DoorSense Acoustic Door Holder
DoorSense is a standalone unit which can be fixed to a fire door in seconds to provide a reliable way to keep it open but will automatically release if the fire alarm sounds.
Incredibly easy to install, the DoorSense needs no wiring or special skills - it can even use the same footprint as some older units.
Once fitted, DoorSence is powered by 2 alkaline C batteries for long working life and has a low battery indicator to help you keep the unit in excellent working order.
