Expert Overview

The Teledynamics BG-VAR1 Voice Activated Relay is designed for integrating audio detection into various control systems. This unit monitors audio activity across a broad spectrum of input voltages, including microphone, 600-ohm line, 25V, and 70V speaker systems. It features two sets of C-form relay contacts (both normally open and normally closed) that activate in response to detected audio. The system includes a balanced, low-noise, high-gain microphone pre-amplifier with independent gain control, and offers a transformer-isolated, 600-ohm small signal level output of the detected audio. With an adjustable release delay from 0.25 to 25 seconds and a trigger threshold adjustment, this relay is suitable for use with both self-amplified and central-amplified paging systems, enabling automated responses based on audio presence.
