ON
BLK-4 Control Module
Switch 1 Switch 3 Description (see section B)
ON OFF Ring Detection Only
OFF ON Off-Hook/Loop Current Detection Only
ON ON Ring and Off-Hook/Loop Current Detection
Switch 2 Ring Cadence Mode (see section C)
ON Ring Cadence Mode ON - relay remains activated in between rings.
OFF Ring Cadence Mode OFF - relay is activated only during ringing.
Switch 4 Auxiliary Relay Contacts (see section D)
ON Wet (12VDC, 100mA maximum)
OFF Dry (1 Amp maximum @ 30VDC)
C. Ring Cadence Mode
DIP switch 2 is used for switching between different ring detection modes. In the OFF position, the strobe light and
relay will activate only while ring voltage is present and will turn off between rings. In the ON position, the strobe light
and relay will remain on for up to 5.75 seconds after the ringing has stopped. This allows the strobe light and relay 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).
D. Auxiliary Relay Contacts
With DIP switch 4 OFF, normally open and normally closed dry 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.
With DIP switch 4 ON, wet/switched +12VDC (100mA maximum) will be output on the yellow wire and “-” (GND) on the
black wire.
2. Loop/Off-hook Indication Only
Place DIP switch 1 OFF and DIP switch 3 ON. In this configuration, the E-1600A-BLT-EWP will only flash the strobe
light while off-hook (while the emergency phone is in use).
1. Ring Indication Only
Place DIP switch 2 on the 1600A emergency phone board in the OFF position (not shown in the diagram - see
1600A Emergency Phone Board Programming section J). Note: With DIP switch 2 in the OFF position, the
1600A emergency phone board will not answer an incoming call. The LDB-3 control module can monitor for ring-
ing any place along the ringing line. Place DIP switch 1 ON and DIP switch 3 OFF.
3. Both Ring and Loop/Off-hook Indication
If the application requires ring and loop/off-hook indication, place DIP switch 1 and 3 in the ON position.
