Product Operation

Electromagnets are typically used with fire alarm systems.

Doors are held open in the non-alarm condition. When the fire alarm panel enters the alarm condition, power to the electromagnets is removed, the doors close under door closer control, and function as a manual door.

When the fire alarm panel returns to the non-alarm condition, power is reapplied to the electromagnets and the doors can be held open again.
