Viking LDB-3 Loop and Ring Detector Board

Key Features:

• Mfr. Part #: LDB-3
• 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
• Power: 120V AC to 12V DC adapter provided
