Inline Box Fan

Inline Box Fans must be selected to meet duty points while ensuring compliance with site airflow and noise criteria. Contractors should allow for appropriate mounting and vibration isolation during installation to reduce rework. Where fans are used for smoke extract, compliance with EN 12101-3 must be ensured. Commissioning involves verifying rotation, flow rates, and BMS signals in accordance with the design intent. Maintenance access, safe isolation, and clear O&M records are key to long-term performance. Engineers often reference guidance such as Approved Document F for ventilation requirements, and relevant fan performance or smoke extract standards depending on the application. Practical checks on O&M documentation and duty point verification help improve reliability and site efficiency.

General Information

Learn more about Addressable Sounders and Beacon

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 flashingprogrammable tonesadjustable 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 commercialindustrial, 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.
