Overview
The SenTRI Addressable Optical Heat Sensor with Sounder delivers intelligent, multi-criteria fire detection by combining both optical smoke and heat sensing in one advanced unit. Ideal for a wide range of environments, it provides faster, more accurate detection of fire conditions while minimising nuisance alarms. The integrated sounder ensures clear, localised audio alerts, removing the need for separate sounder units and helping to preserve the aesthetics of the protected area.
Every SenTRI device includes a built-in isolator, improving system reliability and reducing the need for extra components. A monitored input/output line allows flexible configuration as either a fire input or output, potentially eliminating the need for separate interfaces. Designed for convenience and efficiency, the sensor uses the standard first-fix base shared across the entire SenTRI range, cutting installation time and cost. This powerful combination of precise detection, built-in alerting and installation efficiency makes it a smart solution for sophisticated fire protection systems.
