UNION, part of ASSA ABLOY Security Solutions, a UK division of ASSA ABLOY, the physical security product company, has introduced DoorSense. The manufacturer describes it as a legal way for fire doors to be kept open for access and able to close automatically in the event of an alarm.
DoorSense is CE marked to EN 1155 standards, meeting legal requirements to allow fire doors to be kept open, assisting access and providing greater movement in a building when needed, while reacting fast should a fire occur.
A battery-operated, stand-alone system, it’s activated by opening a fire door pushing the system’s foot plunger down into the floor plate, holding the door open to ease access into the building. When a fire alarm sounds, DoorSense uses acoustics to identify the alarm and automatically release the foot plunger, allowing the fire door to close via a separate door closer.
No wiring is required. According to the makers, the product can be retrofitted to doors using older holding mechanisms. It will work at any angle, and can be released manually or automatically via the alarm or by using a built-in night closing timer.
Alison Aston, Product Manager for Door Closers at ASSA ABLOY Security Solutions, said: “We designed DoorSense to be really versatile so it can be used anywhere, such as care homes, schools and public facilities. The acoustic technology within DoorSense has also been tested over 50,000 cycles to make sure we can guarantee it will work – that’s in addition to EN1155 and way beyond any tests other similar door release mechanisms are subjected to.
“Our reputation is built on products made to the highest standards that are easy to install. All our products undergo rigorous testing to ensure they perform as expected, and DoorSense is no exception.”
The product can be specified in three colours – black, white or red – and is powered by two Alkaline C batteries, which are included. Visit www.uniononline.co.uk/doorsense.
