Structure of fixed incremental heat detector Nohmi FDHU002-RHA
FDHU002-RHA Temperature Rate-Increase/Fixed Temperature (FDHU002-RHA) is an Analog/Address-coupled thermostat of the Integlex Multicrest series, The thermocouple uses a proven thermistor to generate Accurate and reliable thermal display, Detector and base (not included) are made of durable eggshell white (pale white) plastic to blend in with the ceiling.
The FDHU002-RHA is UL and ULC listed with a fixed temperature point selectable 57°C to 79°C (135°F to 174°F) and a ramp rate feature. A rate increase operates as temperature increases of 7°C to 8°C (12°F to 15°F) per minute occur. Heat detectors are ideal for installations where earlier heat detection is required. The FDHU002-RHA has two LEDs that allow for 360° viewing, the detector is compatible with any Nohmi base and simply screw on. The FDHU002-RHA is addressed using a handheld programmer or a control panel addressing function.
