The Dorgard is a legal fire door holder which utilises accoustic sensing technology to detect sounding fire alarms exceeding 65dB.

When the plunger is depressed the rubber foot of the Dorgard comes into contact with the floor which prevents the fire door from closing.

Once the sound level is detected it is verified over a 14 second period, after verification the Dorgard fire door holder will automatically release the rubber foot (within approximately 20 seconds) allowing the fire door to close under the pressure of the door closer.
