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
