  • Viking Advanced Loop Detector loop detect board for ring and line "in use" contact closures
  • Provide a contact closure during ringing and/or off-hook
  • Monitors an analog phone line for ringing or an off hook condition
  • A built-in relay can be activated when either of these conditions are detected
  • This is ideal for monitoring line status or for providing a visual indication of such
  • Disable input is ideal for two-button emergency phones, such as Viking's E-1600-20A, allowing "Info" button calls to be placed without activating the relay (turning on the emergency strobe light, camera, etc.)
  • 3 DIP switches are provided for turning ring detection on or off, off-hook loop detection on or off and for selecting a ring cadence mode which allows the relay to follow ringing or to remain activated during the off time of standard ring cadence
  • Complete with a 12 VDC power adapter
  • Can also provide switched 12VDC .35 Amp output to power external lights, etc. during ringing and/or off-hook conditions
  • Applications: control a strobe or beacon light for ring indication, provide relay closures on off-hook, trigger a security camera, trigger a tape recorder, phone "in use" indicator
  • Detects ring voltage and off hook loop current
  • On/off switches for ring detection and off hook/loop detection
  • Screw terminal connections
  • Selectable ring cadence mode (relay can remain on between rings)
  • Wall mountable with foam tape (included) or screws (not included)
  • Switched 12V DC output (follows relay activation for powering strobe lights, cameras, etc.)
  • One set of (NO) normally open and (NC) normally closed relay contacts provided
  • Disable input, ideal for use with two-button emergency phones (E-1600-20A), will not activate relay on "Info" calls
  • Made in the USA
  • 1 Year manufacturer's warranty
  • Power: 120V AC to 12V DC adapter provided
