SIEMENS XTRI-D

Siemens XTRI-D, The Siemens – Fire Safety XTRI-series Intelligent Interface Modules are designed 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. Each XTRI-series 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 polarityinsensitive mode).
Additionally, the devices between isolators can either be ‘H’-series or the more contemporary ‘X’-series detection devices. Siemens XTRI-D, The Siemens – Fire Safety XTRI-series Intelligent Interface Modules are available in three (3) individual types: One (1) Dual-Input: XTRI-D and Two (2) Single-Inputs: XTRI-R (with relay) | XTRI-S − The single-input versions are each designed to monitor a normally open (N.O) or (N.C) normally closed dry contact XTRI-D | XTRI-R | XTRI-S inco
