FS20X Fire and Flame Detectors

Product Overview

The model FS20X™ fire and flame detector senses the ultraviolet and wideband
infrared 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 its four sensors span approximately 0.185 to

0.26 microns and 0.7 microns to 3.5 microns.

The 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.

Figure 1. FS20X detectors; aluminum enclosure (left), stainless steel enclosure (right)

The detector is available in a copper-free aluminum enclosure or a 316 stainless
steel enclosure (see Figure 1).

Figure 2. EN54 enclosure

The EN54 version is shown in Figure 2.

The detector’s electro-optical electronics module is a replaceable hard black
enclosure of anodized aluminum that provides ruggedness, handling, ease of
installation, and protection against electromagnetic interference and radio-frequency
interference (EMI/RFI).

FS20X Fire and Flame Detectors

Principle of Operation

Honeywell Analytics’ Multi-Spectrum, Multi-Spectral, and MultiBand™ infrared (IR)
and ultraviolet (UV) fire and flame detectors are sophisticated, state of the art,
electro-optical digital radiant energy devices that sense the wideband radiant energy
emitted by combustion processes that include the molecular emissions and hot
particulate blackbody emissions in flames. Radiant energy fire detectors respond
much faster to flames and fires at a longer distances than conventional photoelectric
and ionization smoke and heat detectors because a fire radiates energy at the
speed of light. High speed of response is critical for detecting flaming fires in time to
activate suppression systems, close fire doors, etc. Seconds can make the difference
between suppressing a small fire with little or no damage or having a disastrous fire
which overwhelms a suppression system and fails to stop the fire.

Infrared light consists of spectral wavelengths longer than red while ultraviolet light
consists of wavelengths shorter than violet. Much of the IR and UV wavelengths
are invisible to humans. The FS20X™ detector operates from approximately 185.
This includes the visible spectrum, from about 400 to 700 nanometers (0.4 to 0.7
microns.) The visible band is used to discriminate against false alarm sources.
The detector senses radiant energy from both hydrocarbon and non-hydrocarbon
fires. Built-in microprocessors use digital signal processing (DSP) to distinguish
between radiant energy from a real fire and that from a false alarm source.
Honeywell Analytics has developed and refined these complex proprietary and
patented WideBand IR and UV algorithms for 30 years, beginning in 1981. 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 FSX™
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 converted to high resolution digital values for real­time microprocessor analysis.

The detector microprocessors incorporate random access memory (RAM), read­only memory (ROM), and non-volatile flash memory. When the microprocessors
determine that a 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, or sending digital data such as the RS-485 FireBusII™ and Modbus.
If the microprocessor determines, based on internal and “through-the-window”
testing, that the detector is not operating correctly, it records the fault data in flash
memory and activates the fault outputs and the yellow status LED. The digital data in
the detector can easily be accessed with a PC for analysis and record-keeping using
Honeywell Analytics’ Windows®-based PC software and FSIM USB Interface Unit.

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-window” self-testing, Honeywell Analytics, in compliance
with NFPA 72 codes, has developed portable test lamps for end-to-end remote
testing.

Internal detector testing and window cleanliness testing cannot ensure that a
detector is aimed properly, that its view of the threat area has not been blocked, or
that its alarming circuitry and outputs (i.e., relays, 4-to-20 mA, open collectors, etc.)
are operating properly. Remote test lamps can perform these functions.

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

Test lamp TL-1055

Model TL-1055 is a general purpose NEMA 1 handheld rechargeable test lamp
designed for testing FSX detectors in non-hazardous locations only. The test lamp
(see Figure 3) is supplied with a universal charger (110 VAC and 220 VAC).

Figure 3. TL-1055 handheld test lamp (NEMA 1)

In normal operation, an FS20X detector will alarm to a fully charged TL-1055 test
lamp at a distance of 1 to 25 feet. This complies with NFPA 72 codes.

14

FS20X Fire and Flame Detectors

N OT I C E

Test lamp TL-2055

Model TL-2055 is designed for handheld testing of FSX detectors in hazardous
locations. The test lamp, shown in Figure 4, is explosion-proof and carries Class I,
Division 1 approval. It also is supplied with a universal, 110VAC/220VAC charger.

Figure 4. TL-2055 handheld test lamp (Class I, Division 1)

In normal operation, an FS20X detector will alarm to a fully charged TL-2055 test
lamp at a distance of 1 to 25 feet. This complies with NFPA 72 codes.

Test lamps do not represent one-square-foot fires; they demonstrate that a
detector will respond to radiant energy sources within its field of view.

Field of View Restrictor

Certain specialized applications 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 (Figure 5) has been developed
for these unique applications. The restrictor can be easily modified in the field with a
hacksaw. Use of the restrictor has not been certified to the EN54-10 standard.

Installation

Installation Practices

For installations in a Hazardous Classified Area, consult the National Electrical
Code Handbook, articles 500 through 517 for the proper installation practices. For

locations outside the United States, observe local and regional regulations.

The detector’s metal conduit plug by itself will not provide a weathertight seal.
To maintain the detector’s weatherproof integrity and satisfy local and regional
regulations, apply an approved sealant to the threads.

Before completing the installation, verify that the detector has been configured
correctly for the application. The factory default settings are as follow:

Before applying power to the detector

● Verify that all wire connections are correct (“Detector Connections” on page

24). Each wire must be stripped properly to the correct length, loose wire

strands must be removed, and securely screwed clockwise in the connector.

● When using conduit, ensure that a proper conduit seal (appropriate for the area

classification) has been installed and appropriate measures to prevent moisture
ingress have been taken.

● Consult Honeywell Analytics for dimensional information on flameproof joint

specifications.

● Verify that the detector is securely mounted, its window is clean, and it has an

unobstructed view of the area of coverage (see “Installation Practices” on page

16).

FS20X Fire and Flame Detectors

Mounting Instructions

Consider the following guidelines when selecting a detector location:

1. Avoid areas containing radiant energy sources (e.g., radiant heaters, high
intensity lamps, flare stacks, etc.) that would be near the detector’s field of view.

2. Install the detector with the base horizontal. The view angle in this direction is 90°
horizontal as shown in the illustration. (The vertical angle is 80°, 45° below the
center line and 35° above it).

Figure 6. FS20X horizontal eld of view

To comply with the requirements of FM3260, the maximum field of view (FoV)
is the angle at which the device can detect a flame at 50% of the maximum
specified distance. Similarly, to comply with the requirements of EN54-10:2002,
the maximum field of view (FoV) is the angle at which the device can detect a
flame at 70% of the maximum specified distance. To comply with the directional
dependence requirements of EN 54-10:2002, an angle of ±40° (80°) from 0°
(where 0° is the orientation of the detector in the same axes as the flame source)
must not be exceeded.

Model SM4 is a 316 stainless steel swivel mount designed for the FS20X
enclosure. The adapter plate (with the two screw holes) is attached to the base
of the detector (see Figure 7). The mounting plate (four screw holes), can be
secured to a solid surface. Angle adjustments are in 10° increments along either
axis. For single-axis adjustments, the center section need not be installed. Do not
mount the detector facing horizontally or above the horizon. Use at least a 30°
downward angle with the swivel mount. This is especially critical outdoors.

3. Provide the detector an unobstructed view of the threat area. Obstructions
between the detector and a fire may prevent it from being detected.

4. Mount the detector in an area where temperatures will not exceed the specified
operating temperature range (see “Environmental” and “Hazardous Area

Classifications” on page 39).

5. Conduit entries

a. If only one conduit entry is used, install and seal the conduit plug on the

unused entry (¾ in. NPT or 25mm, as shown in Figure 8).

Changing Detector Settings

1. Verify that the external 24 VDC power is turned off before connecting the
detector.

2. After applying 24 VDC power, after tests (i.e., butane lighter, FSC test lamp, or
test fires), or after resetting the detector, wait at least thirty seconds to allow its
sensors to normalize to the spectral background conditions.

3. To activate SW1/SW2/SW3 setting changes, reset the detector by cycling the
power.

4. For applications requiring analog/digital communications, refer to “Configuring

the Detector” on page 31.

CAUTION

!

Start-up and commissioning

During start-up and commissioning, disable all outputs from the detector to any
control panels or other control devices.

Testing the detector

After the detector is powered, thoroughly test is using a hand-held test lamp to
ensure the detector has an unobstructed view of the threat area.

Honeywell Analytics FSX detectors feature automatic electronics and internal
software testing every three seconds. This includes a through-the-window test that
verifies the cleanliness of the viewing window. As with all other optical fire and flame
detectors, this does not constitute a fully functional “end to end” test. Self-tests can
only partially check and test the operational readiness of a detector. In order to
thoroughly test the readiness of any fire or flame detector (without starting a real
fire, which is not permitted in hazardous areas), the detector must be tested with a
test lamp. This is the only safe and non-hazardous method to test any detector’s
sensors, internal electronics, alarm activation software, viewing window cleanliness,
terminal wiring integrity, relay activation, and the functionality of all of its outputs.
Since most detectors are installed in fire alarm systems, this is the only method to
test a complete system, ensuring that all of the system wiring and the control panel
are properly installed.

Additionally, using an external test lamp eliminates these conditions:

● The window being covered (with, for example, paint overspray, hanging

garments, etc.)

● The detector being improperly positioned or oriented

● The detector’s line of sight being blocked (i.e., by recently installed air ducts

or pipes, storage boxes, vehicles, etc.) preventing the threat area from being
fully protected. Optical fire and flame detectors are line-of-sight devices so they
must be properly positioned and oriented with unobstructed views of their threat
areas.

28

FS20X Fire and Flame Detectors

To test the full functionality of the detector, use test lamp model TL-1055 or TL­2055 in the manner prescribed in “Test Lamps” on page 15. These are the only
test lamps that can activate FSX detectors. Do not use them with other Honeywell
Analytics detectors or with those of other manufacturers.

1. Disable the outputs (a full functional test includes activating the alarm outputs).

2. Aim the test lamp at the front of the detector (within a distance of about 1 to 25
feet and on-axis as much as possible).

3. Press and hold the test lamp’s pushbutton.

4. While watching the alarm LED on the face of the detector, slowly move the test
lamp’s boresight to ensure that the detector receives its full intensity. Practicing
this technique will help optimize the testing of other detectors. The LED will
illuminate, usually within three to ten seconds. The alarm relay outputs will also
activate and the 4-20 mA analog output will increase to 16mA (±0.6mA), then
20mA (±0.6mA) after the Verify Time is exceeded.

5. If the detector does not respond within thirty seconds:

a. Verify that the test lamp has has been charged sufficiently.

b. Verify that the test-lamp-to-detector distance is between one and twenty-five

feet.

c. Verify that the testing technique described above has been followed. If the

detector still does not respond, contact Honeywell Analytics.

LED Status Indicators

The detector status is indicated by three LEDs:

● Green

● blinking (flashing) once every ten seconds indicates a normal, safe operational

condition (i.e., no faults or alarms).

● off when no external input power is applied to the detector.

● Yellow

● blinking (flashing) when the window is dirty

● on steadily for all other fault conditions

● “Red flashes while FirePic is being stored”New Bullet:

● “Red turns on when a fire is alarmed”

Normal Operation

In normal operation1 the green LED, shown in Figure 27, blinks every ten seconds. If
one of the 4-20 mA options is selected (see “SW1 Configuration” on page 31), 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.

Maintenance

After the detector is installed and commissioned, little maintenance is required.
However, a test of the entire fire detection system should be performed periodically,
depending on the application. Additionally, semi-annual or quarterly testing should be
performed with the appropriate Honeywell Analytics test lamp (TL-1055 or TL-2055)
to ensure the integrity of the system.

Establish a periodic cleaning schedule. Some industrial environments may require
more frequent cleaning of the detector’s window than others.

Clean the detector’s window any time it is dirty or contaminated, every time the
enclosure lid is handled, if the detector fails the built-in test, or if the detector fails an
end-to-end test with the test lamp. If necessary, clean the detector module sensors
whenever the detector has been disassembled.

Use a blast of clean air or an oil-free cloth to clean the enclosure window (oil
degrades the performance of UV detectors). Do not use commercial or silicone­based window cleaning products; they also will degrade the detector’s performance.
Occassional use of a solvent such as 6% isopropyl alcohol is acceptable. No
disassembly of the detector is required for this.

To avoid electrostatic discharge, wipe the enclosure only with a damp cloth.
