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
Class I, Division 1 and 2, Class II and Class III, Ex db IIC,
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.
Figure 1-1

Shown with Copper Free Aluminum Housing
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.

SECTION 2: INSTALLATION
2.1 Mounting Instructions
Consider the following guidelines when selecting Detector location:
1. As with all flame and fire Detectors, avoid areas that contain radiant energy sources (such as radiant
heaters, high intensity lamps, flare-stacks, etc.) in close proximity to the Detector’s field of view.
2. Detectors should not be mounted so that they look up or face the horizon (especially outdoors). Use
a minimum thirty degrees (30°) downward angle with the SM4 swivel mount (see Figure 2-1).
3. Make sure the Detector has a clear, unobstructed view of the threat area. Physical obstructions
between a fire and the Detector may cause the fire to be undetected.
4. The Model SM4 is a 316 Stainless Steel Swivel Mount designed for the FSC Detector housing. The
adapter plate, with the two (2) screw holes (facing away), is attached to the base of the Detector (see
Figure 2-1). The mounting plate, with the four (4) screw holes (facing towards), is used for mounting
the SM4 to a solid surface. Each adjustment increment along an axis is calibrated to 10°. For single
axis adjustments, the center section need not be installed.
5. Avoid mounting the Detectors in areas where temperatures exceeds the specified operating
temperature range (see Sections 1.2.3 & 1.2.5).
6. Detector Conduit Entries
a) If only one conduit entry is used, correctly install and seal the conduit plug on the unused entry,
¾ in. NPT or 25mm (see Figure 2-2).
b) Install an approved conduit trap or drain, if required to meet hazardous area classifications per
NFPA 70: National Electrical Code, latest revision.

Note the following Precautions:
1. Do not touch the sensors’ windows on the front of the
Detector electro-optical electronics module (puck). If touched
accidentally, they should be cleaned following the instructions
listed below (see Figure 2-4).
2. When cleaning the Detector’s sensor windows on the puck, it
is best to use Alcohol or IPA sparingly and a cotton swab.
3. There are no serviceable parts inside the Detector puck. If the
puck is opened up or tampered with, all warranties are voided.

Figure 2-4
CAUTION:Follow static protection procedures while handling the connectors and the wiring
of the Module puck to the Detector. Use a wrist strap connected to earth ground.
2.2 Opening the Detector
It is necessary to remove the Detector Module “puck” from the enclosure to access the field connections.
4. Loosen the set screw on the enclosure lid
(see Figure 2-5).
Figure 2-5
5. Turn counterclockwise (CCW) to unscrew
the enclosure lid (see Figure 2-6).
Figure 2-6
Opening the Detector (continued)
CAUTION: Disconnect power before
unscrewing the Housing Lid.

6. Loosen the three captive screws on the
Detector Module “puck” (see Figure 2-7).
Figure 2-7
7. Slide the Detector Module “puck” out of the
enclosure base (see Figure 2-8).
Figure 2-8
2.3 Detector Connections
The Detector Module puck has a six (6) pin and a ten (10) pin keyed removable connector with screw terminal
female plugs that connect to the two (2) respective male connectors with analog, digital, and relay interfaces
(see Figure 2-9):
•For relay configurations, use the ten (10) pin plug (J2) and its connector.
•For digital and analog configurations, use the six (6) pin plug (J1) and its connector.
