3.12 ANU-48 Remote LED Driver Connections

The ANU-48 remote LED driver is an optional sub-assembly that provides output to a remote
annunciator which may be located up to 3,000 feet from the panel. Up to fifteen (15), additional
annunciators can be connected. Table 3.12.1 lists the resistance limitations for the connecting
circuit.
NOTE: If more than four (4), ANU-48 sub-assemblies are installed, an external regulated and
power-limited power supply Listed for use with fire protective signaling units is required.

NOTE: WIRING REQUIREMENTS
*Add .003 amp for any LED to be lit for any condition when powered internally. When powered
externally, each output driver circuit provides a maximum of .050 amp with a maximum of 2.4
amp per ANU-48 sub-assembly (48 circuits). Each load must have a minimum resistance of 544
Ohms when the external power is supplied from a PM-9/PM-9G. When powered internally, each
LED must have a current limiting resistor in series to limit the current to .003 amp max per LED.
(Example: 8.87K 1% or 9.1K 5%).
