2 Product Overview
The SPECTREX Model 20/20ML UV/IR Flame Detectors are designed to sense the
occurrence of fire and flames and subsequently activate an alarm or an
extinguishing system, directly or through a control circuit, for maximum fire
protection. They use the innovative technology of advanced digital signal
processing to analyze the dynamic characteristics of fire.
Detection performance is controlled by a microprocessor and easily adapted to all
environments, applications, and requirements.
These versions of the UV/IR detectors are designed for location in non-Ex/safe
areas. The programmable functions are available through an RS-485 port used
with a standard PC and software supplied by SPECTREX.
To use the Host software and to change the required functions, refer to Manual
TM784050 for instructions.
Warning:
The detector is not field-repairable due to the meticulous alignment
and calibration of the sensors and the respective circuits. Do not
attempt to modify or repair the internal circuits or change their
settings, as this will impair the system’s performance and void the
SPECTREX product warranty.

2.2 Principles of Operation
The Model 20/20ML UV/IR Flame Detector is an electronic device designed to
sense fire and flames and subsequently activate an alarm or an extinguishing
system directly or through a control circuit.
Page 16
Product Overview
16 SharpEye™ UV/IR Mini Flame Detector User Guide
The UV-IR Radiation Flame Detector is a dual spectrum optical detector sensitive
to 2 separate ranges of the radiation spectrum, both of which are present in fires.
The detector monitors the protected area, by measuring the radiation intensity in
it, within 2 frequency ranges of the electromagnetic spectrum, namely the UltraViolet (UV) and the Infra-Red (IR).
The detector integrates 2 dependent channels in which appropriate detection
pulses are registered and further analyzed for frequency, intensity, and duration.
2.3 Sensing Elements
The IR sensor is sensitive to radiation over the range of 2.5–3.0µ.
The IR channel will register a detection signal at the appropriate level in the
following scenarios:
• When the IR sensor is exposed to radiation in the appropriate frequency
range
• When there is an intermittent gleam pattern characteristic to a flickering fire
• When a preset threshold and time duration are reached
The UV sensor is sensitive to radiation over the range of 0.185–0.260µ. The UV
channel incorporates a special logic circuit that eliminates false alarms caused by
solar radiation and other non-fire UV sources. Furthermore, the UV channel
sensitivity is stabilized over the working temperature range.
2.4 Modbus RS-485
For more advanced communications, 20/20ML has an RS-485 Modbus-compatible
output that provides data communications from a network (up to 247 detectors)
to a host computer on a universal controller for central monitoring.
This feature enables reconfiguration of factory settings, eases maintenance, and
allows local and remote diagnostics.
2.5 Types and Models
The 20/20ML is available with a St. St. 316L housing.
The output is via either a connector (socket) or a cable tail (up to 2m long).

3 Performance
3.1 Detection Sensitivity
Detection sensitivity is the maximum distance at which the detector will reliably
detect a specific size of fire and a typical type of fuel (standard fire).
3.1.1 Standard Fire
A 1ft2/0.1m2 gasoline pan fire with a max. wind speed of 6.5ft/sec / 2m/sec.
3.1.2 Sensitivity Ranges:
The detector has 2 user selectable sensitivity ranges. For each range there are 2
response levels:
• Warning (pre-alarm)
• Alarm
The detection distance for the warning level is approximately 10% higher than
the alarm distance. Alarm response times for a “standard fire” at a specified
range are shown here:
• Sensitivity Range (ft/m): 50/15
• Response Time (sec): 5
For some typical ambient conditions, the Zeta parameter as defined in NFPA 72
for the 20/20ML detector is 0.01 (1/m).
Note:
Zeta parameters may vary significantly with changes in temperature,
air pressure, humidity, visibility conditions, etc.

The detector will be in its BIT Fault state until it has passed a successful BIT and will stop
approximately 3 seconds after the fire is no longer detected.
4.2.1 Optional Latching
The detector has an optional latched alarm output capability, which operates
according to the programmable function. If selected, upon the detection of a fire,
the detection signal is latched until manually reset (disconnecting the power
supply or performing a manual BIT). Latching affects the Alarm relay, 4–20mA
output, and the Alarm LED.

Operation
TM767100 Rev. (Ad), May 2019 25
4.2.2 Built-In-Test
When the programmable function Alarm BIT is set at Yes, a successful manual
BIT will activate the Alarm relay for 3 seconds and the 4–20mA output will
provide 20mA for 3 seconds
4.3 Detector Mode Setup
4.3.1 Detector Settings
See Detector Default Setup on page 26 for default factory settings.
The 20/20ML incorporates several functions that can be set by the customer
using SPECTREX Host software, which will be supplied for each detector
shipment.
The Host software enables you to change functions, as described in Detector’s
Various Functions on page 25. Refer to Manual TM784050 for programming
instructions.
4.3.2 Detector’s Various Functions
4.3.2.1 Sensitivity Ranges
The detector offers 2 sensitivity settings. The detection distance for the alarm
level is 50ft/15m from a standard fire.
4.3.2.2 Alarm Delay
The detector is equipped with an alarm delay option, which provides
programmable time delays of 0 to 30 seconds with 8 fixed settings: 0, anti-flare,
3, 5, 10, 15, 20, and 30 seconds.
The alarm delay option will affect the alarm relay and the 4–20mA output.
When an alarm (detection) level condition is encountered, the detector delays the
execution of the Alarm output relay by the specified period of time. The detector
will then evaluate the condition for 3 seconds. If the alarm level is still present,
the alarm outputs will be activated. If this condition no longer exists, the detector
will return to its Standby state. The LED will indicate the warning level during the
delay time only if the fire condition exists.
4.3.2.3 Anti-Flare
Anti-Flare mode is selected to prevent false alarms in locations where fast flares
may be present. The time delay for fire alarm in this mode is from 2.5 to 15
seconds (mostly less than 10 seconds).

4.4 Built-In-Test
4.4.1 General
The detector’s Built-In-Test (BIT) checks the following:
• Electronic circuitry
• Sensors
• Window cleanliness
The detector can be set to perform the BIT automatically and manually, or
manually only.
4.4.2 Principles
If the result of a BIT is the same as the current status of the detector (Normal or
BIT Fault), the detector’s status is unchanged. If the result of a BIT differs from
the current status of the detector, the detector’s status is changed (from Normal
to BIT Fault or from BIT Fault to Normal).
Note:
In BIT Fault status, the detector can continue to detect a fire.
4.4.3 Automatic and Manual BIT
4.4.3.1 Automatic BIT
The detector automatically performs a BIT every 15 minutes.
A successful BIT does not activate any indicator:
• The fault relay remains closed (Normal).
• The LED continues to flash (1Hz) at green.
• The 4–20mA output continues to indicate 4mA.
An unsuccessful BIT sequence activates the following:
Page 28
Operation
28 SharpEye™ UV/IR Mini Flame Detector User Guide
• The Fault relay is opened.
• 4–20mA output indicates a BIT Fault (2mA).
• The LED flashes (4Hz) at yellow.
• A BIT procedure will be performed every minute.
4.4.3.2 Manual BIT
Functions as described in Manual BIT Only on page 28. In the case of an
unsuccessful BIT, all outputs will function as described in Manual BIT Only; but
the BIT will be automatically executed every minute. This mode of operation will
continue until a successful BIT has been completed. As a result, the detector will
resume its normal operation.
4.4.4 Manual BIT Only
The BIT is initiated manually by momentarily connecting Pin no. 3 (yellow wire)
with Pin no. 2 (black wire). A successful manual BIT activates the following:
• Fault relay remains closed.
• Alarm relay is activated for 3 sec (only when the Function Alarm BIT is at
Yes).
• 4–20 mA output current will be 20mA (only when the Function Alarm BIT is at
Yes).
• The LED will illuminate at red for 3 sec.
An unsuccessful BIT activates the following:
• Fault relay is opened.
• 4–20 mA output indicates BIT fault condition (2mA).
• The LED flashes (4Hz) at yellow.
Note:
During a manual BIT, if the Function Alarm BIT is at Yes, the Alarm
relay will be activated and the 4–20mA outputs will initiate 20mA.
Therefore, automatic extinguishing systems or any external devices
that should be activated under actual alarm conditions should be
disconnected during a BIT.

6 Installation Instructions
6.1 Scope
The SharpEye Model 20/20ML is a self-contained optical flame detector designed
to operate as a stand-alone unit, directly connected to alarm systems or to
automatic fire extinguishing systems. The detector can be part of a more complex
system where many detectors and other devices are integrated through a
common control unit.
This chapter does not attempt to cover all of the standard practices and codes of
installation. Rather, it emphasizes specific points of consideration and provides
some general rules for qualified personnel. Wherever applicable, special safety
precautions are stressed.
6.2 General Considerations
Note:
The detector should be aimed toward the center of the detection zone
and have a completely unobstructed view of the protected area.
Whenever possible, the detector face should be tilted down at a slight
angle to prevent the accumulation of dust and dirt. Do not start an
installation unless all conceivable considerations regarding detector
location have been taken into account.
To ensure optimal performance and an efficient installation, the following
guidelines should be considered:
6.2.1.1 Sensitivity
To determine the level of sensitivity, the following issues should be considered:
• Size of the fire at the determined distance to be detected
• Types of flammable materials
6.2.1.2 Spacing and Location
The number of detectors and their locations in the protected area are affected by:
• Size of the protected area
• Sensitivity of the detectors
• Obstructed lines of sight
• Cone of view of the detectors
Page 34
Installation Instructions
34 SharpEye™ UV/IR Mini Flame Detector User Guide
6.2.1.3 Environment
• Dust, snow, or rain can reduce the detector’s sensitivity and require more
maintenance activities.
• The presence of high intensity flickering of IR sources may affect sensitivity.
6.3 Preparation for Installation
Installation should comply with local codes or NFPA as applicable to flame
detectors. The detector can be installed with the use of general-purpose common
tools and equipment.
1 Verify the appropriate purchase order. Record the detector’s P/N, serial no.,
and the installation date in the appropriate logbook.
2 Open the package prior to detector installation and visually inspect the
detector.
3 Verify that all components required for the detector’s installation are readily
available before commencing the installation. If installation is not completed
in a single session, secure and seal detectors and conduits.
4 For wiring, use color-coded conductors, suitable wire markings, or labels.
12 to 20AWG (0.5mm²–3.5mm²) wires may be used for site wiring. The
selection of wire gauge should be based on the number of detectors used on
the same line and the distance from the control unit, in compliance with
specifications.
6.4 Installation
The detector can be mounted directly on the wall through the 7mm hole (Item 7,
Figure 6), or preferably with the optional tilt mount, Model 787640 (Item 1,
Figure 6).
The tilt mount enables the detector to be rotated up to 60 degrees in all
directions.

Page 42
Operating Instructions
42 SharpEye™ UV/IR Mini Flame Detector User Guide
7.3 Reset
To reset a detector when in its Alarm state:
• Disconnect power
Or
• Initiate a manual BIT
Caution:
Reset only when the optional latching alarm has been selected.
7.4 Functional Testing
Following is a testing procedure for proper functioning of the detector. The
detector can be tested using the manual Built-in-Test or the SPECTREX Flame
Simulator FS-1200.
7.4.1 Manual BIT Test
Momentarily connecting Pin no. 11 (yellow wire) with Pin no. 2 (black wire)
performs a manual BIT.
Caution:
If the function setup Alarm BIT is at Yes, then the Alarm and 4–20mA
output will be activated during a manual BIT. Therefore, automatic
extinguishing systems or any external devices that may be activated
during BIT must be disconnected.
1 Verify that the detector is operating properly.
2 Initiate a manual BIT. After a few seconds the following occurs:
• An Alarm relay will be activated and the 4–20mA output changes to 20mA
for 3 seconds (only if Alarm BIT is at Yes).
• The LED should be a constant red for 3 seconds.
• The Fault relay should stay N.O. during the test.
7.4.2 Testing with Flame Simulator Model FS1200
This test simulates an exposure of the detector to a real fire condition (see
Appendix B:) using Flame Simulator Model FS1200. The detector is exposed to
radiation at the required detection level. As a result, the detector must generate
a fire alarm signal.
Page 43
Operating Instructions
TM767100 Rev. (Ad), May 2019 43
Note:
If the detector is exposed to a flame simulator, the Alarm relay and
4–20mA will be activated during the simulation. Therefore, automatic
extinguishing systems or any external devices, which may be
activated during this process, must be disconnected.
1 Turn on the system and wait up to 60 seconds for the detector to turn to
Normal state and the LED to flash (1Hz) green. If the detector is on, skip this
step.
2 Aim the SPECTREX Flame Simulator Model FS1200 at the detector’s target
point (see Figure 15), in a way that the radiation emitted by it is facing
directly towards the detector. (See Flame Simulator FS-1200 on page 53).
3 Press the operation button once. After few seconds:
• The LED should light a steady red for a few seconds.
• The 4–20mA output should turn to 20mA for a few seconds and then
return to 4mA.
• The Alarm relay should also turn on during this period.
This completes the installation procedure. The detector and system are now
ready for operation.
7.5 Safety Precautions
After powering up, the detector requires hardly any attention in order to function
properly, but the following should be noted:
• Follow the instructions in the user guide and refer to the drawings and
specifications issued by the manufacturer.
