Statement
Electromagnetic Door Holders are suitable for and mostly found in large-scale buildings like hospitals, hotels,department stores, etc.
They release doors and prevent the spreading of smoke out of a confined space in case of fire.
The power source is supplied by the fire fighting system either 24 VDC (or 12VDC special order). The door holder is a Fail-safe device which
automatically cuts off the power and closes the fire door when the fire fighting system detects a fire.
The door can also be instantly released manually by using the release button.
