2Product 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.
2.1 Technical Description
•Detection Range: up to 50ft/15m for a 1ft2/0.1m2fire
•Two Response Levels: Warning and detection

•Microprocessor Based: Digital signal processing
•Built-In-Test (BIT): Manual and automatic (see Built-In-Test on page 27)
•Electrical Interface:
•Dry contact relays
•Communications network RS-485
•4–20mA output
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.

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 Ultra-
Violet (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).

3Performance
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 1ft2/0.1m2gasoline 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.

Performance

3.1.3 Other Fuels
The detector will react to other types of fires as follows:
•Pan fire size: 1ft2/0.1m2
•Maximum wind speed: 6.5ft/sec / 2m/sec
•Maximum response time: 10 sec
