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.
