TecPro BP511 Single Circuit Beltpack

Single Circuit Beltpack

  • Male and female XLR 3 pin connectors on base for connection to a single intercom circuit
  • Compatible with standard mic cables
  • Loop through for daisy-chaining beltpacks
  • Lightweight, robust high impact ABS case
  • Recessed controls and connectors prevent damage


The BP511 single circuit beltpack has ‘Mic Select’ switches linked in parallel. Pressing either switch will open or close the microphone circuit. The ‘Mic Select’ switches glow green when activated. A single volume control is provided for monitoring via a pluggable headset.

To catch the attention of operators who have removed their beltpack and headset, a call alert signal is sent by pressing the red ‘Call’ button. This produces a combination of 20kHz tone and a DC signal to trigger the call lights on all user stations and outstations on a chosen circuit. DC call signalling has been retained for compatibility with previous Tecpro designs.

When a call alert signal is received on the intercom circuit, the ‘Mic select’ and ‘Call’ buttons flash brightly to attract attention.

For increased visibility, Series 2 beltpacks have a mimic LED on their base so the call alert may be seen from most angles.

A ‘Call’ send/receive confidence tone is also heard in the headset. This may be muted by pressing a combination of buttons on the beltpack.

An optional vibration motor (as used in mobile phones) is available. This triggers when a call alert signal is received. This function can be switched off by pressing a combination of buttons on the beltpack.
