Overview
The SenTRI 4-Way Input Output Module is an addressable interface designed to expand the SMS SenTRI fire alarm system’s connectivity by providing four configurable inputs and outputs. It allows integration of external devices such as control switches, relays or auxiliary alarms, enabling flexible monitoring and control within the fire detection network.
Each input and output can be individually programmed to respond to specific events, enhancing system customisation and functionality. Equipped with built-in loop isolation, the module ensures continuous operation even if a fault occurs on the loop.
Its compact design facilitates installation in various locations, and it operates reliably within a wide temperature range. This module is essential for adapting the SenTRI system to complex fire safety requirements, offering versatile interfacing options for comprehensive fire protection.
