• The NFS2-640 intelligent Fire Alarm Control Panel is part of the ONYX® Series of Fire Alarm Controls from NOTIFIER. In stand-alone or network configurations, ONYX Series products meet virtually every application requirement.
• The NFS2-640’s modular design makes system planning easier. The panel can be configured with just a few devices for small building applications, or networked with many devices to protect a large campus or a high-rise office block. Simply add additional peripheral equipment to suit the application. A host of other options are available, including single- or multichannel voice; firefighter’s telephone; LED, LCD, or PC-based graphic annunciators; networking; advanced detection products for challenging environments; wireless fire protection; and many additional options.
• NOTE: Unless called out with a version-specific “E” at the end ofthe part number, “NFS2-640” refers to models NFS2-640 and NFS2-640E; similarly, “CPU2-640” refers to models CPU2-640 and CPU2-640E.
