Wiring for Lamp/LED
• All LEDs must be located in the same room as the LDM modules.
• For 5 volt output use a 680 ohm, 1/4-watt resistors for each point if
using 2 mA LEDs.
• For 24 volt output use a 10K ohm, 1/4-watt resistors for each point if
using 2 mA LEDs.
• LEDs: use red for alarm points, yellow for trouble points and green
for output points.
• Use the cables supplied in the cable kit to wire connectors on LDM.
The figure below illustrates LEDs being powered by the 5 volt output from
LDM-32F, J11 pin 1.

The figure below illustrates LEDs being powered by the 24 volt output from
LDM-32F, J9 pin 3.
