SECTION 1: INTRODUCTION
1.1 Product
Overview
The Model FS20X
™
Detector senses the Ultraviolet and
WideBand IR™ radiant energy of blackbody particulate and
molecular emissions generated by both hydrocarbon and non-
hydrocarbon flames and fires. The WideBand spectral radiant
energy wavelengths sensed by the Quad (4) sensors span
approximately 0.185 to 0.26 microns and 0.4 microns to 3.5
microns for the FS20X Detector.
The Model FS20X Multi-Spectrum Fire and Flame Detector is
designed and Factory Mutual approved for use in Class I,
Division 1 and 2, Class II and Class III; AEX d/Ex d IIC, and
ATEX/IECEx Ex db IIC, Ex tb IIIC Hazardous Locations (
see
Figure 1-1
).
The FS20X Detector is available in copper-free Aluminum or
in 316 Stainless Steel enclosure. The FS20X Detector
electro-optical electronics module (puck) is enclosed in a
replaceable black, hard anodized aluminum puck that
provides superior ruggedness, handling, ease of installation,
and protection against EMI/RFI.
