dorgard

Self closing fire doors are usually a vital part of the fire defence of a building, they are designed to prevent  not only the spread of fire, but also the toxic gases that can incapacitate and kill in seconds. The down side is that they often restrict free movement especially in premises such as residential care and nursing homes. Unfortunately many people do not understand the importance of fire doors, and it is not unusual to find fire doors held open with anything from wedges to fire extinguishers, a practice that is both dangerous and illegal.

There is an answer to the problem, door detents, or in simple terms 'hold open devices', which can be fitted to a door to hold it open, but release if the fire alarm actuates. These come in all shapes and sizes, some actually hold the door open whilst others allow the door to swing freely and only close when activated. The problem with these is usually the cost, or in many cases a lack of knowledge that such devices exist. They must also work in tandem with the fire alarm, which itself must incorporate automatic fire detection in order to work independently and automatically in case of fire. If hold open devices are not installed during the construction stage, or during refurbishment, they can be expensive as they require to be 'hard wired' to the fire alarm panel.

There is however a cost effective solution to the problem; Dorgard, a battery powered device that can be fitted to a fire door quickly and easily. It is a stand alone unit that releases when the fire alarm sounds (even domestic smoke alarms), allowing the door to close. The unit is powered by 2 x 'C' cell batteries (supplied) and even contains a timer which can be set to automatically release at one of three pre-determined times each night and will not 're-set' until the next morning. Dorgard can also be set to keep the door open continuously.

Once the unit is fixed to the door, a plunger is depressed by foot and the door is held open. Dorgard then 'listens' for the fire alarm and releases when it goes off, allowing the fire door to swing shut.

An LED flashing red light indicates that the unit is operational. In the event of low battery power or battery tampering Dorgard releases allowing the door to close. In addition to this, the unit sounds a repeated warning tone and flashes the LED to indicate a low battery.

Battery life usually exceeds 12 months.

Dorgard can also be released by lightly kicking the plunger (if a floor plate is NOT in use) or by pushing the door in the open direction.
