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. The BP531 is as the BP511 but includes vibration alert.
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.
