GD830S / FR-GD830S Fire Door Retaining Magnet
The GD830S Series Door Retaining Magnet is a electromagnetic door holder designed to safely hold open fire doors during normal operation and automatically release them when connected fire alarm systems activate. Also known as a fire door retainer, fire door hold open magnet, fire door holder, fire door hold open device, door hold open magnet, or electromagnetic door holder, the GD830S provides a reliable solution for fire door management in commercial, educational, healthcare, and public sector buildings.
Designed for integration with fire alarm systems, the GD830S allows fire doors to remain open for convenience and accessibility. Upon activation of the fire alarm system, power is removed from the magnet, allowing the door closer to automatically close the fire door and help prevent the spread of smoke and fire throughout the building.
Manufactured from durable stainless steel, the GD830S Series provides dependable performance and long-term reliability. The FR-GD830S-12 and FR-GD830S-24 fire-rated versions have been tested to BS EN 1155 for electrically powered hold-open devices and fire tested to BS EN 1634-1. They are suitable for compatible FD30 and FD60 fire doors and hold a 1-hour UK fire certificate. All models include an integrated override switch for local release of the retained door when required.
