Siemens XTRI-D Addressable Dual-Input Module

The Siemens XTRI-D is a compact, addressable dual-input module designed for monitoring two separate sets of conventional alarm initiating devices within Siemens Cerberus PRO and Desigo Fire systems. This module is engineered to monitor circuits of normally-open (N.O.) or normally-closed (N.C.) contacts, providing intelligent and reliable supervision for devices such as security contacts, waterflow switches, or tamper switches.

By integrating two input circuits into a single addressable module, the XTRI-D simplifies wiring and ensures efficient system supervision, enhancing overall fire safety and system integrity in commercial environments.
