Dorgard with free 5 Year Warranty exclusively from Safelincs
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.
Improves access for wheelchair users in line with 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 signals the plunger to retract, allowing the fire door close normally (Dorgard will release after approximately 14 seconds). Dorgard is battery operated, so there is no need for complex and expensive wiring. Please note that your alarm's sound level has to be higher than 65dB at the location of the door to allow the Dorgard to pick up the alarm up. This is also the required alarm sound level for populated areas according to BS5839-1:2002 (Clause 16.2).
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.
Q. Will the Dorgard release automatically at night?
Yes, if set to do so. There are three timed setting options for night time release which the installer can select prior to installation. Batteries to activate the internal clock in the Dorgard must be inserted at 12.00hrs (midday) and the night time settings can then be selected and set accordingly. The Dorgard will then release each night at the pre-determined time.
Q. Where Dorgards have been fitted should employees be made aware of them?
Employees should be informed about Dorgard and instructed on its use and operation and include it in the workplace fire routine.
Q. Does a fire alarm audibility test need to be carried out before fitting Dorgard?
As Dorgard is an audio sensing device that can be adjusted within certain limits, it is not necessary to carry out a test before the installation. If the Dorgard cannot detect the alarm to respond to it the likelihood is that the alarm is not sounding at the minimum level required by BS 5839 which should alert the user to a problem with the alarm system that will require remedial action.
Q. Can the Dorgard test itself?
A self-test routine is run every seven days by the Dorgard. The plunger is released, closing the door and the unit will emit a warning alarm if a fault is detected.
Q. Will the closing of a fire door by a Dorgard affect other units by restricting the sound of the fire alarm through the closed door?
No, the operation of the Dorgard, or the ability to hear the fire alarm, should not be affected provided the sound level stated in BS5839 is adhered to throughout the building. Dorgards can be adjusted if the sound level does drop slightly within performance limits.
