Third eneration product with new DEGA desi n
DEGA NBx-EL III w th an electrochem cal sensor
They operate on the principle of chan e of electrical parameters on the electrodes stored in electrolyte, due to
oxidation/reduction reactions of the detected as on it's surface. These sensors have ood selectivity and the ability to detect
very low concentrations of toxic ases.
DEGA NBx-CL III w th a catalyt c sensor (Pel stor)
They operate on the principle of catalytic combustion - as concentration is measured based on the amount of heat released
in a controlled combustion reaction. The reaction is supported by a suitable temperature and the pressence of a catalyst.
These sensors can be used to detect a broad ran e of flammable ases. The sensors are characterized by fast response,a lon
lifetime and hi h stability. A minimum of 10% of Oxy en in the air is required for it's proper function.
DEGA NBx-SL III w th an nfrared sensor (NDIR)
The top quality scannin method. They operate on the principle of infrared spectroscopy. The sensors have excellent selecivity
in or anic matter, do not require any oxy en in the atmoshpere and are resistant to catalyst poisons (sulfur and silicon
compounds) which cause a chan e of sensitivity of catalytic sensors. The sensors are characterized by hi h stability and a lon
lifetime.
DEGA NSx-SL III w th a sem conductor sensor
They operate on the principle of chan es in electrical conductivity of semiconductors by chan in the concentration of the
detected as. Their advata e is a lon lifetime in a clean environment and a wide ran e of different types of ases and vapors.
Their disadvata e is their low selectivity - the sensor lar ly responds to other ases for which it is not calibrated.
DEGA NBx-PL III LCD PID w th a photo on zat on sensor

Assembly and d sassembly of the transm tter
Before assemblin , read the valid instalation standarts EN 60079-29-2 (Selection, instalation, use and maintenance of
detectors for combustible ases and oxy en) and EN 45544-4 (Guildelines for the selection, installation, use and maintenance
of detectors of toxic substances).
Secure that the sensor is reachable by air. The transmitter must be in a free area with no obstacles in its way (furniture etc.)
Ensure that the input of the sensor cannot be polluted by layers of dust or other contamination.
To ma nta n IP protect on the transm tter must be assambled w th the sensor module fac ng downwards.
1. Assembly of the transm tter
The transmitter consists of four parts - the body of the transmitter, the removable sensor and bushin s.
Transmitter assembly procedure is as follows:
a) Disassemble the transmitter with the four hexa on socket screws 3 mm
b) Use a screwdriver to break out holes for the bushin s
c) Mount the transmitter on a flat surface with four 6 mm fasteners in hei ht above the floor with the as entrance
facin downwards, as specified by the detected substance
d) Direct the cable trou h the bushin s
e) Connect the wirin to the terminal block accordin to " Installation of wirin for RS485".
f) Assemble the transmitter with the four hexa on sockets scews 3 mm

2. Replacement of the sensor module
This activity must not be performed when the sensor is ener ized
.
In case of need to replace the sensor module with a new piece, unscrew and remove the
cover. Unscrew a pair of 3 mm hexa on screws on the sensor module and carefully remove
the sensor module so as not to dama e the pins of the sensor unit. Carefully insert the new
sensor module – be careful not to bend the pins! Screw the two 3 mm hexa ons screws and
put back the cover. Screw the cover.
3. Connecting the transmitter via current loop to the controler DEGA UPA II/DEGA UPA III
Connect one transmitter to each channel of the controler as shown in the picture below
4. Connecting the sensor via RS4 5 to the controller DEGA UKA III/DEGA UPA III/UDA III
5. Installation of wiring for RS4 5
Wirin must be done usin bus topolo y and accordin to the RS485 principles.
Maximum number of connected transmitters per controler channel is 16 (may be less dependin on the confi uration of the
controller), while the total len th of the connectin cable (electrical distance between the controller and the last transmitter)
should not exceed 400 meters.
Selectin the appropriate type of cable depends on the fire report and the protocol for determinin external influences.
6. Setting the RS4 5 adress of the transmitter
Each transmitter must have a unique adress within the entire bus, otherwise there will be
communication collisions and malfunctions.
The transmitter adress can either be set internally usin the De aConfi pro ram or usin the
DIP switch on the PCB.
If the position 6 (labeled ADD) is in the ON position, then the adress accordin to the settin
of pins 1-5 is considered. Otherwise the adress set in De aConfi is considered.
The adress can be set from ran e 1-31 usin binary values. A table with DIP settin s for
individual adresses is listed in the attachment "Chart for settin the transmitter adress"

7. Terminating resistor
Accordin to the RS485 specifications, the last device on the bus must be endin with a terminatin
resistor 120R. Plu a jumper on the JP2 connector of the last device on the bus to include the 120R
terminatin resistor. In the default confi uaration the jumper connector is not plu ed.
Transm tter funct ons
The detector's motherboard is equipped by status LEDs, which help in detectin problems durin the installation.
LED „POW“ shines at correct power
LED „ALARM“ shines when the alarm level is crossed
LED „ERROR“ shines in case of malfunction or an unstandard situation
1. Turning on the transmitter
After turnin on the power the LED "POW" starts shinin and the LED "ERROR" starts flashin , indicatin a formin sequence
of the sensor and automatic testin procedures, which can take up to 18 0s dependin on the sensor used. The output of the
current loop is 1 mA. Durin this sequence, testin of internal electronics and stabilization of the sensor in order to eliminate
false alarms after turnin on, is takin place. After completion of the formation, a 4 mA current be ins to flow on the output of
the current loop and the transmitter starts workin accordin to it's settin s.
2. Gas detection
The transmitter continuously measures the detected as concentration in the atmoshpere and converts it's current value into
a 4-20 mA si nal or transmits it's value to the evaluation unit via DEGA protocol (RS485).
3. Malfunction
If a malfunction of the electronics or the sensor is found durin operation, the transmitter will continue transmittin via
current loop 0,5 mA. On the PCB this condition is indicated by the yellow „ERROR“ LED.
4. Monitoring the calibration periods
The transmitter continuously checks the calibration validity of the connected sensor.
After 12 months since the last calibration (Max. calibration interval) the LED "ERROR" starts flashin . The connected sensor
must be calibrated immediately. The transmitter will transmit the information about the endin calibration via current loop.
The transmission will be the followin : 10 s transmittin a 4-20 mA si nal informin about the actual as concentration
followin a 1 second interval of 2 mA current.
Operat on, ma ntenance, nspect on and serv ce of the transm tter
1. Usage limits
To maintain proper operation of the transmitter it is neccesery to respect the fact, that step chan es of humidity,
condensation or rapid chan es of pressure can cause incorrect indication of the measured value. Each sensin technolo y is
suited for different methods of application, which is described below. All sensors are characterized by a smaller or lar er cross-
sensitivity to other ases than those which are set. Therefore before processin project documentation we recommend to
have the air in the deployment area of the detection system analyzed.
a) catalyt c sensors: Trace amount of vapors of silicon compounds and sulfur compounds cause a permanent loss of sensitivity,
which requires recalibration or replacement of the sensor. Lon term crossin of the measurin ran e causes a decrease in
sensitivity. In case of an atmoshpere havin an oxy en content of less than 17%, there will be an underestimaton of the
measured value. In case of an atmoshpere havin an oxy en content of more than 25%, there will be an overestimation of the
measured value.

b) electrochem cal sensors: Constant exposure to toxic ases or short-term exposure to ases, which reatly exceed the
maximum ran e of the sensor, can dama e the electrochemical sensor, which requires recalibration or replacement. Hi h
temperature alon with low relative humidity have a ne ative effect on the sensor's lifetime. In case of an atmoshpere havin
an oxy en content of less than 1 % for lon er than 1 hour, there will be an underestimation of the measured value.
c) nfrared sensors: Vapor acids and alkalis can etch the optical system and distort the measurements. A check or a calibration
may be neccesery.
d) sem conductor sensors: Short-term exposure to ases or vapors of or anic solvents, which reatly exceed the maximum
ran e of the sensor, may dama e the sensor and a recalibration or replacement may be required. In case of an atmoshpere
havin na oxy en content of less than 18 %, there will be an underestimation of the measured value.
e) photo on zat on sensors: the UV lamp or sensor must be replaced re ularly, as its clo in of can cause loss of si nal.
2. Operation
To maintain proper operation of the transmitter it is neccesery to respect the fact, that the presence of certain concentrations
of ases or vapors, other than those for which the sensor is set, can cause an alarm, even if the concentration of the as does
not exceed the set level. Given the ran e of disturbin ases or vapors (diluents, exhaust ases, vapors of or anic substances,
disinfectants, etc.) a enerally allowable concentration of interferin ases can not be determined. Data on cross-sensitivity to
certail ases are included at the apporpriate sensors. Therefore before processin project documentation we recommend to
have the air in the deployment area of the detection system analyzed.
3. Operation/Maintenance
In case of contamination the surface can be cleaned with a sli htly moistened cloth.
The seonsors have a different lifetime dependin on the sensin technolo y used, and environmental conditions.
Characteristics of the sensors vary over time. Therefore it is required to perform re ular checks and calibrations, which can be
done in two ways:
a) 1 x every s x months carry out a „cal brat on“ and funct onal control - adjust the sesitivity of the sensor usin
calibration as and check the functionality of the system. The exact interval depends on the purity of the environment,
required accuracy and the occurrance of disturbin ases in the atmoshpere.
b) 1 x every twelve months carry out a „cal brat on“ - adjust the sesitivity of the sensor usin calibration as and check the
functionality of the system. The exact interval depends on the purity of the environment, required accuracy and the
occurrance of disturbin ases in the atmoshpere. Also carry out a „funct onal control" 1 x every three months -
checkin the function of the entire detection system usin a test as, which does not exceed the ran e of the sensor.
We recommend usin as intended for laboratory use.
For the „funct onal control“ do not use means for test ng f re alarm detectors!
Perform calibration only at certified service centers with a valid certificate of competence or the manufacturer.
