24v fire door holders are low-voltage devices designed to help delay the spread of fire through a building. They are typically an electromagnetic device which holds fire doors open and then automatically releases them when a fire alarm is activated, allowing the door to close and seal the area, helping to contain the fire and smoke. They require a 24Vdc power supply to operate and can be interfaced to most conventional and addressable fire alarm systems.
