PRODUCT MANUAL

Designed, Manufactured and Supported in the USA

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.

hook/loop detection

Installation

IMPORTANT: Electronic de-

vices are susceptible to lightning

and power station electrical

surges from both the AC outlet

and the telephone line. It is rec-

ommended that a surge protec-

tor be installed to protect against

such surges.

Screws

Step 1. Unsnap the plastic cover and remove the top

screw holding the circuit board.

Step 2.

Loosen the bottom screw and rotate the circuit

board to the left, exposing the two mounting

holes in the base.

Step 3.

Screw the base to the wall, etc. using (2) #6

flathead or sheetrock screws. Note: Make

sure the screw heads are fully driven into the

base to avoid shorting the circuit board leads.

Step 1.

Clean the back of the LDB-3 and the surface

you are mounting to with rubbing alcohol be-

fore mounting.

Step 2.

Remove the backing on one side of the tape

and adhere to the LDB-3. Remove the rest of

the backing and press unit firmly to surface you

are mounting to.

The LDB-3 must be placed between the

phone line and the terminal device (phone)

to be monitored. Connect the incoming line

to positions 1and 2and connect the terminal

device (phone) to positions 3and 4.

If the application requires off-hook (loop) and

ring detection, the LDB-3 must be placed

between the phone line and the terminal de-

vice (phone) to be monitored. Connect the

incoming line to positions 1and 2, connect

the terminal device (phone) to positions 3

and 4.

Connect the incoming line to terminal block

positions 1and 2as shown in the diagram.

No terminal device (phone) is required. In

this manner, the LDB-3 can monitor for ring-

ing any place along the ringing line.

DIP switch 2is used for switching between different ring detection modes. In the OFF position, the relay and

switched 12VDC output will activate only while ring voltage is present and will turn off between rings. In the ON

position, the relay and switched 12VDC output will remain on for up to 5.75 seconds after the ringing has stopped.

This allows the relay and 12VDC to remain on between rings of a standard ring cadence. Note: To use the Ring

Cadence Mode, ring detection MUST be enabled (DIP switch 1- ON).

C. Off-Hook / Loop Current Detection Only

D. Ring and Off Hook / Loop Current

Detection

The switched 12V DC output is a low current, 12-15VDC output that is turned on only while the ring/loop detect

relay is activated. This switched power output is ideal for lighting strobe lights or powering up any device that

draws less than 350mAmps. The positive side is available at terminal position 11, and the negative side is at po-

sition 10. Once all the line and load connections have been made, plug in the 115 V AC wall adapter, and replace

the cover.

Normally open and normally closed relay contacts are available at terminal block positions 7, 8, 9. The contacts

are rated at .5A @ 125VAC/1A @ 30VDC. If contacts are driving an inductive load, place a suppression device

at the load to snub high voltage spikes.

F. Relay Contacts

G. Switched 12V DC Output

By connecting the Disable/Info Switch input of the LDB-

3to the “Info” switch of Viking’s E-1600-20A, E-1600-

20A-EWP, E-1600-52A or E-1600-52A-EWP Emergency

Phone (not included), any outbound calls initiated from

the “Info” button will not activate the loop detect relay.

This way, only the “Help/Emergency” outbound calls will

activate the relay. Cut one of the “Info” switch wires in

half and connect each end to LDB-3 terminals 5 and 6

as shown in the diagram at the right. Note: The Disable

input is NOT polarity sensitive.

The “Disable” input can be connected to a remote switch,

contact closure, etc. for deactivating the LDB-3’s internal

relay. This can be useful to turn off the controlled device

(strobe light, camera, etc.) Use the diagram shown at the

right. If the relay has been activated by ringing, the switch

will deactivate the relay and ringing

must stop for a minimum of 6 sec-

onds before the relay can be re-

activated from a new incoming call.
