Siemens XTRI-R Intel Interface Modules P/n: S54370-b1-a1

The Siemens XTRI-R Intelligent Interface Modules are design to provide the means of interfacing direct shorting devices to the fire alarm control panel (FACP) SLC. All modules take up one (1) address on the loop.

In general, each Siemens XTRI-R interface module provides the “built-in” ISOtechnology feature – intelligent dual isolation meeting NFPA 72 Class X (Style 7) wiring requirements. Up to 252 isolators per loop and up to 30 devices between isolators (wired in polarity insensitive mode). Additionally, the devices between isolators can either be ‘H’-series or the more contemporary ‘X’-series detection devices.

Overall, the built-in isolators improve the diagnostics and location of the problem, including a short. Also, the modules are configurable by a Siemens compatible FACP (or panels) in an isolator (polarity sensitive) or non-isolator (polarity insensitive) mode. When an XTRIseries interface module is configure as an isolator; that module has the capacity of functioning as both an in/out device, as well as an isolator.

Advanced troubleshooting is provide by compatible panels by identifying when an XTRI-series interface module is configure as an isolator, but is wire incorrectly in a polarity-insensitive mode. Through the use of an addressable ‘Form C’ relay, the Model XTRI-R relay and contact device input are control at the same address. The relay and input contact can be control as a separate function from a Siemens compatible FACP. The relay is typically use where control or shunting of external equipment is require.
