Lockwood Extended Wall Mount Fire Door Holder (EMH50-EWM)

The Lockwood EMH50-EWM extended wall mount fire door holder provides 23kg of magnetic holding force with selectable 12VDC or 24VDC operation. Its extended wall bracket gives a 105mm projection for installations needing additional clearance.

Controlled hold-open and fail-safe release

The electromagnet keeps a door open while powered. When power is removed, it releases the door so a suitable door closer can close it. For fire-door applications, connect it to an appropriately designed fire detection and release system. An onboard emergency release/test button enables manual release and routine checks.

Technical specifications

Applications and installation

Suitable for single and double fire doors where the installation requires controlled hold-open and release. It can also hold non-fire doors open in settings such as hospitals and cinemas. A compatible DC power supply is required separately. Confirm the mounting clearance, door closer, release controls and system compatibility before ordering.

Use the model-specific installation instructions for wiring and voltage selection. Fire-door suitability depends on the complete door assembly and system design; the holder must allow the door to close when released.
