Overview
The SenTRI 4-Way Mains Rated Input/Output Module with Mounting Box is an addressable interface designed for use with SenTRI fire alarm systems. It provides four programmable channels, each configurable as an input, output or combined input/output for flexible system control.
Each relay is rated at 16 A 230 V AC or 5 A 30 V DC, allowing safe switching of mains-powered equipment such as fans, door releases or fire suppression interfaces. The unit is loop-powered and housed in a robust, flame-retardant ABS enclosure supplied with a mounting box for secure installation.
The module complies with EN54-17 and EN54-18 standards and is ideal for linking fire panels to external plant, HVAC systems or alarms that require reliable, high-capacity interfacing.
