Dorgard is the easy, safe and legal solution to holding fire doors open, while automatically closing on the sound of an alarm. You often see doors held open using fire extinguishers or chairs but this is breaking the law.

Dorgard's are fully automatic and will release a fire door when an alarm is heard. Being completely wire free and battery operated installation and maintenance is easy, quick and non disruptive.
Installation is easy, quick and non-disruptive. The Dorgard 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.
How Do Dorgards work?
Dorgard is a complete wireless solution as it is a battery operated self-contained device. The Dorgard constantly listens for a sound above 65 db. Once the fire alarm sounds, the Dorgard will pick up the noise and after approximately 14 seconds, the Dorgard will release the fire door. The Dorgard is also capable of automatically releasing doors at night for maximum protection.
How does the Dorgard Automatically Release the Doors?
Although the Dorgard can be used to hold open a fire door 24 hours a day, it is not ideal at night. The Dorgard has an Automatic Night Time Release feature. Dorgard has an internal clock, which allows the user to set a time for the Dorgard to automatically release a fire door. The Dorgard will then not operate as a hold open device until the next morning at a time set by the user. This allows the Dorgard to provide maximum protection 24 hours a day.
To hold the door open
Open the door to the required 'hold open' position, or open fully against the bump stop of the floor plate (if fitted). Stand sideways to the door. Press the black knob on top of the Dorgard down using your foot. Greater foot pressure may be needed depending upon force from the door closer or the type of floor surface. Whilst depressing the black knob pull the door gently in the direction of closing. Remove your foot and let go of the door.
To release Dorgard manually
Lightly kick the black knob toward the door. Or push the door in the direction of opening. Dorgard can only be released by kicking the black plunger knob if a floor plate is installed. Dorgard Applications
Dorgard is ideally suited to hotels, office buildings, guest houses and any buildings where hard wiring door release mechanisms is not an option. Dorgard is easy to install and will help you meet the fire regulations without having to fit an expensive and intrusive alternative. Dorgard installs in under 5 minutes!
