Addressable VIEW Laser Smoke Detector

Specification of

The Notifier FSL-751 VIEW® Laser Detector is a revolutionary
advance in early warning smoke detection technology. The
unique design of this laser detector allows smoke detection
sensitivity that is up to 50 times higher than present photoelectric technology, when combined with enhanced intelligent
sensing algorithms in the Notifier AFP-300, AFP-400, NFS-
640, NFS2-640, NFS-320, NFS-3030 or NFS2-3030 control
panels. Because of this high sensitivity, the FSL-751 can provide very early warning of slow smoldering fires. Its performance is comparable to present aspiration technology, at a
substantially lower installed cost.

The FSL-751 uses an extremely bright laser diode, combined
with special lens and mirror optics (U.S. patent pending), to
achieve a signal-to-noise ratio that is much higher than traditional photoelectric sensors. In addition, the tightly focused
light beam, combined with the intelligent sensing algorithms,
allow the system to differentiate between dust and smoke particles. Because of this differentiation, the FSL-751 can be set
to extremely high sensitivity, yet can reject false signals
caused by larger airborne particles such as dust, lint, and
small insects.

The FSL-751 is an intelligent (analog/addressable) detector.
Using CLIP mode, up to 99 FSL-751 detectors may be
installed per loop. On FlashScan® systems (NFS-640/NFS2-
640/NFS-320/NFS-3030/NFS2-3030), up to 159 addresses
are available. The FSL-751 may be mixed in any combination
with other Notifier intelligent sensors on the same loop and is
quickly installed using the panel autoprogram feature. The
FSL-751 has dual bi-color LEDs, which blink green in normal
operation and illuminate steady red in alarm.
