3.18.2 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. See Table 3-8 for resistance limitations for the connecting circuit.
Note, that if more than four (4), LDM-7100 modules are installed, an external
regulated and power-limited power supply Listed for use with fire protective
signaling units is required.
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.
