Very Intelligent Early Warning (VIEW®)
Laser Smoke Detector

General

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, NFS­640, 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/NFS2­640/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.

FlashScan® (U.S. Patent 5,539,389) is a communication pro­tocol developed by Notifier for high speed communication
between analog intelligent devices. Intelligent devices commu­nicate in a grouped fashion. If one of the devices within the
group has new information, the panel CPU stops the group poll
and concentrates on single points. The net effect is response
speed greater than five times that of other protocols.

Using the enhanced intelligent sensing algorithms, the intelli­gent sensing system provides drift compensation (meeting UL
requirements as a calibrated sensitivity meter), maintenance
alert (3 levels), selection of 9 alarm levels and 9 pre-alarm lev­els, and report of drift compensation used and recent peak val­ues. The system includes a self-learn sensitivity adjustment to
set the pre-alarm level just above the peak levels sensed over
long periods of time for each detector’s actual environment.
The system includes multi-detector algorithms that permit one
sensor to consider readings from adjacent sensors to provide
faster detection of fires.

Made in the U.S. A.

Recommended Coverage Per Detector

In order to support sophisticated smoke/dust discrimination
algorithms (cooperating multi-detector), it is recommended
that at least two FSL-751 detectors be installed in each room
or enclosed area.

Recommended coverage per detector is 400 square feet
(37.16 square meters).

Installation

The FSL-751 plug-in detector uses a separate base to simplify
installation, service, and maintenance. A special tool allows
maintenance personnel to plug in and remove detectors with­out using a ladder.

Mount base on a box which is at least 1.5" (38.1 mm) deep.
Suitable mounting base boxes include:

• 4" (101.6 mm) square box.

• 3-1/2" (88.9 mm) or 4" (101.6 mm) octagonal box.

• Single-gang box (except relay or isolator base).
