Completely wireless and battery operated the Dorgard fire door holder keeps fire doors open safely and legally. Dorgards are inconspicuous units that are ideal for installation in both public and private premises including public sector buildings, office blocks, nursing homes, schools, educational sites, hospitals and care trusts to name but a few. The design both improves users access through a building when the fire door is being retained helping conformity to the Equality Act 2010. The Dorgard door holder releases the fire doors in an emergency when the fire alarm sounds by detecting the acoustic signal from the alarms.

The following datasheets are available for this product.
Q. Will the Dorgard release automatically at night?
A. 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?
A. 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?
A. 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. 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?
A. 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.Show all FAQs
