BELL - 40 Call Button Flush Audio Entry Aluminium Panel

Bell SPA40 is a flush-mounted audio panel with 40 call buttons, made from durable anodised aluminium. Cost-effective and reliable, it provides secure communication for large multi-occupancy buildings.

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