Loop and Ring Detector Board

The Loop and Ring Detector Board is an advanced loop detect board designed to provide a contact closure during ringing and/or off-hook. It monitors an analog phone line for ringing or an off hook condition and activates a built-in relay when either of these conditions are detected. This is ideal for monitoring line status or for providing a visual indication of such. The disable input is ideal for two-button emergency phones, allowing "Info" button calls to be placed without activating the relay. The board features on/off switches for ring detection and off hook/loop detection, screw terminal connections, selectable ring cadence mode, and a switched 12V DC output for powering external lights, cameras, etc. One set of (NO) normally open and (NC) normally closed relay contacts are provided. Made in the USA with a 1-year manufacturer's .

• 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)
• 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
• Wall mountable with foam tape (included) or screws (not included)
• Power: 120V AC to 12V DC adapter provided

• Provides a contact closure during ringing and/or off-hook
• Built-in relay can be activated when either of these conditions are detected
• Disable input is ideal for two-button emergency phones
• 3 DIP switches for turning ring detection on or off, off-hook loop detection on or off, and for selecting a ring cadence mode
• 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
