Addressable Switch Interface Modules with Dual Isolators
INTRODUCTION
The XTRI Series Addressable Modules from Siemens Industry, Inc., shown in Figure 1, interface direct
shorting devices to the device loop circuit of the Desigo FC2025/FC2050/FV2025/FV2050 and
Cerberus PRO FC922/FC924/FV922/FV924 Fire Alarm Systems. Refer to the Configuration Tool,
Document ID A6V10315023.
The XTRI modules support two operation modes: polarity insensitive mode and isolator mode. The
module can be wired for either mode (refer to Figures 8 through 13). 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.
The XTRI modules are available in three models. The XTRI-S, P/N S54370-B3-A1, and XTRI-R, P/N
S54370-B1-A1, can monitor a normally open or closed dry contact. The XTRI-S can only monitor and
report the status of the contact, while the XTRI-R incorporates an addressable Form C relay. The
XTRI-D, P/N S54370-B2-A1, is a dual input module that supervises and monitors two sets of dry
contacts.
