Addressable Sounders / Beacons

Addressable Sounders and Beacons are intelligent alarm notification devices designed to deliver loud, reliable sound output and high visibility flashing signals during emergency conditions. Each unit contains a unique digital address, enabling the fire alarm control panel to identify the exact device location and monitor its status in real time.

These devices are typically used to warn occupants through a combination of audible tones (sounders) and visual flashes(beacons), ensuring effective communication in noisy areas, large open spaces, and environments where hearing-impaired individuals may be present.

With features such as synchronised flashing, programmable tones, adjustable volume settings, and low-current operation, these units offer superior flexibility for a wide range of building types. Their advanced monitoring capabilities allow the system to detect faults, wiring issues, or device failures quickly, improving overall system reliability.

Designed for commercial, industrial, and residential applications, these devices are easy to install and compatible with Inbuild UK's addressable fire alarm systems. Their robust construction ensures long-term durability, even in demanding environments.

They are alarm notification devices that provide audible (sounder) and visual (beacon) alerts during fire emergencies, with each unit having its own address on the system.

Conventional devices trigger general zone alarms, while addressable devices allow the control panel to identify exact device locations, improving fault finding and system control.

Yes. Many models support programmable tones, synchronised flashing, and adjustable volume levels to suit the needs of different environments.

They are used in offices, schools, warehouses, industrial plants, apartment buildings, and any setting requiring clear emergency alerts.

Yes. Because each device reports its status, including faults or wiring issues, engineers can diagnose problems faster and more accurately.

They must be used with a compatible addressable fire alarm control panel. Always check system requirements before installation.

Most PIV units operate as stand-alone devices. Where monitoring is required, relays or add-on modules can provide run/fault signals for integration into a BMS. Documentation should show how signals are connected and tested.

Typical constraints include limited loft or ceiling void space, structural fixing points, duct routing, and safe access for servicing. Poor mounting can result in vibration or noise being transmitted into living spaces.

If noise is a problem, installers should check fan speed settings, ductwork routing, and ensure seals and fixings are secure. Additional silencers, acoustic insulation, or repositioning the fan or outlet may help reduce noise.

PIV fans must have enough capacity to maintain airflow as filters become dirty. Units should include filter change indicators where possible, and maintenance schedules should specify inspection and replacement intervals to prevent performance loss or motor strain.
