Overview
The SenTRI Single Input Module is an analogue addressable interface designed to integrate external devices—such as sprinkler flow switches, pressure monitors or conventional devices without built-in addressable electronics—into the SMS SenTRI fire alarm system.
Each module has a unique address on the system loop, allowing precise identification and monitoring of connected device status. It supports various input types, including normally open and normally closed contacts, making it adaptable to different external signals.
Equipped with a built-in loop isolator, the module maintains system integrity by isolating faults and ensuring continuous communication. This module expands the SenTRI system’s capabilities by enabling seamless integration of non-addressable devices into the addressable fire detection network.
