SECTION 1: INTRODUCTION
1.1
Product Overview
The Model FS19X™/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 Tri (3) sensors
span approximately 0.18 to 3.5 microns for the FS19X/FS20X
Detector.
The Model FS19X/FS20X Multi-Spectrum Fire and Flame
Detector is designed and Factory Mutual approved for use in
I
Class
, Division 1 and 2, Class
Ex tb IIIC
Hazardous Locations (see Figure 1-1).
The FS19X/FS20X Detector is available in copper-free
Aluminum or in 316 Stainless Steel enclosure. The
FS19X/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.
FS19X/FS20X Detector Field Connectors
The field connections feature two (2) connector choices for the installer:
1. A removable ten (10) pin screw terminal connector (J2) for hardwired relay applications.
2. A removable six (6) pin screw terminal connector (J1) for analog output or RS-485 Digital
Communication applications.
The removable connectors provide quicker installation and allows the Detector enclosure to be installed prior
to the Detector Module (puck).
UField Selectable Configuration Switches
1. The eight (8) pin DIP switch (SW2) is used to select the
Detector's Sensitivity and Relay Options.
2. The ten (10) pin DIP switch (SW1) is used for:
•
Selecting a unique digital address (128 choices).
•
Enabling "Fireball" type fire response
•
Factory Use
3. The ten (10) position Rotary switch allows selection of
the analog and digital communication protocol.
