As we would recommend with any fire safety device, the Dorgard should have a Fire Risk Assessment carried out on it before installation.

As soon as the Dorgard has been installed, it works by listening out for a repeated fire alarm sound 65 decibels or greater. As soon as the Dorgard notices this sound, after around 14 seconds, it will release the fire door, and the door will shut from the pressure of the overhead door closer in order to seal the area to prevent smoke and fire spreading. As a safety feature, the Dorgard will release at a general noise level of 80 decibels. This is because if the noise level in your building exceeds 80 decibels, you are unlikely to be able to hear a 65 deciblel alarm, so the Dorgard releases the fire door to close.

Being wireless, the Dorgard does not need any wiring into the main fire alarm system of the building, allowing there to be minimum disruption and quick and easy installation.

What differs a Dorgard from electro-magnetic retainers is that it is all battery operated and self-contained, requiring no wiring. It takes around 5 minutes to set-up, and is affixed to the fair door via four screws. Insert the two C-size batteries supplied, and the Dorgard is ready to go.
