Multi-Sensor is equipped with a built-in smoke sensor and a thermal sensor. The smoke sensor’s primary function is to detect the presence of smoke within its surveillance area. Once the smoke reaches the predetermined alarm threshold level, the sensor promptly triggers an alarm signal to the fire panel, ensuring a timely response to potential fire incidents. Similarly, the thermal sensor measures the temperature within its surveillance area and can detect sudden rises in temperature or abnormal temperature levels. When such conditions are detected, the sensor triggers an alarm signal to the fire panel, alerting relevant personnel to take necessary action.
