The NOHMI 027173, also known as the FDPJ206-D-X model, is a highly reliable fixed temperature heat detector designed for use in commercial and industrial fire alarm systems. It activates an alarm when the ambient temperature reaches a pre-determined fixed point (70°C), making it ideal for environments where smoke detectors may cause false alarms, such as kitchens, boiler rooms, or dusty areas. Its low-profile design allows for discreet installation, while the built-in alarm indicator LED provides clear visual confirmation of its status. Engineered for durability and long-term stability, this detector is an essential component for comprehensive fire protection strategies.
