Provide a Contact Closure on Ringing
or Off-Hook
The LDB-2 Ring/Loop Detector monitors an analog phone line
for ringing or an in-use 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.
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.

IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from both the AC outlet and
the telephone line. It is recommended that a surge protector be installed to protect against such surges. Contact Panamax
at (800) 472-5555 or Electronic Specialists Inc. at (800) 225-4876.
C. Ring Detection Only
Connect the incoming line to terminal block positions 1 and 2, as shown in the diagram to the right. No terminal device
is required. In this manner, the LDB-2 can monitor for ringing any place along the ringing line.
D. Ring and Loop Detection
If the application requires loop as well as ring detection, the LDB-2 must be placed between the phone line and the
terminal device to be monitored. Connect the incoming line to terminal block positions 1 and 2 and connect the terminal device to positions 3 and 4, as shown in the diagram above.
E. Relay Contacts
Relay contacts are available at terminal block positions 5,6 and 7,8. If the contacts are driving an inductive load, be
sure to place a suppression device at the load to snub any high voltage spikes.
F. Auxiliary 12V DC Output
12V DC is available for low current applications. The positive side is available at terminal position 10, and the negative
side is at position 9. Once all the line and load connections have been made, plug in the 120 V AC wall adapter, and
replace the cover.

A. Adjustable Relay Closure Time Out
The time out POT (see diagram above) can be adjusted from 2 to 6 seconds. Turn the time out POT counter clockwise to decrease the closure time. Turn it clockwise to increase the closure time. When monitoring for ring, turning the
time out POT fully counter clockwise will allow the relay closure to follow standard ring cadence, turning it fully clockwise will allow the relay closure to be maintained during the entire off time of the ring signal. When monitoring for loop,
the relay closure will be maintained while off-hook and will time out following an on-hook.
B. Relay Contact Selections
The relay contacts located at terminal positions 5,6 and 7,8 can be set for normally open (N/O

C. Disabling Ring Detection
If no ring detection is required (loop detection only), clip R2 as show in the diagram on page 3. R2 is a 4.7K ohm resistor that is mounted vertical on the board. (For use with 0.0 REN loading only.)
Operation
A. Ring Detection Only
With the LDB-2 in the ring detection mode, incoming ring will activate two relay contacts. The contacts can be independently configured to be either normally open or normally closed. Once ringing is detected it will remain activated
for an adjustable time of 2-6 seconds. During the activation time, if ringing stops, the relay will remain activated for the
balance of the set time.
B. Ring and Loop Detection
With the LDB-2 in the ring and loop detection mode, incoming ring will activate two relay contacts. The contacts can
be independently configured to be either normally open or normally closed. Once ringing is detected it will remain activated for an adjustable time of 2-6 seconds. During the activation time, if ringing stops, the relay will remain activated
for the balance of the set time. Additionally, the LDB-2 will detect an off-hook condition. If the device goes off-hook at
any time, either with or without ringing, the relay will activate and remain activated for the duration of the off-hook condition.
