Opal Heat Detector

The Notified Opal Heat Detectors are fixed temperature analogue addressable sensors employing low mass thermistors and microprocessor technology for fast response and linear temperature sensing. Their linear response allows these sensors to be used to signal temperatures over the range of 58°C (class A1S). The detectors 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).

With the implementation of the advanced protocol, any model can be software configured to be either a fixed 58°Cor a 58°C with rate of rise device. The sensing elements of all three heat sensors are panel controllable through the advanced protocol so the sensitivity thresholds of each element can be changed by the panel offering the ability to customize the device for the changing use of the area it is protecting. The detectors have 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.
