Agrippa door holders are a brilliant wire-free solution to legally holding a fire door open. This is important for ease of access, free movement around a building and increasing air flow on hot days.
The devices listen and learn the sound of your specific fire alarm, releasing the door in the event of a fire. The releasing trigger reacts to a particular sound rather than simply a loud noise, significantly reducing false activation. This new innovation in the industry is wire free, so it can easily be retrofitted to any door. No bulky units, no awkward cabling runs, no interfaces required just a simple 10 minute installation. Agrippa acoustic products are a cost effective plug and play type solution..
With a range of colours available the Agrippa blends into any property, being small and compact compared to other Door Holder units.
