EST SIGA-HRD Intelligent Addressable Heat Detector

The EST SIGA-HRD is an intelligent, addressable heat detector engineered for use with EST fire alarm systems. Using advanced thermal sensing technology, the SIGA-HRD provides fast, reliable detection of abnormal temperature changes caused by fire in environments where smoke detection may not be ideal, such as kitchens, garages, or mechanical rooms.

This detector is built for commercial building safety, offering intelligent detection for robust fire protection. It features a durable design and seamless integration with EST's addressable system protocols.
