Opal SMART2 Isolator Photoelectric/Thermal Detector

The Opal SMART2 Photoelectric / Thermal Multi-Criteria Detectors with isolators uses thermal assistance to give enhanced false alarm immunity and faster response to a wide range of incipient fires. The plug-in unit combines two separate sensing elements that are managed by embedded software to act as a single unit. The thermal detection function combines thermistor technology with a software corrected linear temperature response. In areas where the normal daytime activities may potentially create unwanted alarms, the detectors can be programmed to operate in a “heat only” mode, automatically reverting to full photo-thermal operation during unoccupied periods. The detectors has two integral tri-color LEDs that provide 360° local visual indication of the device status. The LEDs are programmable with static or blinking red, amber and green status indications available.
