Morley IAS Advanced Intelligent Addressable Thermal Detector

The detector uses the thermister and microprocessor technology to provide an alarm when the rate of rise in temperature exceeds 10°C/minute (typical) or if the temperature exceeds a threshold of 58°C response Class A1R). The detector has two integral red LEDs that provide 360° local visual indication of the device status. *Do not install detectors in locations where normal ambient temperature exceeds 50° C.
