Installation of Optional Modules
LED-10IM - EIA-485 Interface Module
The LED-10IM Interface Module provides an EIA-485 port to support the LED-10 Series Remote Annunciator,
LDM Series Annunciator, AFM Series Annunciator and the ACM-8RF Relay Module and supervises the EIA-485
wiring for open circuits. The LED-10IM mounts to connector J6 in the upper right corner of the main board.
Install the two supplied standoffs into the FACP main circuit board. Ensure that the metal standoff is installed in
the position indicated in Figure 2-14. Carefully align the two connectors and press the LED-10IM module
securely into place. Make certain the pins are properly aligned to prevent bending or breaking of any pins. It is
important that the supplied screw and washer be used to secure the module to the metal standoff. This is necessary
in order to help protect against electrical transients.
LED-10IM Installation
FIGURE 2-14:
LED-10 Series Remote LED Annunciator
The LED-10 Series Annunciator connects to the MS-5210UD via the LED-10IM Interface Module. It is recom-
mended that overall foil/braided-shielded, twisted pair cable with a maximum length of 6,000 feet (1,800 m) @ 18
2
AWG (0.75 mm ) be used. Regulated power can be supplied by the MS-5210UD or a remote UL listed filtered,
regulated power supply such as the Fire•Lite FCPS-24.
