C-TEC Addressable Sounder Base for Fire Alarm Detectors

In conventional and addressable fire alarm system design, it is common to co-locate detection and audible output in the same area. A sounder base achieves this efficiently by combining both functions into the detector mounting base itself, so the detector and sounder occupy a single ceiling position rather than requiring two separate devices.

The C-TEC BF431A is an addressable sounder base compatible with the relevant range of addressable detectors, providing the mounting, circuit connection, and sound output for the fitted detector. When the system activates, the sounder base produces audible output from the detector’s own ceiling position, contributing to the overall sound coverage of the building alongside any standalone sounders in the system design.

This approach reduces the device count and the number of ceiling positions needed, which is valuable in spaces with limited ceiling penetration options, in listed buildings, or where the overall number of visible devices needs to be kept to a minimum.

For fire alarm engineers designing and installing addressable systems across commercial and public sector buildings in London and the UK, specifying a sounder base where detection is planned is an efficient way to achieve simultaneous detection and sound coverage from a single installation point.
