DEGA NSx-EL II with an electrochemical sensor They operate on the principle of change of electrical parameters on the electrodes stored in electrolyte, due to oxidation/reduction reactions of the detected gas on it’s surface. These sensors have good selectivity and the ability to detect very low concentrations of toxic gases. DEGA NSx-CL II with a catalytic sensor (Pelistor) They operate on the principle of catalytic combustion – gas 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 presence of a catalyst. These sensors can be used to detect a broad range of flammable gases. The sensors are characterized by fast response, a long lifetime and high stability. A minimum of 10 % of Oxygen in the air is required for their proper function. DEGA NSx-IL II with an infrared sensor (NDIR) Top quality scanning method. They operate on the principle of infrared spectroscopy. The sensors have excellent selectivity in organic matter, do not require any oxygen in the atmosphere and are resistant to catalyst poisons (sulfur and silicon compounds) which cause a change of sensitivity in catalytic sensors. The sensors are characterized by high stability and a long lifetime. DEGA NSx-PL II PID with photoinitiator sensor Sensitive scanning method to detect a wide range of VOC – volatile organic compounds. The sensor non-selectively detects all VOCs in the air already at concentrations in ppm.

Assembly and disassembly of the transmitter
Before assembling, read the valid installation standards EN 60079-29-2 (Selection, installation, use and maintenance of detectors for combustible gases and oxygen) and EN 45544-4 (Guidelines for the selection, installation, use and maintenance of detectors of toxic substances). In explosive environments the electrical installation must be performed according to DIN EN 60079.14 (Electrical installation in hazardous areas). 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 preserve the IP protection, the sensors must be mounted with the sensor down.
1. Assembly of the transmitter
The transmitter consists of four parts – the body of the transmitter, the removable sensor and Ex ,,e” bushings.
Transmitter assembly procedure is as follows: a) Disassemble the transmitter with the four 4 mm hexagon socket screws b) Mount the transmitter on a flat surface with four 6 mm fasteners in height above the floor with the gas entrance facing downwards, as specified by the detected substance. c) Pull the cable through the bushing and, if necessary, secure it with a cable bridle. d) Connect the wiring to the terminal block of the sensor according to the chapters “Connecting the transmitter to the controllers”. When using the second ex . ,,e” bushing, drill a hole with a diameter of max 16 mm. Only certified Ex “e” bushings with the M20x1,5 thread are allowed. While drilling make sure to not damage the transmitter electronics. e) Assemble the transmitter with the four 4 mm hexagon sockets screws.

2. Replacement of the sensor module This activity must not be performed when the sensor is energized.

In case of need to replace the sensor module with a new piece, unscrew and remove the cover. On the sensor module, unscrew a pair of 3mm hexagon socket screws and remove the sensor module using a tool to prise it from the inside. Carefully insert a new module – the pins may not be bent. Secure with a pair of screws and slide the cover on the device, then secure it.

3. Replacement of the battery
The battery lifetime in the sensor is approximately 5 years. After this time Panasonic BR2032 some functions of the detector may not work properly. Remove the battery
from the holder and replace it with one of the recommended types. Replacing the battery in a transmitter, which is not connected to the power, will erase the internal clock.

Connect one transmitter to each channel of the controller as shown in the picture below.

5. Connecting the sensor via RS485 to the controller DEGA UPA III/UDA III

6.

Installation of wiring for RS485 and power supply

Wiring must be installed using bus topology and in compliance with the RS485 policy.

The maximum number of connected transmitters per controller channel is 32 (may be less depending on the configuration of the controller), while the total length of the controller (electrical distance between the controller and the last transmitter) should not exceed 1200 meters. Because of the voltage drops caused by individual sensors,

7

the total sum of the distances between the individual transmitters, the total sum of the distances between the

individual sensors and the controller L1 + L2 + L3 + … + L16… can be maximally:

Cable type

NSx-CL II NSx-IL II NSx-EL II NSx-PL II PID

Shielded 4×0,8mm 2,1 km 2,9 km 4,2 km 2,1 km

Shielded 4x1mm 3,3 km 4,4 km 6,5 km 3,3 km

Shielded 4×1,5mm 6,2 km 7,3 km 11,6 km 6,2 km

Shielded 4×2,5mm 10,1 km 13,5 km 20,1 km 10,1 km

Selecting the appropriate type of cable depends on the fire report and the protocol for determining external influences.

7. Setting the RS485 address of the transmitter
Each transmitter must have a unique address within the entire bus, otherwise there will be communication collisions and malfunctions. The transmitter address can either be set internally using the DegaConfig program or using the DIP switch on the PCB. If the position 6 (labeled ADD) is in the ON position, then the address is set according to the setting of pins 1-5. Otherwise the address set in DegaConfig is accepted. The address can be set from in the range of 1-31 using binary values. A table with DIP switch settings for the individual addresses is provided in Attachment 1.

8. Termination resistor
According to the RS485 specifications, the last device on the bus must end with the termination resistor 120R. Plug a jumper on the JP2 connector of the last device on the bus to include the 120R terminating resistor. In the default configuration the jumper connector is not plugged.

9. Communication protocol switch DEGA/MODBUS
Plugging a jumper in the JP1 connector will switch from the DEGA communication protocol to the MODBUS communication protocol.

Transmitter functions
The detector’s motherboard is equipped by status LEDs, which help in detecting problems during the installation.
LED ,,POW” shines at correct power LED ,,TxD” flashes when transmitting a packet via RS485 LED ,,RxD” flashes when a packet is correctly received via RS485 LED ,,ERR” shines/flashes in case of malfunction or substandard situations
1. Turning on the transmitter After turning on the power the LED “POW” starts shining and the LED “ERR” starts flashing, indicating a forming sequence of the sensor and automatic testing procedures, which can take up to 180s depending on the sensor used. The output of the current loop is 1mA. During this sequence, testing of internal electronics and stabilization of the sensor in order to eliminate false alarms after turning on take place. After the completion of the formation, a 4mA current begins to flow on the output of the current loop and the transmitter starts working according to its settings.
2. Gas detection The transmitter continuously measures the detected gas concentration in the atmosphere and converts its current value into a 4-20 mA signal or transmits its value to the evaluation unit via DEGA/MOBUS protocol.

8

3. Malfunction If a malfunction of electronics or the sensor is detected during operation, the transmitters starts transmitting via a 0,5mA current loop. On the PCB this state is indicated by the yellow LED “ERR”.
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 “ERR” starts flashing. The connected sensor must be calibrated immediately. The transmitter will transmit the information about the ending calibration via current loop. The transmission will be as follows: 10s of transmitting a 4-20mA signal informing about the actual gas concentration followed by a 1 second interval of 2mA current.
5. Reading the record of measured concentrations and alarms The transmitter periodically stores the current detected concentration into its internal memory after 60s. The internal memory retains data from the last 64260 measurements (cca. 44 days). In order to read this information, the program DegaConfig is required. See the DegaConfig program instruction manual.
Operation, maintenance, inspection and service of the transmitter
1. Usage limits
To maintain proper operation of the transmitter, it is necessary to respect the fact that step changes of humidity, condensation or rapid changes of pressure can cause incorrect indication of the measured value. Each sensing technology is suited for different methods of application, as described below. All sensors are characterized by a smaller or larger crosssensitivity to other gases than those they are set for. Therefore we recommend that you have the air in the deployment area of the detection system analyzed before processing project documentation. a) catalytic 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. Long term crossing of the measuring range causes a decrease in sensitivity. In case of an atmosphere with oxygen content of less than 17 %, the measured value will be undervalued. In case of an atmosphere with oxygen content of more than 25 %, the measured value will be overvalued. b) electrochemical sensors: Constant exposure to toxic gases or short-term exposure to gases, which greatly exceed the maximum range of the sensor, can damage the electrochemical sensor, which requires recalibration or replacement. High temperature along with low relative humidity have a negative effect on the sensor’s lifetime. In case of an atmosphere with oxygen content of less than 1 % for longer than 1 hour, the measured value will be undervalued. c) infrared sensors: Acids and alkali vapors may etch the optical system and distort the measurements. A check or a calibration may be necessary. d) photoionization sensors: it is necessary to clean the UV lamp regularly, its clogging may cause loss of signal.
2. Operation To maintain proper operation of the transmitter it is necessary to respect the fact that the presence of certain concentrations of gases or vapors, other than those for which the sensor is set, can cause an alarm set off, even if the concentration of the gas does not exceed the set level. Given the range of disturbing gases or vapors (diluents, exhaust gases, vapors of organic substances, disinfectants, etc.) a generally allowable concentration of interfering gases can not be determined. Data on cross-sensitivity to certain gases are included at the respective sensors. Therefore we recommend to that you have the air in the deployment area of the detection system analyzed before processing project documentation.
3. Operation/Maintenance In case of contamination the surface can be cleaned with a slightly moistened cloth. The sensors have a different lifetime depending on the sensing technology used and environmental conditions. Characteristics of the sensors vary over time. Therefore it is required to perform regular checks and calibrations, which can be done in two ways:
9

a) 1x every six months carry out a ,,calibration” and functional control – adjust the sensitivity of the sensor using calibration gas and check the functionality of the system. The exact interval depends on the purity of the environment, required accuracy and the occurrence of disturbing gases in the atmosphere.
b) 1x every twelve months carry out a ,,calibration” – adjust the sensitivity of the sensor using calibration gas and check the functionality of the system. The exact interval depends on the purity of the environment, required accuracy and the occurrence of disturbing gases in the atmosphere. Also carry out a ,,functional control” 1 x every three months – checking the function of the entire detection system using a test gas, which does not exceed the range of the sensor. We recommend using gas intended for laboratory use.
Means for testing fire alarm detectors may not be used for the ,,functional control”! Perform calibration only at certified service centers with a valid certificate of competence or at the manufacturer. For the Czech Republic only DEGA CZ s.r.o.

General warranty terms and conditions
When following the instructions for installation, operation and maintenance, the manufacturer guarantees 24 months from the date of receipt for the product. Should the product purchased be put into operation by an entity other than the seller, the warranty period commences from the date that the product is put into operation, provided that the buyer ordered its commissioning within three weeks of its receipt. The customer expressly acknowledges that during the warranty period that extends beyond the length of the warranty period that is specified in the Commercial Code (the statutory warranty) s/he can neither require replacement of the product nor may s/he withdraw from the contract.
1. When claiming a product defect it is necessary to submit a proof of purchase of the item containing the following information: name and surname, name and business name of the seller, his identification number, in case of a legal person their name, identification number and registered office, in case of a physical person their name, surname, place of residence and warranty certificate, provided the buyer received one from the seller. The validity of the warranty shall not be affected by non-compliance with the obligations related to the issuance of the warranty card.
2. Claims concerning the product (for a warranty repair only complete devices are accepted) may be filed during the warranty period only with the seller from which it was purchased; subsequently the seller is required to forward the product to an authorized service centre or to the manufacturer.
3. A condition for the recognition of the rights under the warranty is the installation of the product having been undertaken by an authorized person in possession of a valid certificate from the manufacturer.
5. Claims regarding a product defect that can be dealt with reasonably quickly and without additional consequences will be resolved by remedying the defect (repair) or by replacement of the concerned product part, because in such a case replacing the entire product would contradict the standard norms (§ 616, paragraph 4 of the Commercial Code).
6. The buyer who exercises the right of warranty repair is not entitled to the return of the parts that have been replaced. 7. The warranty period can be extended for up to 48 months and its validity can be extended beyond the standard length on the basis of
the conclusion of an individual warranty contract. Further information may be obtained through a specific business meeting.

This warranty is not applicable to: · a transmitter that has not been put into operation by the manufacturer or by a certified employee in possession of a valid certificate
issued by the manufacturer · a product that did not have regularly performed calibrations and functional checks by the manufacturer or by a certified employee in
possession of a valid certificate issued by the manufacturer · damage caused by fire, water, static electricity, power surges in the electric supply or in the public network, accident, improper use of
the product, wear and tear · contamination of the product and its subsequent cleaning · damage caused by improper installation, any adjustment, modification or improper manner of use inconsistent with the instruction
manual, the technical standards or the applicable safety regulations in the Czech Republic · damage to the product during transportation caused by improper handling or handling of the product in a manner contrary to the
advice provided in the instruction manual · DEGA products that have been used in association with other than original DEGA products, including consumables and accessories · calibration of sensors, i.e. setting detection limits
· wear or damage of the transmitter sensors, including the necessity of their replacement · wear parts and consumables (such as the key for removing the sensor, seals, etc.), which are detrimental to normal wear and tear
during operation, together with wear and tear of the product and its parts caused by their normal use
