Bogen VAR1 Voice Activated Relay for 70V Paging Systems

Keep paging, monitoring, and security announcements reliable with the Bogen VAR1 voice-activated relay. Designed for AV and security professionals, this voice-activated relay senses audio activity from low-level microphone signals up through 70V speaker lines, converting audio presence into two sets of C-form (DPDT) contact closures for paging ports, access control, or alarm integrations. The VAR1 includes a low-noise balanced microphone pre-amp and a transformer-isolated low-level output for seamless connection to mixers, amplifiers, or surveillance recorders. An adjustable release delay (up to 25 seconds) prevents pages from dropping out mid-announcement, while the LED activity indicator speeds diagnostics during installation. Ideal for lower-cost telephone systems without auxiliary paging contacts, the VAR1 simplifies deployment of paging and security communications across schools, retail, healthcare, and enterprise facilities. Backed by Bogen quality and a 2-year limited warranty, this relay reduces false triggers and improves the reliability of your surveillance and monitoring workflows. Add the VAR1 to your paging or security integration to streamline control and ensure consistent announcements—contact your distributor or order today.
