Description of FDLU019-D-X

The Fixed Temperature Heat Detector (FDLU019-D-X) is designed to work seamlessly with any fire alarm control panel from the IntegleX Multicrest series. Its heat sensor uses a proven thermistor for accurate and dependable heat detection. The detector and its base (not included) are built from durable plastic in an off-white color, which blends effortlessly with the ceiling.Nohmi has introduced advanced circuit integration technology into the FDLU019-D-X. This innovation simplifies the detector’s internal circuitry and significantly reduces the product’s size, making installation more efficient.With a selectable fixed temperature range of 57°C to 85°C (135°F to 185°F), the FDLU019-D-X meets UL standards. This broad range allows flexibility for different installation needs, accommodating various applications with a single unit.
The detector features two LEDs that provide 360° visibility, ensuring you can view status indicators from any angle. It is compatible with Nohmi’s wide range of bases and installs effortlessly by twisting it onto the base. Addressing the FDLU019-D-X is simple and can be done using a handheld programmer or through the control panel’s addressing function.
