Information About NFS-320

The NFS-320 is a modular addressable fire alarm system capable of supporting up to 318 devices across one Signaling Line Circuit (SLC), with flexible configuration for small to mid-sized buildings or as a node in large campus applications. Its support for up to 159 detectors and 159 modules (manual stations, relays, control modules) ensures high adaptability. Equipped with a 6.0 A power supply, four Class A/B NACs, EIA-485 communication, and FLASHSCAN® high-speed polling, the NFS-320 offers rapid, precise detection and response. Features like auto-programming, VeriFire® tools compatibility, PAS pre-signal, and onboard annunciators enhance functionality, while the robust built-in transient protection and Boolean logic controls ensure system integrity under demanding conditions.

Key Features:

• FlashScan® High-Speed Polling: Polls 318 devices in under two seconds with activation for 159 devices in five seconds.
• Detector Compatibility: Supports up to 159 intelligent detectors and 159 modules (relays, monitor/control).
• Power Supply: 6.0 A with four Class A/B NAC circuits for strobes and notification devices.
• Built-In Display and Keypad: 80-character backlit LCD with system/programming QWERTY keypad.
• VeriFire® Tools: Offline programming and reporting tool for diagnostics, programming, and logs.
