GD830F-12 / GD830F-24 Door Retaining Magnet

The GD830F-12 / GD830F-24 Floor Mounted Door Retaining Magnets are electromagnetic door holders designed to safely hold doors open during normal operation and automatically release them when the connected fire alarm or door control system is activated. Also known as a door retaining magnet, door hold open magnet, door holder, door hold open device or electromagnetic door holder, the GD830F provides a reliable solution for controlled door hold-open applications in commercial, educational, healthcare and public sector buildings.

Designed for integration with fire alarm and door control systems, the GD830F allows doors to remain open for convenience and accessibility. When power is removed from the magnet, the retained door is released, allowing the fitted door closer to automatically close the door.

Manufactured from durable stainless steel, the GD830F Series provides dependable performance and long-term reliability. Available in dedicated 12VDC and 24VDC versions, both models include an integrated override switch for local release of the retained door when required.
