Alarm Verification Icon

Alarm Verification

Alarm verification combined with local device alarm sounding is an established technique to reduce localised unwanted alarms affecting other occupancies, particularly in HMO’s (house in multiple occupation). Each smoke detector is therefore programmable (at the panel) and, if set to verify mode, will only raise a local alarm during the verify period chosen, prior to a full evacuation taking place. During the verification period, if the smoke or heat level drops below the alarm threshold, the affected local sandwich sounder will auto-reset and the system will return to normal without manual intervention.

Networking Icon


ProFyre Repeater

The A2 panel can be installed with a repeater connected (fully functioning). An A2 system can support up to 4 repeaters.

ProFyre Addressable Devices

Complemented by a complete range of ProFyre addressable field devices, the ProFyre A2 is the perfect choice for systems that require straightforward alarm management and ease of use.

Wi-Fyre Icon

Wi-Fyre Compatible


For complete system flexibly, a loop powered Wi-Fyre Transponder can be connected at any point on the A2 loop wiring, enabling matching 'wireless' detector, call points, sounders or interfaces to be seamlessly connected to the wired system. This means that, wireless devices can now be specified and used on an 'as-needed basis' on a ProFyre addressable system, without the need for additional power supplies and associated wiring.
