Zeta MKII addressable heat detectors provide reliable fire detection where smoke detectors are unsuitable. Designed for commercial and industrial environments, they monitor temperature changes and trigger alarms when preset thresholds are reached. Their addressable design allows each device to be individually identified, improving system control and fault finding. Options include rate of rise detectors for rapid temperature increases, fixed heat CS detectors for stable environments, and standard fixed heat detectors for consistent monitoring. These detectors reduce false alarms in areas affected by dust, fumes or steam and integrate seamlessly with Zeta MKII addressable fire alarm systems, ensuring dependable performance across a range of applications.
