The Fixed Temperature Heat Sensor (FHA) is a listed Analog/Addressable fixed 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 FHA is UL and cUL listed with a selectable fixed temperature point from 135° to 185° Fahrenheit. This broad range allows the installer to cover a wide variety of applications with a single unit.
The FHA has two LEDs that allow for 360° viewing. The sensor is compatible with any of the Potter/Nohmi bases and simply twists on. The FHA is addressed using the hand held programmer or the control panel addressing function.
