3.15.2 LDM-7100 LED Driver Module
Each LDM-7100 LED Driver Module provides 7100 Control Panel output for thirty-three (33),
remote LEDs. Three (3), LDM-7100 modules may be mounted in a single annunciator for a
maximum total of 99 points per annunciator.
The annunciator may be located up to 4,000 feet from the panel and up to four (4), additional
annunciators can be connected, configured identically with the first. Table 3.15.2 lists the resistance
limitations for the connecting circuit.
The module is intended for mounting inside the enclosure of a UL Listed remote annunciator. It
may be mounted by means of mounting screws or stacked using a metal hex standoff kit. Wire
routing and installation methods are to be in accordance with the annunciator installation
instructions.
NOTE:
If more than four (4), LDM-7100 modules are installed, an external regulated and power-
