Morley HM rate-of-rise heat detector | addressable | with isolator | EN 54-5 A1R

HM-RHSE-I-AP is an analogue addressable rate-of-rise heat detector from the Morley HM series. Its thermistor and microprocessor raise an alarm when the temperature rises faster than typically 10 °C per minute or exceeds 58 °C (class A1R). Two red LEDs show the status from every direction, and the built-in isolator cuts off only the faulty loop section in case of a short circuit. The detector uses the Advanced Protocol and fits the MI/B501AP/IV base. Not for locations where the normal ambient temperature exceeds 50 °C.
