BELL - 42 Call Button Flush Audio Entry Aluminium Panel

Bell SPA42 is a flush-mounted audio panel with 42 call buttons, made from durable anodised aluminium. Part of the SPA series, it provides reliable communication for a large multi-dwelling buildings.

Installers recess the modular panel into the building masonry using the provided flush-mounting back boxes to ensure a neat, low-profile finish that is resistant to tampering. The system utilises a traditional 4+n wiring architecture to connect the forty-two call buttons and the speech module to internal audio handsets via centralised power supplies and controllers. During daily operation, visitors locate the correct resident using the integrated nameplate slots and press the assigned button to initiate two-way voice communication. This installation is ideally suited for high-density apartment blocks, sheltered housing schemes, and large commercial office complexes where a durable, high-density analogue audio solution is required.
