mode which allows the relay to follow ringing or to remain activated during the off time of stan-

dard ring cadence.

The LDB-3 comes complete with a 12 VDC power adapter, and can also provide switched

12VDC .35 Amp output to power

external lights, etc. during ringing

and/or off-hook conditions.

LDB-3

Advanced Ring/

Loop Detector

February 21, 2008

Ideal for Use with Two-Button Emergency Phones!

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 acti-

vated 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

Provide a Contact Closure

During Ringing and/or Off-Hook

• 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 or (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
