button (emergency button), the barrier closes slowly. AWhen the barrier is in active position, it is automatically locked by two pneumatic quick release clamps at the bottom and pressed in liquid-tight.
Unlocking the pneumatic quick release and returning the barrier to above the door or gate at rest position is done pneumatically..
