COMMUNICATION & SECURITY SOLUTIONS

Provide a Contact Closure

During Ringing and/or Off-Hook

Features

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 activated when ei-

ther 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 ac-

tivating 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 al-

lows the relay to follow ringing or to remain acti-

vated 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 .35

Amp output to power external lights, etc. during

ringing and/or off-hook conditions.
