GB-313 series ror/fixed temperature heat detectors
GB-313 series heat detectors provide an effective solution and fast response in case of intense fires under rapid temperature rise situation. the gb-313 series heat detector operates by using a matched pair of thermistors to sense heat.
the gb-313 range is classified according to EN54-5 as rate-of-rise and fixed temperature detectors. fixed temperature thermistor will respond only when the alarm threshold is reached. rate-of-rise thermistor measures the rate of increase in temperature.
