The BG-VAR1 Voice-Activated Relay is designed for business and IT environments requiring automated control based on audio input. This device monitors audio activity across various input voltages, including microphone, 600-ohm line, 25V, and 70V speaker systems. It provides two sets of C-form relay contacts (both Normally Open and Normally Closed) that activate in response to detected audio. The unit features a built-in balanced, low-noise, high-gain microphone pre-amplifier and offers a transformer-isolated, 600-ohm small signal level output of the detected audio. It supports integration with both self-amplified and central-amplified paging systems. Adjustable parameters include a separate microphone pre-amp gain control, a release delay from 0.25s to 25s, and a trigger threshold. A relay active indicator light provides operational status. This relay is suitable for applications where audio detection needs to trigger other systems or functions, such as in paging or security setups. It requires the PRS40C 12V DC Power Supply, which is sold separately.
The BG-VAR1 Voice-Activated Relay requires the PRS40C 12V DC Power Supply. This power supply is sold separately and is not included with the relay unit.
The BG-VAR1 can monitor audio activity from multiple signal levels, including microphone, 600-ohm line, 25V speaker systems, and 70V speaker systems.
The relay provides two sets of C-form relay contacts, which include both Normally Open (N.O) and Normally Closed (N.C) options. It also offers a transformer-isolated, 600-ohm small signal level output of the detected audio.
Yes, the BG-VAR1 features an adjustable release delay, which can be set from 0.25 seconds up to 25 seconds. There is also a trigger threshold adjustment.
