DoorSense

DoorSense holds your fire doors open, improving access around your building. If the fire alarm sounds, DoorSense automatically releases to let the door close.* It is quick and easy to install with no secondary installation costs, such as electrical wiring, and retrofits existing products. CE marked to EN 1155, EMC tested, and fire rated for timber doors (FD120), legally allows fire doors to be held open for easier access and sound tested over 50,000 times, so you can depend on it working. *A separate door closer must be installed. It is recommended DoorSense is used in conjunction with a professionally installed fire alarm system.
