Legal Conformance and Safety

DoorSense is Compliant with BS EN 1155 – EMC Tested and rated for timber doors (FD120) and offers a legally compliant way of leaving a fire door open for deliveries, improved ventilation or any other reason.

The unit is designed to automatically release the door when the fire alarm sounds. It features an easy sensitivity adjustment to ensure optimum performance in any specific locations where the standard sensitivity setting may result in the release mechanism being activated by general high noise volume other than a fire alarm, for instance.

When used, the timer function can be set to automatically release the door at a given time, i.e. you may decide that doors should automatically close at 6 pm (or any other time you choose). Of course, there is also a manual override, so a gentle tap on the kick stop will immediately release the retainer foot from the floorplate, allowing the door to close.

Additional Products for use with DoorSense

Door Closer – once the fire door is released, a door closer mechanism is obviously needed to actually close the door. The Union RetroV overhead door closer is an ideal choice, delivering reliable performance at a very modest price. (it`s also a straight forward and cheaper replacement for other manufacturers older door closer units, often even using the same fixing holes).

 

Preventing Finger Trapping Accidents – closing fire doors can pose a risk of injury to fingers especially among children or the elderly. A finger trapped in the hinge cavity of a closing door, for instance, could result in painful injuries and ultimately even amputation.

According to ROSPA (Royal Society for the Prevention of Accidents) and as reported by BBC News (October 2017), About 30,000 children trap their fingers indoors each year and more than 1,500 of them need surgery according to Bapras (British Association of Plastic, Reconstructive, and Aesthetic Surgeons), self-shutting fire safety doors, car doors, and hinges are the top three causes of finger and hand injuries in children.
