DC-M9103 (UL) Conventional Fixed Rate of Rise Heat Detector

DC-M9103 (UL) Conventional Fixed Rate of Rise Heat Detector

The DC-M9103 (UL) rate-of-rise and fixed temperature heat detector, manufactured by GST, is a fire detection device designed to identify sudden increases in temperature or when the ambient temperature exceeds a fixed threshold. This product integrates a microprocessor, ensuring stable and reliable operation in fire detection. It is an ideal choice for conventional fire alarm systems, providing early fire detection and enhancing the safety of buildings.
