ADDRESSABLE HEAT SENSOR WITH ISOLATOR A50HI

The A50HI Addressable Heat Sensor with Isolator is an intelligent fire detection device designed to provide reliable heat monitoring and rapid fire detection in environments where smoke detectors may not be suitable. Built with advanced sensing technology, the detector combines accurate temperature analysis with an integrated short-circuit isolator, ensuring maximum system reliability and continuous operation.

Part of the innovative A50 Series, the A50HI detector features a modern low-profile design and advanced detection algorithms that improve performance while reducing the impact of dust and environmental contaminants. Its thermovelocimetric heat sensing technology enables the detector to respond quickly to abnormal temperature increases and activate an alarm when a static temperature of 60°C is reached during slow-developing fire conditions.

The integrated short-circuit isolator helps protect the addressable loop by automatically isolating faulty sections, ensuring uninterrupted communication between the fire alarm control panel and other connected devices. This makes the A50HI an ideal solution for commercial, industrial, healthcare, educational, and residential applications requiring dependable fire detection.
