Viking Electronics VK-LDB-3 Loop and Ring Detector Board

- 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 Vikings 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 manufacturers warranty-
Power: 120V AC to 12V DC adapter provided- VKLDB3
