Air2-FD100 does not just detect smoke: it also monitors the level of dust inside the optical chamber, providing an analog indication that can also be consulted via the keyboard. This intelligent function allows maintenance to be scheduled only when really necessary, keeping the system running at peak efficiency. The three-color LED (green, yellow, red) clearly indicates the operating status, including normal operation, cleaning required, alarm, or fault. All settings, including sensitivity and LED deactivation, can be configured via radio, without the need to physically access the device.
