TC-7352 series heat detectors provide an effective solution and fast response in case of intense fires under rapid temperature rise situation. TC-7352 series heat detector operates by using a matched pair of thermistors to sense heat.
The TC-7352 is according to GB2423 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. It work on 2 wire and DC24V power.
