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).
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.
2. Loop/Off-hook Indication Only
Place DIP switch 1 OFF and DIP switch 3 ON. In this configuration, the E-1600-BLT will only flash the strobe light
while off-hook (while the emergency phone is in use).
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.
B. 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.

C. 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.
