Improves access for wheelchair users in line with the Disability Discrimination Act (DDA). 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 Holder 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 operates alongside any existing fire alarm system currently in place. This is also the required alarm sound level for populated areas according to BS 5839-1. Dorgard Floorplate: The Dorgard floorplate is designed for use with an installed Dorgard and is fitted to the floor using 4 screws. Fire doors weighing more than 120Kg, which have a closing force in excess of 120nm (that is a force of about 15kg, 800mm from the hinge) must have the floorplate installed in combination with the Dorgard unit. Dorgard can hold a fire door open safely without the floor plate installation if the fire doors weight and closing force are less than that above. Installing a Dorgard floorplate is recommended when. Your fire door has a powerful overhead door closer and the fire door tends to creep closed even with a Dorgard fitted. The floor is slippery or has a very smooth surface and the fire door tends to creep closed even with a Dorgard fitted. 2 x 1.5V C-Size Alkaline Batteries.
