Description

No. Dorgard listens for a continuous sound and will verify the alarm over a 20 second period and then release the fire door. School bells generally last for a couple of seconds so this shouldn’t affect your Dorgard. - Should I use a particular type of battery and can I use rechargeable ones? These door holders can be powered by batteries, from the mains, or from nearby power supply units (PSU) rated at 12V or 24V DC. It is generally recommended to install them at the top of the door to prevent warping caused by the door closer pulling against the electromagnet. Battery-powered versions typically use an acoustic sensor to listen for an alarm sounder while wired models will often be connected directly to the fire alarm panel. The Agrippa holder uses ‘listen and learn’ technology to record the specific sound of the building’s alarm, ensuring the doors will close upon hearing this sound, rather than reacting to loud noises such as school children or vacuum cleaners. However, as with all sound activated devices, they may be triggered in an extremely noisy environment. In this case, the Salamander radio controlled system should be considered. The Agrippa device can be fitted to internal fire doors in less than 10 minutes, view our online installation videos here.

The holder is recognised by UK Fire and Rescue Services and the London Fire Brigade, suitable for installation to BS 7273-4 Standard Actuation (Category B) and conforms to EN1155 and is CE marked. All versions feature a low battery indicator to alert you to the need for replacement Duracell Plus Batteries - AA, AAA, C, D, and PP3

How does Dorgard work?

Fire door retainers (also called fire door holders) allow occupants to hold fire doors open in a legal and safe manner, removing the temptation to wedge the doors open. These devices hold the doors open in the day-to-day running of the building but will release the fire doors if there is a fire, allowing the fire door closers to do their job. Easy-to-install in under 5 minutes, simply fix to your fire door with 4 screws and insert the batteries – no wiring or mains power required Instead of installing additional components to fire doors, there are door closers available which have retainer features built-in for convenience, such as Freedor They may have the ability to hold a door open at certain angles (Hold Open models) or to temporarily disengage their mechanical components so that fire doors feel as light as normal doors (Free Swing models). Both models require power to work, either wired into a power supply or fitted with batteries, and will "fail safe" during a power failure – meaning that electricity is used to disengage the closing force and by default they will try to keep the door closed when no power is supplied.

Fire doors are an important part of any building's fire safety strategy as they enable movement throughout a building while stopping the spread of fire to allow occupants enough time to evacuate safely. However, fire doors can only function if they are closed or close automatically if a fire occurs. This is the reason why it is dangerous and illegal to hold fire doors open with a wedge or extinguisher. When equipped with a Dorgard, fire doors can be held open at any angle by simply pressing the plunger down with your foot, and nudging the top of the plunger is all that’s required to release the door manually. In the event of a fire the Dorgard will release automatically when the fire alarm system activates by retracting the plunger which passes through the main body – the standard model listens for a sound level of over 65 dB while the Pro model is wired directly into the building’s alarm system.The Dorgard is a safe and legal solution that allows you to hold your fire doors open for improved ventilation, wheelchair access, and general convenience. In the event of a fire, the device will automatically release to close fire doors, responding to the sound of a fire alarm. This fire door retainer by Fireco uses an easy foot-operated setting and release system, which unlike magnetic fire door retainers, can hold the door open in any selected position.
