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. DoorSense is incredibly easy to install, needing no wiring or special skills - it can even use the same footprint as some older units. Once fitted, DoorSense is powered by two Alkaline C batteries for long working life, and has a Low Battery indicator to help you keep the unit in excellent working order.

Preventing a fire door from closing can put your insurance at risk - and land you in court if a fire takes hold. But you still need a way to hold a fire door open for ease of access. DoorSense is the new way for you to keep a fire door open - and have it close if the alarm sounds, or at a set time.

DoorSense is designed to be robust and practical. A curved, fire-retardent casing helps to deflect impacts and stay looking smart even when subjected to extreme treatment, while the unit footprint allows it to be a direct retro fit for older fire door hold open devices.

Once in place you can have it working manually or automatically via a timer to set a night release time, and then leave DoorSense to get on with the job of giving easy access while keep your staff safe.

DoorSense is available in three colours: Black, Red and White, and comes supplied with full fitting and setup instructions along with batteries for instant startup.

Suitable for use with fire rated doors using door closers with power rating between 3-7
