Voice Activated Relay

Product description

• Versatile audio detection: The DPDT relay activates upon detecting audio activity from multiple input sources, including microphone, 600-ohm line, 25V, and 70V inputs, making it ideal for priority paging and emergency announcements
• Precision control: Features adjustable VOX sensitivity (20 mV to 150 mVrms) to set the exact trigger threshold and an adjustable release delay (0.25 to 25 seconds) to prevent audio dropouts during pauses in paging
• Audio interface: Includes a built-in balanced, low-noise, high-gain microphone pre-amp with separate gain control, plus a transformer-isolated 600-ohm audio output for integrating additional equipment
• System compatibility: Designed to work seamlessly with both self-amplified and central-amplified paging systems, featuring an input source selector switch for Mic or Line level signals and a visual LED status indicator
• Robust switching capability: Provides two sets of C-form relay contacts offering both Normally Open (N.O.) and Normally Closed (N.C.) operation, rated at 2A at 30V DC or 0.5A at 120V AC. (Requires external 12-24V DC power supply, sold separately)
