Advanced Heat Solutions EA323 Series ROR/Fixed temperature heat detectors

EA323 and HD series heat detectors provide an effective solution and fast response in case of intense fires under rapid temperature rise situation. The EA323 series heat detector operates by using a matched pair of thermistors to sense heat. 

The EA323 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.
