General The NFS-640 intelligent Fire Alarm Control Panel is part of the ONYX® Series of Fire Alarm Controls from NOTIFIER. As a stand-alone small-to-large system, or as a large network, the ONYX® Series of products meets virtually every application requirement. Designed with modularity and for ease of system planning, the NFS-640 can be configured with just a few devices for small building applications, or for a large campus or high-rise application. Simply add additional peripheral equipment to suit the application. Features • One, expandable to two, isolated intelligent Signaling Line Circuit (SLC) Style 4, 6 or 7. • Up to 159 detectors (any mix of ion, photo, thermal, or multisensor) and 159 modules (N.O. manual stations, two-wire smoke, notification, or relay) per SLC. 318 devices per loop/ 636 per FACP or network node. • Standard 80-character display, 640-character large display, or display-less (a node on a network). • Network option – 103 nodes supported (NFS-640, NCA Network Annunciator, or NCS Network Control Station) using wire or fiber-optic connections. • 6.0 amp switch mode power supply with four Class A/B builtin Notification Appliance Circuits (NAC). Selectable System Sensor strobe synchronization. • Built-in Alarm, Trouble, and Supervisory relays. • Up to 64 output circuits per FACP or network node; circuits configurable online. • VeriFire® Tools offline program option. Sort Maintenance Reports by compensation value (dirty detector), peak alarm value, or address. • Autoprogramming and Walk Test reports. • Optional universal 636-point DACT. • 80-character remote annunciators (up to 32). • EIA-485 annunciators, including custom graphics. • Printer interface (80-column and 40-column printers). • History file with 800-event capacity in nonvolatile memory, plus separate 200-event alarm-only file. • Alarm Verification selection per point, with tally. • Autoprogramming and Walk Test reports. • Positive Alarm Sequence (PAS) Presignal. • Silence inhibit and Auto Silence timer options. • March time / temporal / California two-stage coding / strobe synchronization. • Field-programmable on panel or on PC, with VeriFire® Tools program check, compare, simulate. • Full QWERTY keypad. • Charger for up to 90 hours of standby power. • Non-alarm points for lower priority functions. • Remote ACK/Signal Silence/System Reset/Drill via monitor modules. • Automatic time control functions, with holiday exceptions. • Surface Mount Technology (SMT) electronics. • Extensive, built-in transient protection. • Powerful Boolean logic equations. NCA 640-CHARACTER DISPLAY FEATURES: • Backlit, 640-character display. • Supports SCS Series smoke control system in both HVAC or FSCS modes (not UL-Listed for FSCS). • Printer and CRT EIA-232 ports. • EIA-485 annunciator and terminal mode ports. • Alarm, Trouble, Supervisory, and Security relays. FLASHSCAN® INTELLIGENT FEATURES: • Poll 318 devices in less than two seconds. • Activate up to 159 outputs in less than five seconds. • Multicolor LEDs blink device address during Walk Test. • Fully digital, high-precision protocol (U.S. Patent 5,539,389). • Manual sensitivity adjustment — nine levels. • Pre-alarm intelligent sensing — nine levels. • Day/Night automatic sensitivity adjustment. • Sensitivity windows: – Ion – 0.5 to 2.5%/foot obscuration. – Photo – 0.5 to 2.35%/foot obscuration. – Laser (VIEW®) – 0.02 to 2.0%/foot obscuration. – Acclimate Plus™ – 0.5 to 4.0%/foot obscuration. – HARSH™ – 0.5 to 2.35%/foot obscuration. • Drift compensation (U.S. Patent 5,764,142). • Degraded mode — in the unlikely event that the CPU-640 microprocessor fails, FlashScan® detectors revert to degraded operation and can activate the CPU-640 NAC circuits and alarm relay. Each of the four built-in panel circuits includes a Disable/Enable switch for this feature.
