    - 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
    - VKLDB3
