Aperçu
The LDB-3 Advanced Loop Detector monitors an analog phone line for ringing and/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.
The LDB-3's 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.)
Three 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.
The LDB-3 comes complete with a 12 VDC power adapter, and can also provide switched 12VDC 0.35 Amp output to power external lights, etc. during ringing and/or off-hook conditions.
