SECTION 1: INTRODUCTION
1.1 Product Overview
The Model FS24X™Detectors sense the WideBand IR™
radiant energy of blackbody particulate and molecular
emissions generated by BOTH hydrocarbon and non-
hydrocarbon flames and fires. The WideBand IR spectral
radiant energy wavelengths sensed by the Quad (4) sensors
span from approximately 0.4 to 5.5 microns for the FS24X.
The Model FS24X Multi-Spectrum Fire and Flame Detectors
are designed and Factory Mutual approved for use in Class I,
Div. 1 and 2, Class II and Class III; Class I, Zone 1 AEx d
and Ex d IIC Hazardous Locations and ATEX Certified Ex db
IIC (T4-T6) and Ex tb IIIC (T4-T6) Flameproof (Figure 1-1 &
Figure 1-2).
The FS24X Detectors are available in copper-free Aluminum
or 316 Stainless Steel enclosure. The FS24X Detector
electro-optical electronics module (puck) is enclosed in a
field-replaceable black, hard anodized aluminum puck that
provides superior ruggedness, handling, ease of installation,
and protection against EMI/RFI.

FS24X 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 hard-wired 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).

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).
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. The installation shall take into account that the FS24X orientation should be with the base horizontal
(see Figure 2-1) as the view angle in this direction is 90°. The vertical angle is 90°.
Horizontal Field of View
Figure 2-1
FS24X Graphical View
3. 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).
4. 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.
5. The Model SM4 is a 316 Stainless Steel Swivel Mount designed for the Honeywell Analytics 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.
6. Avoid mounting the Detectors in areas where temperatures exceeds the specified operating
temperature range (see Sections 1.2.3 & 1.2.5).
7. 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 2-3).
b) Install an approved conduit trap or drain, if required to meet hazardous area classifications per
NFPA 70: National Electrical Code, latest revision.

Mounting Instructions (continued)
Note the following Precautions:
1. UDo not touchUthe 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 2-5).
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.

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.
1. Loosen the set screw on the enclosure lid
(see Figure 2-6).
Figure 2-6
2. Turn counterclockwise (CCW) to unscrew
the enclosure lid (see Figure 2-7).
Figure 2-7
3. Loosen the three captive screws on the
Detector Module puck (see Figure 2-8).
