Lamp/Led Wiring - Honeywell NOTIFIER LDM Series Instruction Manual

Lamp/LED Wiring

below. If this module is used to drive both power-limited and nonpower-limited circuits, connect relays 1 to 16 to power-limited circuits
and connect relays 17 to 32 to nonpower-limited circuits or vice versa. Use an appropriate power-limited power supply which is UL
listed for fire alarm systems to provide power for the power-limited circuits.
4.9 Lamp/LED Wiring
NOTE: All LEDs/lamps being driven by the LDM series must be located in the same room as the modules. Use cable kits for wiring from
connectors on LDM.
• Figure 4.8 illustrates LEDs being powered by the 5V output from LDM-32, J11 pin 1.
• Figure 4.9 illustrates LEDs being powered by the 24V output from LDM-32, J9 pin 3.

Note: All LEDs must be in the same room as the LDM modules.
Point Status LEDs:
Use red for alarm points,
yellow for trouble points, and
green for output points
Use 680 W, 1/4 watt resistors for
each point if using 2 mA LEDs.
