The Siemens XTRI-M Intelligent Interface Module is designed to provide the means of interfacing direct shorting devices to the fire alarm control panel (FACP) loop circuit. The module uses one (1) address on the loop.
Also, each Siemens XTRI-M interface module provides the “built-in” ISOtechnology feature-intelligent dual isolation meeting NFPA 72 Class X wiring requirements. Up to 252 isolation-ready devices per loop as well as in mixed mode a maximum of 30 non-isolated devices between isolated devices (wired in polarity-insensitive mode). Additionally, the devices between isolators can either be ‘H’-series or the more contemporary ‘X’-series detection devices.
Model XTRI-M incorporates ISOtechnology – the configurable, built-in dual isolator feature. Additionally, an XTRI-series interface module supports True Class – X operation meeting current NFPA 72 SLC performance requirements for short circuits while providing reliable alarm communication with the Siemens FACP.
The isolation feature on a Model XTRI-M Mini Module provides the location of the `Trouble’ command sent to the FACP. When a short occurs, the panel can identify the fault automatically. Concurrently, the module recognizes the location of the fault (in front of the device or behind the device).
