Safelincs are pleased to launch Geofire’s Agrippa acoustic fire door holders and free-swing fire door closers, featuring industry leading technology that enables the devices to recognise the specific sound of your fire alarm.
Both devices are designed to improve free movement within a building by keeping fire doors open while closing the doors in the event of a fire to stop the spread of fire and smoke through the building. Here a short description of their principal function:
Fire Door Holders (also called fire door retainers) are installed on fire doors that have already an overhead fire door closer installed. They hold the fire door open against the pressure of the closer and will release the fire door in case of a fire, allowing it to be closed.
Free-Swing Fire Door Closers are installed instead of normal overhead fire door closers. They exert no closing pressure on the door in normal operation, therefore allowing the fire door to swing freely, just like a normal door. In the event of a fire their function changes to that of a normal door closer
, forcing the fire door shut.
Most traditional fire door holders and free-swing door closers are connected to the fire alarm system by wire and receive their signal to close from the fire alarm panel. The Agrippa acoustic technology, however, is triggered by the acoustic sound of your smoke alarm or fire alarm system sirens. This is particularly helpful for premises without a fire alarm system and central panel, or where retrofitting a wired system would be problematic.
Unlike other acoustic fire door holders and fire door closers, Geofire’s Agrippa devices listen to and then learn and recognise the sound of your particular fire alarm siren or smoke alarm, meaning that they won’t trigger your fire door to close if they hear other loud noises. This ground-breaking technology will therefore reduce the number of false door releases.
Both the Agrippa fire door holders and the Agrippa free-swing door closers are wireless and very easy to install on existing or new fire doors. They are fitted to the top of the door in a discreet way and allow you to keep fire doors open legally and effectively giving you the flexibility you need to allow free movement within the building. They enhance the accessibility for the disabled and improve ventilation.
The Agrippa acoustic door holder retains fire doors in the fully open position. No intermediate positions of the fire door are tolerated. The main Agrippa body, containing the sensors and a strong electromagnet, is fitted on the wall behind the door and a steel plate is fitted to the back of the door which the magnet then holds. On hearing your fire alarm the magnet is switched off and the fire door will be closed shut by the closer fitted to your fire door.
In comparison, the Agrippa free-swing door closer allows you to use your fire door like a normal door, meaning that it swings freely and can be left open in any position. When the device hears your fire alarm the integrated door closer will be triggered and closes the door, stopping the spread of fire and smoke.
Keeping fire doors shut or having a system in place that closes fire doors in case of a fire is a legal requirement . A breach of this requirement can lead to prosecution and even prison sentences.
