The Agrippa door closer by Geofire learns the sound of your specific fire alarm, releasing the door in the event of a fire. This new innovation in the industry is also wire free, so it can easily be retrofitted to any door. The releasing trigger reacts to a particular sound rather than simply a loud noise, significantly reducing false activations. It is ideally suited to environments such as care homes, schools and hospitals where it is essential to have doors in an open position at certain times of the day to aid access, but equally as important to ensure the doors are closed in the event of a fire. The Agrippa Fire Door Closer features the `free swing mode` which allows the door to be held open in any position. The special feature of the Agrippa, however, is that it uses Geofire’s `Listen and Learn` technology, meaning this product is able to recognise the sound of your building’s fire alarm. This sound triggers the automatic release of the door, keeping the building safe by preventing the spread of fire. This item is CE marked and EMC approved, as well as conforming to EN1155 and EN1154. The closer is easy to install, only requires C cell batteries (which last for 12 months), can be programmed for daily release and has adjustable closing speeds. Suitable for installation to BS 7273-4 Standard Actuation (Category B). Other features include a seven segment LED display, manual release button and a low battery warning display.

This hold-open magnet from Asec is designed for wall mounting and has a holding force of 45Kg. It has been successfully fire tested to BSEN1634-1 and is suitable for both 30 & 60 minute fire door applications.

The Briton 3934 electromagnetic door closer is a high-performance overhead closer designed to provide controlled door operation while integrating seamlessly with modern fire safety systems. Suitable for use on internal fire doors in high traffic environments such as schools, hospitals, and commercial buildings, it offers both hold open and swing free functionality. The unit operates via a 24V DC connection to a building’s fire alarm or smoke detection system, allowing the door to remain open during normal use and automatically close when the alarm is triggered or power is lost. With adjustable closing speed, latch action, and an EN 3–4 power size, it can accommodate doors up to 1100mm wide and 80kg, ensuring reliable and adaptable performance. The electromagnetic hold open mechanism is controlled by the fire alarm system, releasing the door in the event of activation so that it closes securely to restrict the spread of fire and smoke. This makes it particularly suitable for environments where accessibility is required without compromising compartmentation. Its UKCA and CE marked and fully compliant with EN 1154 (controlled door closing devices) and EN 1155 (electrically powered hold-open devices). It complies with accessibility guidance such as Approved Document M, is Certifire approved (CF5598) and has been fire tested in accordance with EN 1634-1 for use on timber fire doors, achieving up to a 2-hour (120-minute) fire resistance rating, making it suitable to be confidently specified as part of a compliant fire door assembly.

The dormakaba, formerly known as DORMA, TS73EMF combines a hydraulic door closer with an electromagnetic hold-open unit. When used in conjunction with a fire alarm or smoke detection system, it provides a hold-open solution for fire and smoke check doors, with the door held open under electromagnetic control.In the event of a fire, the integral hydraulic closer reliably closes the door. The closing cycle can also be triggered by manual door operation or automatically in the event of a power failure. The TS73EMF is Certifire approved and fire rated for timber fire doors up to FD120 and metal fire doors up to FD240.
