Description

The VAR1 is a relay device that monitors audio activity over a wide range of input voltages and operates two sets of C-Form relay contacts in response to detected activity. The VAR1 can be used to detect voltages as low as signals directly from a microphone or as high as signals from 70V speaker systems. A low-level output of the detected audio, transformer-isolated from the input, is also made available for use with other equipment. The VAR1 can also be used as a balanced, low-impedance microphone pre-amp. The VAR1 is ideally suited to provide a set of contact closures for paging ports of lower cost telephone systems that do not have a set of AUX contacts to trigger paging equipment. An adjustable release delay (up to 25 seconds) keeps the paging system from dropping out in the middle of a page.

Features

  • Monitors audio activity over a wide range of input voltages
  • Two sets of C-Form (both N.O. and N. C.) relay contacts respond to audio activity
  • Four levels of signals: microphone, 600-ohm line, 25V, and 70V speaker systems
  • Built-in balanced, low noise, high gain microphone pre-amp
  • Transformer-isolated, 600-ohm small signal level output of detected audio available
  • Works with self-amplified or central-amplified paging systems
  • Separate microphone pre-amp gain control
  • Adjustable release delay: 0.25s to 25s
  • Trigger threshold adjustment
  • Relay active indicator light
  • Accessories: PRS40C 12V DC Power Supply (sold separately)
