(not included)
1. Ring Indication Only
Connect the incoming line to the red and green wires with the yellow stripe as shown in the diagram. No phone/terminal device
is required. The LDB-3 control module can monitor for ringing any place along the ringing line.
2. Loop/Off-hook Indication Only
The LDB-3 control module must be placed between the phone line and the phone/terminal device to be monitored. Connect the
incoming line to the red and green wires with the yellow stripe and connect the phone/terminal device to the brown and gray
wires as shown.
3. Both Ring and Loop/Off-hook Indication
If the application requires ring and loop/off-hook indication, the LDB-3 control module must be placed between the phone line
and the phone/terminal device to be monitored. Connect the incoming line to the red and green wires with the yellow stripe, con-
nect the phone/terminal device to the brown and gray wires.
C. Ring Cadence Mode
DIP switch 2 is used for switching between different ring detection modes. In the OFF position, the relay and switched 12VDC out-
put 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 (flashing strobe light)
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).
