Union Wireless Fire Door Holder Red
The Union DoorSense J-8755A Acoustic Release Hold-Open Unit is a compliant fire door holder that integrates seamlessly with your existing fire alarm system. It enhances accessibility while ensuring that fire safety measures remain intact. Commonly used in schools, care homes, hospitals, and other public buildings, the DoorSense unit allows for ventilation, wheelchair access, and increased convenience. Unlike a standard door wedge, this device automatically closes an open fire door if a potential fire is detected.

This standalone unit is easy to install on a fire door, providing a reliable method to keep it open. It will automatically release the door if the fire alarm sounds at over 80dB for more than 15 seconds. The unit requires no wiring or special installation skills and can often be installed using the same footprint as older units. Powered by two Alkaline C batteries, it offers a long operational life and features a low battery indicator to ensure continuous reliability.
Once installed, the DoorSense can operate manually or be set on a timer for automatic night release, giving you peace of mind while maintaining easy access throughout the day. The unit's robust design, with its curved and red fire-retardant casing, deflects impacts and maintains a smart appearance even under heavy use.
