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
Div. 1 and 2, Class
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.

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

Installation Guide and Operating Manual

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.

Detector Connections (continued)

ATTENTION: FSX Power-Up – After the application of 24 VDC input power or resetting the Detector,

wait a mimimum of (thirty) 30 seconds to allow the Detector’s sensors to normalize to
the environment’s spectral background conditions.

FSX Testing - As with any intelligent flame or fire Detector, please wait a minimum of

thirty (30) seconds between tests (i.e., butane lighter, FSC test lamp, or test fires) to
allow the Detector’s sensors to fully normalize to the spectral background conditions.

Changing the Detector Settings – To activate changes to the settings using SW1,

1. Verify that the external 24 VDC input power is turned UOFFU before connecting the Detector.

2. Avoid wire splices whenever possible. If wire splices are required, solder and properly insulate them.

Good wiring practices simplify installation, improve reliability, and facilitate maintenance.

3. For applications requiring analog/digital communications, please refer to Section 3.2 of this

Instruction Manual.

SW2 and SW3, reset the Detector by cycling (OFF, then ON) 24 VDC input power.

2.4 Installation Practices

UFor installations in a Hazardous Classified Area, consult the National Electric Code Handbook, Articles 500

through 517 for the proper installation practices. For locations outside of the United States, observe local
and/or regional regulations.

Model FS24X911-24-5 detectors must be connected to control panels meeting the requirements of either
NFPA 71 or the local authority having jurisdiction.

IMPORTANT

does NOT provide protection against the ingress of moisture. It is necessary to obtain an approved material
to apply to the threads in order to maintain the “weatherproof” integrity and satisfy local/regional regulations.

UBefore completing the installationU, check that the Detector is configured correctly for the specific

application. The FSX Detectors Factory Default Settings are:

Alarm Relay Outputs are Non-Latching and Normally De-Energized
Detector Range / Sensitivity is Medium (2)

Honeywell 13

U: The Detector’s metal conduit plug by itself cannot make a weather-tight seal. Metal-to-metal

Digital Communication Address is set to 127

If the application for the Detector requires different settings, refer to Section 3.2 for detailed descriptions.

U

Before applying 24 VDC power to the Detector, make sure

1. Wire connections are correct (Section 2.3). Each wire must be stripped properly to the correct length,

loose wire strands must be removed and each wire must be securely and firmly screwed clockwise in
the connector.

2. If using conduit, ensure a proper conduit seal, (appropriate for the area classification), has been

installed and

Uall measures to prevent moisture ingress have been takenU.

3. Consult the manufacturer for dimensional information on the flameproof joint specifications.

4. The FSX Detector is securely mounted and has an unobstructed view of the area of coverage

(Section 2.1).

5. The Detector window is unobstructed and clean.

6. To ensure optimum performance, shield the detector face from intense bright light sources when first

energized.

The Detector is now ready for Power-Up.

Default Setting is used (Section 3.2).

During Start-Up and Commissioning, DISABLE all outputs from the Detector to any control panels or control

devices. As with any flame and fire detector, after the Detector(s) is powered, perform an external Detector
test “end to end”. Using an external hand-held test lamp ensures that the Detector has a clear unobstructed
view of the threat area and the wiring is correct to the control panel or device.

Note: Honeywell Analytics FSX Detectors feature an automatic built-in “through the lens” test that

verifies the cleanliness of its viewing window lens and test its internal electronics and
software. As with any any optical fire and flame detector, this does not constitute a fully
functional “end to end” test as these types of internal self-tests only Upartially Ucheck and test
the operational readiness of a detector.

In order to test the full functionality and operational readiness of UanyU fire or flame detector

“end to end”, without starting a real fire (which is not permitted in hazardous areas), it is
necessary to test the detector(s) with an external test lamp.

Using a test lamp is the UonlyU non-hazardous and safe method to test any flame or fire

detector’s sensors, internal electronics and its alarm activation software, viewing window
lens cleanliness, terminal wiring integrity, actual relay activation, and the proper functionality
of any other outputs that are used. Also, since most detectors are installed in a fire alarm
system, this is the only method to test the complete fire alarm system, ensuring all the system
wiring and cabling and system control panel are properly installed.

Additionally, using an external test lamp eliminates the following detector conditions:

1. The fire or flame detector(s)’ window lens being covered up (such as paint, paint over
spray, paint masking material, hanging garments, etc.),

2. Improperly positioned and oriented for coverage of the threat area,

3. Partial or full blockage of the detector’s line of sight by one or more objects (i.e., recently
installed air ducts or pipes, storage boxes, vehicles, etc.) such that the threat area is not
fully protected. Since all optical fire and flame detectors are line-of-sight sensors, they
must be properly positioned and oriented with an unobstructed view of the threat area so
that they can detect flames/fires.

To test the full functionality of a FSX Detector, use the Model TL-1055 or TL-2055 Test Lamp in

the manner prescribed in this Instruction Manual.

Honeywell 14

Installation Guide and Operating Manual

WARNING: Use test lamp model TL-1055 in non-hazardous locations only! For hazardous
locations, use model TL-2055, as described below.

The TL-1055 and the TL-2055 are the only Test Lamps that will activate the FSX Detectors..

Additionally, do not use these Test Lamps to activate other Honeywell Analytics Detectors
(nor any other conventional fire and flame detectors). Do not use other Honeywell Analytics
Test Lamps or non-Honeywell Analytics Test Lamps to test the FSX Detectors.

Figure 2-13

Figure 2-14

TL-2055 Hand Held Test Lamp for Hazardous Areas

TL-1055 Hand Held Test Lamp (NEMA 1)

Remember to disable the outputs, as a full functional test includes activating the ALARM outputs. A
Honeywell Analytics Test Lamp must be used for this test (Section 4.4). Point the Test Lamp directly at the
front of the Detector (on axis as much as possible, within a distance of about 1 to 25 feet). Activate the Test

Lamp by pressing and holding its pushbutton. While watching the red ALARM LED on the face of the
Detector, slowly move the Test Lamp’s boresight to ensure the Detector receives its full intensity. (

UNOTE:

Practicing this technique may help to optimize testing of the FSX DetectorsU). (Sections 3.6 and 4.4).
The Detector’s red ALARM LED will illuminate, usually within three (3) to ten (10) seconds. Also, the ALARM

Relay outputs will activate and the 4-20 mA analog output will change to 20 mA (±0.6 mA).

If the Detector fails to respond within ten (10) seconds, do the following:

1. Wait ten (10) to twenty (20) seconds before performing another test.

2. Check the Distance: verify that the testing distance is between one (1) and twenty-five (25) feet

from the FSX Detector(s).

3. Check Aiming Accuracy: verify that the proper testing technique (as described above) is

followed.

SECTION 3: OPERATION

Figure 3.1 Principle of Operation

Honeywell Analytics’ multi-spectrum and multi-spectral infrared Fire and Flame Detectors are sophisticated,
state of the art, electro-optical digital radiant energy transducers that sense the wideband radiant energy emitted
by fire’s combustion processes that include flames’ molecular emissions and hot particulate blackbody
emissions. Radiant Energy Fire Detectors respond much faster to flames and fires at a longer distance than
other types of conventional photoelectric and ionization smoke and heat detectors because a fire’s emitted
radiant energy travels at the speed of light. Fast response is critical for detecting flaming fires in time to
successfully activate suppression or activate other fire responses such as closing fire doors. Seconds can make
the difference between suppressing a small fire with little or no damage or having a disastrous fire that
overwhelms a suppression system thereby failing to stop the fire.

Infrared (IR) consists of spectral wavelengths longer than the color red. The IR range for fire detection, which is
invisible to the human eye, is from about 700 nanometers to 7000 nanometers (0.7 to 7.0 microns). Honeywell
Analytics’ FS24X Fire Detectors utilize a NearBand IR™ portion of the spectrum from approximately 185 to 260
nanometers and a WideBand IR portion from approximately 0.7 to 3.3 microns. This allows the FS24X Detectors
to sense over 80% of the total radiant “Blackbody Energy” emitted by a fire. Honeywell Analytics’ Detectors
sense and measure the radiant energy generated by a fire at the speed of light.

FSX Detectors also utilize an additional spectral region, the Visible Band, that spans from about 400 to 700
nanometers (0.4 to 0.7 microns.) The Visible Band is used to further discriminate against non-fire false alarm
sources. The Model FS24X Detectors also sense the specific WideBand 4.3 IR™ “Triple IR”. Sensing these
hydrocarbon wavelengths does not inhibit the Detector’s ability to see non-hydrocarbon fires. Built-in
microprocessors use sophisticated Digital Signal Processing (DSP) to accurately distinguish radiant energy from
a real fire and a false alarm source(s). Honeywell Analytics has developed and refined these complex
proprietary and patented WideBand IR algorithms over the last 30 years. These patented algorithms perform
real-time DSP, and precisely analyze the signals in high-resolution frequency and time domains. This decision
making process involves thousands of real-time calculations every second. Honeywell Analytics FS24X
Detectors use solid-state high speed quantum sensors (not heat sensors such as pyroelectric or thermopile) that
all respond to the fire’s radiant energy emissions. The quantum sensors convert the rate of photonic energy
directly into analog electrical signals. These analog signals are then converted to high resolution digital bits for
real-time microprocessor analysis. The Detector microprocessors incorporate random access memory (RAM),
read-only memory (ROM), and non-volatile flash memory. When the microprocessors determine that a real fire
has been detected, the pre-alarm digital sensor data (FirePic™) and the event information are recorded in flash
memory. Depending on the configuration, other actions may include activating one or more status LEDs, relays,
a current loop and sending digital data such as the RS-485 FireBus
determine, based on internal testing and “through-the-lens” testing, that the Detector is not operating correctly, it
records the Fault data and activates the Fault outputs and the yellow status LED. The digital data in the
Detector can be easily accessed with a PC for later analysis and record keeping using Honeywell Analytics’

3.3 LED Status Indicators

The Model FS24X Detector uses three (3) separate, bright LED’s to indicate the Detector’s status.

 The Green LED blinks (flashes) once every ten (10) seconds to indicate a Normal, safe operational

condition (i.e. no Faults and no Alarms). The Green LED is OFF when no external 24 VDC input power is
applied to the Detector.

 The Red LED turns ON when a fire is Alarmed.
 The Yellow LED blinks (flashes) when the window lens is dirty. For all other Fault conditions, the Yellow

LED will turn ON.

3.4 Normal Operation

In Normal operation, the bright Green LED blinks (flashes) every 10 seconds. See Figure 3-4 for the
location of the Green LED. Normal Operation is defined as the Detector with 24 VDC applied and no Alarm
or Fault conditions are present. If one of the 4-20 mA options are selected (Table 3-1), the current, sink or

source, will be 4.0 mA (±0.6 mA). Only the current source mode has been certified to the EN54-10 standard.

3.7 Maintenance

After the FS24X Detector is installed and commissioned, there is little maintenance required. However, a
complete “end-to-end” test of the entire fire detection system should be performed periodically depending on
the application. Additionally, semi-annual or quarterly testing should be performed, using the correct
Honeywell Analytics Test Lamp, to ensure the integrity of the entire fire protection system.

In order to ensure the Detector is operating properly at all times, it may be necessary to establish a periodic
cleaning schedule. Some industrial environments may necessitate more frequent cleaning of the Detector’s
optical surfaces than others.

WARNING – Potential electrostatic charge, wipe enclosure only

4.4 Test Lamps

Some manufacturers claim that their detectors do not need remote testing with an external Test Lamp
because it tests itself. Even though Honeywell Analytics Detectors also perform “through the lens” self­testing and tests themselves, Honeywell Analytics, in compliance with NFPA 72 codes, has developed
portable test lamps for periodical “end-to-end” testing their Detectors remotely. Some of the most important
functions of the remote test lamp are to ensure the Detector’s optical path is not blocked, the Detector is
aimed properly at the fire threat area (that the Detector mounting bracket didn’t move or was accidentally
bumped by someone), and the Detectors alarming circuitry and outputs (i.e. relays, 4-to-20 mA, etc.) function
properly. Internal Detector testing and window lens cleanliness testing cannot insure the Detector is aimed
properly, that its view of the fire scene has not been blocked by something such as a newly installed pipe or
duct, storage box, parked vehicle, etc., and its alarm outputs are functioning properly.

For calibrated testing, in compliance with NFPA 72 Codes for flame detectors, as manufacturers of the FSX
product line, our calibrated testing using our TL-2055 Test Lamp is as follows. If the FS24X set at Highest
Sensitivity alarms to a fully charged TL-2055 Test Lamp at a distance between 1 and 25 feet, then the FS24X
is in normal operating condition.

4.5 Field of View Restrictor

There are some unique and specialized applications that may require a restricted field of view in order to
prevent the Detector from alarming to a known (friendly) fire/flame source (such as a flare stack). The Model
FVR-01 Field-of-View Restrictor is easily modified in the field with a simple hack saw to obtain custom
Detector field-of-views for applications where specific narrow field-of-views are required. The Model FVR-01
Detector accessory has been developed specifically for these unique types of applications. Use of the
restrictor has not been certified to the EN54-10 standard.
