LDB-2
Ring/Loop
Detector
December 15, 2011
The LDB-2 Ring/Loop Detector monitors an analog phone line
for ringing or an in-use condition. A built-in relay can be activat-
ed when either of these conditions are detected. This is ideal for
monitoring line status or for providing a visual indication of such.
When monitoring for ring, an internal pot can be adjusted to
allow the relay closure to stay on steady, or follow standard ring
cadence.
The LDB-2 comes complete with a 12 VDC power adapter, and
can also provide 12V DC power through its auxiliary 12V DC
output terminals.
