Equipped with a 4-line backlit LCD display, NFG-8 shows real-time detected concentrations, active alarms, and overall system status. Front LEDs and function keys make it easy to interact with the control unit, while the three-position key provides security in management operations.
The control panel has 6 on-board relay outputs (8A at 250Vac), programmable as NO or NC. With the optional NFG-16REL board, management can be extended up to 22 outputs, adapting the system to evacuation, ventilation or visual/acoustic signaling needs.
With a historical archive of 1,000 events, which can be accessed from the display and downloaded to a PC, the control panel offers an effective tool for system control and tracking. Programming is done quickly and intuitively via dedicated software by connecting the PC to the control panel via RS232 or USB.
The control panel is powered by mains (100-240Vac) and can house two 12Vdc 7Ah batteries, ensuring continuity of service even in the event of a blackout. The two protected utility outputs also allow external devices to be safely powered.
