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 outdoors. Additionally, for applications outside of an enclosed wet
bench/tool, use a minimum thirty degree (30°) downward angle with the recommended swivel mount
(Model SM-17).
3. Make sure the Detector has a clear, unobstructed view of the fire threat area. Physical obstructions
between a fire and the Detector may cause the fire to be undetected.
4. The rugged, stable, and calibrated Polypropylene Swivel Mount (SM17) is designed specifically for the
FS17X Detector housings. The mounting clip attaches to the back of the FS17X Detector. The
mounting plate, with the four (4) screw holes, is used for mounting to a solid surface. Each
adjustment increment along an axis is calibrated to 10°. For single axis adjustments, the center
section does not need to be installed.
5. Avoid mounting the Detectors in areas where temperatures exceeds the specified operating
temperature range (see Section 1.2.3).
Figure 2-1
Model SM17 Swivel Mount
There are no serviceable parts inside the Model FS17X Detector housing. If the Detector housing is opened
up or tampered with, all warranties are voided
Note: Do not attempt to modify the Model FS17X Detector as this voids all warranties.
CAUTION: Disconnect electrical power before unscrewing the Housing Lid.

2.3 Installation Practices
For 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.
BEFORE APPLYING 24 Vdc ELECTRICAL POWER TO THE DETECTOR, MAKE SURE U :
1. Wire connections are correct (Section 2.2). 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 the Teflon Sleeve, ensure a proper sleeve seal at the bulkhead, (appropriate for the area
classification), has been installed and U all measures to prevent moisture from entering the
Detector housing have been taken U .
3. The FS17X Detector is securely mounted and has an unobstructed view of the area of coverage
(Section 2.1).
4. The FS17X Detector window is unobstructed and clean.
The FS17X Detector is now ready for Power-Up. On Power-Up, the Fault Relay will change state and the
three front red, blue, and yellow LED’s will flash in a clockwise circular motion signifying the
microprocessors are successfully checking out the sensors and electronics in the Detector Module.
2.4 Start-Up and Commissioning
ATTENTION: FSX Power-Up – After the application of 24 Vdc electrical power or after resetting the FS17X
Detector, a Power-On Self-Test (POST) will be performed automatically. During this time
(approximately 10 seconds) the detector will sequence in a clockwise circular motion through the its
LED’s several times. Wait a mimimum of thirty (30) seconds after the POST is completed to allow
the Detector’s sensors to normalize to the spectral background conditions. Count four (4) Blue LED
flashes to be sure the minmum amount of time has passed before testing the Detector’s response
with a test lamp (TL-2055X or TL-1055X) or a test fire.
FSX Detector Testing - As with any intelligent flame and fire Detector, please wait a minimum of
thirty (30) seconds between tests (i.e., FSX test lamp, butane lighter, or test fires) to allow the
Detector’s sensors to normalize to the spectral background conditions.
During Start-Up and Commissioning, DISABLE all outputs from the Detector to any control panels or control
devices. After the Detector(s) is powered, as with all flame and fire Detectors, conduct an external Detector
test “end to end”. Using our external FSX hand-held test lamp ensures that the FS17X Detector has a clear
unobstructed view of the threat area and the Detector is aimed properly at the fire threat area.

Page 9
Start-Up and Commissioning ( continued )
Note: As with U all U optical fire and flame Detectors, perform a fully functional "end to end" test of the
Detector since the optical path to the fire threat may be obstructed or the detector’s mount
may be damaged (see Section 3.6).
Note: In order to test the full functionality and operational readiness of U any U fire or flame Detector
"end to end", without starting a real fire (which is not permitted in hazardous areas), it is
necessary to test fire and flame detector(s) with an external test lamp.
Using a test lamp is the U only U 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 protection
system, this is the only method to test the complete fire protection system, ensuring all the
system wiring and cabling and system control panel(s) are properly installed.
Additionally, using an external test lamp eliminates the following Detector conditions:
1. The fire or flame Detector(s)' viewing lens being covered up (such as paint, paint overspray,
paint masking material, plastic coverings left by cleaning persons, hanging garments, etc.),
2. Improperly positioned and orientated Detector (or defective or loose mount) 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 fire threat area is
not fully protected. Since all optical fire and flame Detectors are line-of-sight devices, they
must be properly positioned and oriented with an unobstructed view of the fire threat area
so that they can detect fires.
To test the full functionality of a FSX Detector, use either the Model TL1055X or TL2055X Test
Lamp in the manner prescribed in this Instruction Manual.
The TL-1055X and the TL-2055X are the ONLY Test Lamps that will activate the FSX Detectors.
Additionally, do not use these Test Lamps to activate other Fire Sentry Detectors such as the
Models SS2 or SS4 (nor any other conventional fire and flame detectors). Do not use other
Fire Sentry Test Lamps to test the FSX Detectors.

Remember to disable the Detector outputs, as a full functional test includes activating the alarm outputs. A
FSX Fire Sentry Test Lamp must be used for this test (Section 4.3). Point the Test Lamp directly at the front
of the Detector (on axis as much as possible, within a distance of 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. ( U NOTE: Practicing this
technique may help to optimize testing of the FSX Detectors U ). (Sections 3.6 and 4.3). The Detector’s
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 increase to 20 mA (±0.6 mA).
If the Detector does not respond within ten (10) seconds, do the following:
1. Wait thirty (30) seconds before performing another test.
2. Check the Distance: verify that the testing distance is between one (1) and fifteen (15) feet from
the FSX Detector(s).
3. Check Aiming Accuracy: verify that the proper testing technique (as described above) is followed.
4. Make sure the Test Lamp is either a Model TL-2055X or TL1055X Test Lamp.

SECTION 3: OPERATION
3.1 Principle of Operation
Fire Sentry Corporation’s (line of Multi-Spectral and MultiBand™Infrared Fire and Flame Detectors are
sophisticated, state of the art, electro-optical digital radiant energy Detectors 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.
Infrared (IR) consists of spectral wavelengths longer than the color Red. For the FS17X Detector, the IR
spectral range for fire detection, which a large portion of the spectrum is invisible to the human eye, is from
approximately 400 to 3000 nanometers (0.4 to 3.0 microns). Fire Sentry Corporation’s Detectors sense and
measure the radiant energy generated by a fire at the speed of light using high speed infrared quantum
sensors for its IR detectors.
Fire Sentry Corporation’s patented FSX Fire Detectors also use two additional spectral regions, the Visible
Band, that spans from about 400 to 700 nanometers (0.4 to 0.7 microns) and the NearBand IR that span from
about 0.7 to 1.1 microns. The Visible Band and NearBand IR are used primarily to further discriminate against
non-fire false alarm sources.
As with all Fire Sentry Corporation Detectors, the Model FS17X Detector senses radiant energy generated by
both hydrocarbon and 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). Fire
Sentry Corporation has developed and refined these complex proprietary and patented WideBand IR
algorithms since 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. Fire Sentry Corporation’s 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 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 via the RS-485 FireBus II ™. If the microprocessors determine, based on internal testing
and “through-the-lens” 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 be
accessed with a PC for later analysis and record keeping using Fire Sentry’s Windows
®
based PC software
and the FSIM USB Interface Unit.

3.2 LED Status Indicators
As with all FSX Detectors, the Model FS17X Detector uses three (3) separate, bright LED’s (rather than one
tri-colored LED that can be difficult to recognize the different colors outdoors or in a brightly lit area) to indicate
the Detector’s status.
The Blue LED blinks (flashes) once every ten (10) seconds to indicate a Normal, safe operational
condition (i.e. no Faults and no Alarms). The Blue LED is OFF when no external 24 Vdc input power is
applied to the Detector.
The Red LED turns ON when the FS17X goes into ALARM. The Red LED flashes when the FS17X-R
version goes into ALERT.
The Yellow LED blinks (flashes) when the window lens is dirty. For all other Fault conditions, the
Yellow LED will turn ON solidly (see Section 3.5).
3.3 Normal Operation
In Normal Operation, the bright Blue LED blinks (flashes) every 10 seconds. See Figure 3-1 for the location
of the Blue LED. Normal Operation is defined as the Detector with 24 Vdc applied and no ALARM or Fault
conditions are present.

Four (4) Flashes for the FS17X-G (General Purpose Detector)
Six (6) Flashes for the FS17X-R (Radiant Energy Detector)
3.4 ALARM
When an ALARM occurs, the Red LED will turn ON, (factory setting with the Auxiliary relay set to “0”
seconds). See Figure 3-2 for the location of the Red LED.

3.6 Maintenance
After the FS17X Detector is installed and commissioned, virtually no maintenance required in a clean room
environment. However, a complete “end-to-end” test of the entire fire detection system should be performed
monthly or more frequently, depending on the application. Additionally, semi-annual or quarterly testing should
be performed, using the correct Fire Sentry Test Lamp, to ensure the integrity of the entire fire protection
system. (see Note in Section 2.4 and Section 4.3)
Clean the FS17X Detector window:
Each time the Detector is taken out of or put back into to service.
Detector window is dirty or contaminated.
Detector does not respond to an end-to-end test with the Fire Sentry Corporation hand-held portable
Test Lamp (TL-1055X or TL-2055X).
Each time the Detector has been disassembled for wiring or replacement.
Use a blast of clean air or an oil-free cloth to clean the Detector window. Occassionally, the use of a solvent,
such as alcohol is acceptable. No disassembly of the Detector is required.
