Rate of Rise/Fixed Temperature Heat Detector
The combination Rate of Rise/Fixed Temperature Heat Sensor (RHA) is a listed Analog/Addressable combination temperature heat sensor compatible with any fire alarm control panel that has the Potter/Nohmi protocol. The heat sensing portion utilizes a proven thermistor for accurate and reliable heat detection. The sensor and base (not included) are made of a durable plastic in an eggshell white (off white) to blend in with the ceiling.
The RHA is UL and cUL listed with a selectable fixed temperature point from 135° to 174° and a rate of rise feature. The rate-of-rise operates when the temperature increases 12-15°F occurs. The heat sensor is ideal for installations needing the earlier heat detection.
The RHA has two LEDs that allow for 360° viewing. The sensor is compatible with any of the Potter/Nohmi bases and simply twists on. The RHA is addressed using the hand held programmer or the control panel addressing function.
