FR-GD650S Fire Door Retaining Magnet

The FR-GD650S Fire Door Retaining Magnet is a fire-rated electromagnetic door holder designed to safely hold fire doors open during normal operation and automatically release them when the connected fire alarm system is activated. Also known as a fire door retainer, fire door hold open magnet or electromagnetic door holder, the FR-GD650S provides a reliable solution for controlled fire door hold-open applications.

Designed for integration with fire alarm systems, the FR-GD650S allows compatible fire doors to remain open for convenience and accessibility. When power is removed following activation of the fire alarm system, the magnet releases the door, allowing the door closer to automatically close it.

Manufactured from stainless steel, the FR-GD650S has been tested to BS EN 1155 for electrically powered hold-open devices and fire tested to BS EN 1634-1. It is suitable for compatible FD30 and FD60 fire doors and holds a 1-hour UK fire certificate. An integrated override switch allows the retained door to be released locally when required.
