Wire Free Door Holders
Wire free fire door holders offer a convenient and compliant way to legally hold open internal fire doors without the need for hardwired connections. These devices are ideal for buildings where accessibility, ease of movement, and cost-effective installation are key considerations—such as care homes, schools, offices, and hospitality settings. At Firesense, we stock a carefully selected range of wireless fire door holders, including advanced solutions from Agrippa, Apollo, and Salamander, designed to integrate with fire alarm systems and support full compliance with UK fire safety regulations.
Fire door retainers help ensure buildings remain accessible by holding doors open under normal conditions. In the event of a fire, they release automatically to allow the door closer to shut the door, helping to prevent the spread of smoke and flames. Wire free models deliver the same functionality as hardwired units but with faster installation, reduced disruption, and no need for cabling infrastructure.
Agrippa Magnetic Fire Door Holder
The Agrippa wire free door holder is a battery-powered, wall-mounted device that uses a magnetic plate to hold internal fire doors open. It is easy to install—with no wiring required—and features a slimline design suitable for use in corridors and shared spaces. A matching keeper plate is fitted to the top of the door to avoid floor damage or warping, and there is also the option for floor-mounted installation where needed. One of the Agrippa’s standout features is its 'listen and learn' technology, which allows the device to recognise the specific sound pattern of a building’s fire alarm. This ensures it only activates when the actual alarm is triggered, rather than reacting to everyday background noise like doors slamming, vacuum cleaners, or children. The device can be installed in under 10 minutes and includes a manual release button, low battery warning, and a daily timed release option to automatically close doors at set times—for example, overnight.
Recognised by the UK Fire and Rescue Services and conforming to EN1155 and BS 7273-4 (Category B), the Agrippa fire door holder is CE marked and suitable for a wide range of applications, especially where minimal disruption and fast installation are priorities.
Apollo ADR XP95 Door Retainer
The Apollo ADR is an addressable device designed for use directly on an XP95 loop, making it an excellent choice for systems using Apollo protocol. It provides fire door holding functionality without separate wiring, allowing for controlled release based on the fire system’s programming. The ADR is suited for all fire door types, including critical actuation doors, and can be installed as part of a fully addressable fire alarm network, offering integration and monitoring through the fire panel.
Salamander Wireless Door Retainers
Where environments are particularly noisy or the sound-activated method of release may be prone to false triggers, the Salamander radio-controlled door holder offers an alternative wire free solution. This device uses radio signals rather than acoustic activation to trigger the release mechanism. It is ideal for busy environments such as schools, workshops, or kitchens where sound levels vary widely. The Salamander system offers reliable performance in challenging acoustic conditions and can be integrated with fire alarm systems via a radio interface controller.
