D. Relay Contacts
Normally open and normally closed relay contacts are available on the orange, purple and yellow wires. 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.
E. Switched 12V DC Output
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 the included strobe light or providing 12-15V DC power to
any device that draws less than 350mAmps. The positive side is available on the red wire, and the negative side is on
the black wire. Once all the line and load connections have been made, plug in the 115 V AC wall adapter, and replace
the cover.
F. Disable Feature
By connecting the Disable/Info Switch input of the LDB-3 control mod-
ule to the "Info" switch of Viking's E-1600-20A, E-1600-20A-EWP, E-
1600-52A or E-1600-52A-EWP Emergency Phone, any outbound call
initiated from the "Info" button will not activate the strobe light. 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 the
blue wires on the LDB-3 control module as shown in the diagram at
the right. Note: This Disable input is NOT polarity sensitive.
The "Disable" input can be connected to a switch for remotely dis-
abling/turning off the device (strobe light, camera, etc.) controlled by
the LDB-3. For more information, retrieve Fax Back Document 866.

A. Ring Indication
When the LDB-3 control module detects an incoming ring signal, it activates a set of normally open or normally closed
contacts and turns on the 12VDC output for activating the provided strobe light. With the Ring Cadence mode off (DIP
switch 2 OFF), the relay will activate and the strobe light will flash only during ringing. With the Ring Cadence mode
ON (DIP switch 2 ON), the relay will remain activated and the strobe light will remain flashing between rings.
B. Off-Hook Indication
When the LDB-3 control module detects an off-hook condition (loop current) on the brown and gray wires, it activates
a set of normally open or normally closed contacts and turns on the 12VDC output for activating the provided strobe
light. The relay contacts will remain activated and the blue strobe light will flash during the off-hook condition and will
stop flashing approximately 3 seconds after the phone/terminal device on the brown and gray wires is back on-hook.

Mounting the BLK-3-EWP with the E-1600-20A
The BLK-3-EWP can be used in conjunction with the E-1600-20A Two-Button Emergency Phone
as shown to the far right, however, special installation and mounting is required. Please follow
the steps below when using the BLK-3-EWP in conjunction with a surface-mounted E-1600-20A.
A VE-5x5 surface-mount box is required.
Step 1. Drill or use a knockout punch to provide a .875" diameter hole in the top of the VE-5x5.
Step 2. Make all conduit connections.
Step 3. Make all wire connections to the LDB-3 control module.
Step 4. Install the E-1600-20A as explained in its Technical Practice, Fax Back Document 215.
