The Siemens XTRI-R Intelligent Interface Modules provide a seamless way to connect direct shorting devices to the fire alarm control panel (FACP) SLC. Each module occupies one address on the loop. Key Features Dual Isolation TechnologyEach Siemens XTRI-R module integrates intelligent dual isolation technology, which complies with NFPA 72 Class X (Style 7) wiring standards. As a result, the system supports up to 252 isolators per loop, with a maximum of 30 devices placed between isolators. These devices can include both ‘H’-series and ‘X’-series detection devices. Improved DiagnosticsThe built-in isolators enhance diagnostics by pinpointing problems, including shorts. Consequently, this feature allows technicians to identify issues quickly, improving the efficiency of repairs and minimizing downtime. Configurable ModesYou can configure the XTRI-R module in either an isolator (polarity sensitive) or non-isolator (polarity insensitive) mode. When set as an isolator, the module functions as both an in/out device and an isolator, offering greater flexibility. Advanced TroubleshootingCompatible panels aid in troubleshooting by identifying when the XTRI-R module is incorrectly wired in polarity-insensitive mode, even though it is configured as an isolator. Thus, technicians can resolve wiring issues with ease. Relay ControlBy using an addressable ‘Form C’ relay, the XTRI-R relay and contact device input are controlled at the same address. This relay enables independent control from a Siemens-compatible FACP and is typically used to control or shunt external equipment.
