The NFS-320 Intelligent Addressable Fire Alarm Control Panel is a versatile solution within NOTIFIER’s ONYX Series, suitable for small to medium-sized applications, from small buildings to large campuses or high-rise office blocks. Its modular design allows for easy configuration with a single Signaling Line Circuit (SLC) supporting up to 318 devices (159 detectors and 159 modules). The panel features FlashScan® protocol for rapid polling and activation, ONYX intelligent sensing for advanced smoke detection, and a 6.0A power supply with four Class A/B Notification Appliance Circuits (NAC). It supports a variety of detectors (ion, photo, thermal, multi-sensor) and wireless devices via the optional FWSG SWIFT Gateway. Networkable with up to 200 nodes in high-speed configurations, it offers robust communication options, including Internet, GSM, and standard UDACT. With a full QWERTY keypad, 80-character display, and VeriFire® Tools for programming, it provides autoprogramming, Walk Test reports, and extensive event history (800 events). Certified for seismic and marine applications, it includes releasing features for up to ten hazards, voice integration with FirstCommand, and powerful Boolean logic for customized operations. The NFS-320 ensures reliability with built-in transient protection, battery support up to 200 AH, and compliance with NFPA-72 standards.
