• 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 AWACS™(Advanced Warning Addressable
Combustion 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 cir-
cuits includes a Disable/Enable switch for this feature.
Multi-detector algorithm involves nearby detectors in
alarm decision (U.S. Patent 5,627,515).
Automatic detector sensitivity testing.
Maintenance alert (two levels).
Self-optimizing pre-alarm.
• VIEW® Very Intelligent Early Warning smoke detection
technology:
Revolutionary spot laser design.
Advanced AWACS™ algorithms differentiate between
smoke and non-smoke signals (U.S. Patent 5,831,524).
Addressable operation pinpoints the fire location.
No moving parts to fail or filters to change.
Early warning performance comparable to the best as-
piration systems at a fraction of the lifetime cost.
• Acclimate Plus™ low-profile intelligent multi-sensor:
Detector automatically adjusts sensitivity levels with-
out operator intervention or programming. Sensitivity
increases with heat.
Microprocessor-based technology; combination photo
and thermal technology.
FlashScan® or classic mode compatible with NFS-640.
Low-temperature warning signal at 40°F ± 5°F (4.44°C ±
2.77°C).
• RFX wireless interface system:
Allows protection in areas where the use of wire is un-
economical or unpractical.
Allows communication with wireless smoke detectors
and wireless monitor modules; each RFX unit and de-
tector is assigned an address.
Requires 24 VDC from SLC or system auxiliary power.
• HARSH™ Hostile-Area Smoke Head:
Provides early warning of smoke detection in environment
where traditional smoke detectors are not practical.
The detector's filters remove particulates down to 30
microns in size.
Intake fan draws air into photo chamber, while airborne
particles and water mist are removed.
Requires auxiliary 24 VDC from system or remote power
supply.
• Releasing features:
Ten independent hazards.
Sophisticated cross-zone (three options).
Delay timer and Discharge timers (adjustable).
Abort (four options).
Low-pressure CO
2 listed.
• Voice and telephone features:
Solid state message generation.
Hard-wired voice control module options.
Firefighter telephone option.
