INTRODUCTION
The Models ILED-XC (round plate), P/N S54370-B6-A1, and ILED-XW (rectangular plate), P/N
S54370-B5-A1, Addressable Remote Lamps from Siemens Industry, Inc., shown in Figure 1. It
operates as an additional tri-color LED indicator for a device in the device loop circuit of the Desigo
FC2025/FC2050/FV2025/FV2050 and Cerberus PRO FC922/FC924/FV922/FV924 Fire Alarm
Systems. The ILED-X can be used when a device already has an accessory. The ILED-X can be
installed at any location of a device loop, and it remotely indicates the status of the device(s) in that
same loop.

MODE OF OPERATION
The ILED-X must have a unique address when it works in the device loop.
The ILED-X modules support two operation modes: polarity insensitive mode and isolator mode. The
modules can be wired for either mode (refer to Figures 3 and 4). During the isolator mode, the built-in
dual isolators will work at both sides of the module to isolate the line short in front or behind the module.
CONTROLS AND INDICATORS
The LED indicator is capable of flashing any one of three distinct colors: green, yellow, or red, based on
logic in the system configuration tool.
Observe precautions for handling Electrostatic Sensitive Devices.
