Dorgard Fire Door Retainer (White) (DG1328W)

How does it work?

Dorgard is a device designed to safely hold open a fire door and automatically release the fire doors upon the sound of a fire alarm. It can be used to hold the fire door open in any position.

Unlike electro-magnetic retainers (EMR), Dorgard requires no wiring as it is battery operated and self-contained. Installation is easy, quick and non-disruptive. It is affixed to your fire door with four screws and takes approximately 5 minutes to install. Once you have inserted two C-size batteries (supplied), Dorgard is ready for duty.

When Dorgard is holding open a fire door it listens for a continuous fire alarm sound level of over 65 decibels. After approximately 14 seconds it will release, allowing the fire door to close under the pressure of the overhead door closure.

To hold the door open

1. Open the door to the required ‘hold open’ position, or open fully against the bump stop of the floor plate (if fitted).
2. Stand sideways to the door.
3. Press the black knob down using your foot. Greater foot pressure may be needed depending upon force from the door closer or the type of floor surface.
4. Whilst depressing the black knob pull the door gently in the direction of closing.
5. Remove your foot and let go of the door.

To release Dorgard manually

1. Lightly kick the black knob toward the door.
2. Or push the door in the direction of opening. Dorgard can only be released by kicking the black plunger knob if a floorplate is installed.
