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.
