The Dorgard is a safe and legal solution that allows you to hold your fire doors open safely, while automatically closing them in the event of a fire. This allows for better wheelchair access, ventilation and all-round convenience without jeopardising safety or breaking the law. Dorgard has a rubber plunger/stopper which remains in contact with the floor and, unlike magnetic fire door retainers, can hold the door open in any selected position. When a fire alarm sounds, the integral audio-electronic device inside the Dorgard signals the plunger to retract, allowing the fire door close normally (Dorgard will release after approximately 14 seconds). Dorgard is battery powered, so there is no need for complex and expensive wiring into the building's fire alarm system. This means that the Dorgard can be installed and operated alongside any existing fire alarm system currently in place. Please note that your alarm's sound level has to be higher than 65dB at the location of the door to ensure that the Dorgard is able to pick the alarm up. This is also the required alarm sound level for populated areas according to BS 5839-1.
