Certifications and Approvals Standards for your safety. Underwriters Laboratories (UL) is an independent organization in the USA that tests and certifies products with regard to their safety, with a focus on fire and personal protection. UL approval of MSR-Electronic products indicates demonstrated compliance with the safety regulations of the USA and Canada. The safety integrity level (SIL) is a term from the field of functional safety. The safety integrity le- vel is used to assess electrical/electronic/programmable electronic (E/E/PE) systems and refers to the reliability of safety functions. The aim of safety functions in industry is to protect the health of the people working there, the environment and goods. These safety functions are realized with the help of a safety circuit, which can consist of different operating devices such as sensors, actuators and control elements. The ATEX Product Directive 2014/34/EU for equipment and protective systems intended for use in potentially explosive atmospheres sets out the rules for placing products on the market that are used in potentially explosive atmospheres. MSR-Electronic certifies with this certification that the products meet the essential health and safety requirements for design and construction as well as the requirements regarding the measuring function in hazardous areas. International Electrotechnical Commission (IEC) is an international standards organization for standards in the field of electrical engineering and electronics. IECEX = IECEx stands for „International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres“ or „international procedure for certification of electrical equipment used in hazardous areas”. Similar to ATEX, IECEx has regu- lations that classify environments into specific hazard classes. A number of standards issued by the IEC are authoritative in this regard. ATEX applies in Europe and IECEx worldwide (except Europe or USA). CSA: A global leader in standards development and an internationally recognized and accredited provider of testing, inspection and certification services for the North American and global markets. MSR-Electronic products are tested in CSA‘s EMC laboratories. Approvals are issued by DEKRA Tes- ting and Certification GmbH. 14 Certificates

Garage, Tunnel, Loading Zones Protection against CO / NO2 / LPG Garages and tunnels above a certain size (re- gulations vary from region to region) require a gas warning system, at least with carbon mon- oxide monitoring. Here, the specifications of EN 50545-1 must be complied with; e.g. at which value the system triggers an alarm and which warning devices are used. Gas sensors, control- lers and warning devices from MSR-Electronic reliably protect people and equipment in these areas. In addition, the gas detection system can be precisely adapted to the respective regulation thanks to flexible setting options (e.g. switching thresholds differ depending on the federal state). ! GAS HAZARDS In the event that the permissible CO limit value of 30 ppm is exceeded, the legislator has reliably regulated safety-related requirements in EN 50545-1. Fixed gas detection systems are the crucial monitoring instrument of a ventilation system. It regulates the air quality in closed rooms and decides when the ventilation must be started. In the event of a risk of poisoning or fire caused by leaking LPG gas from motor vehicles, the rescue control center is informed at the same time. + BENEFITS • Different controller models for the management of small garages up to the management of 128 gas sensors for large garages (type Digital-Gas-Controller DGC-06) • Controller also suitable for control cabinet installation • Modular design, therefore easily expandable • Reduced costs due to easy maintenance, e.g. sensor head replacement (X-Change technology) • Easy replacement of old system, easy communication with BMS, GLT • Compliant with EN 50545-1 and EN 50271 22 PolyGard®

Refrigeration Systems Protection against refrigerants Refrigeration systems above a certain size must be equipped with a gas detection system. The re- quirements for gas detectors depend on the type of refrigerant and the specific application. Among other things, the requirements of EN 378 and EN 14624 apply here. Gas sensors from MSR-Elec- tronic are safer than the standards require and reliably protect life and system. Thanks to flexib- le setting options, the gas detection system from MSR-Electronic can be adapted precisely to the relevant regulations (e.g. switching thresholds). Depending on the number of sensors required, the large DGC-06 MSR controller or an MSC2 stand-alone controller is used. ! GAS HAZARDS In refrigeration systems, it is necessary to distinguish between natural refrigerant gases and synthetic refrigerants. Synthetic refrigerants can affect health and must therefore be monitored for leaks in the circuits. With the natural refrigerants such as propane, ammonia and CO2 there is on the one hand the danger of explosions in case of leakage and on the other hand also the danger of poisoning. In this case, it is particularly important to react to the properties of the respective gas by monitoring them appropriately with the help of sensors. + BENEFITS • DGC-06 controller for management of up to 128 sensors for various refrigerants • Compactcontroller for management of up to 10 sensors, completely operable via the display • MSC2 controller for management of up to 3 sensors in combination with the GC-06 or as a stand-alone device, has 3 potential-free relays • Easy and fast calibration of digital and analog sensors • Compliant with EN 50545, EN 50271 and EN 378 24 PolyGard®

Dispensing Systems Protection against CO2 poisoning and O2 deficiency Whether in restaurants, brewing and fermen- tation cellars, breweries, wineries, beverage bottling plants, or in CO2 extinguishing systems in warehouses and production halls, wherever CO2 cylinders, lines and tanks are required, the sensors from MSR-Electronic can be used. The DEM-06-IO-A module secures access to enclo- sed spaces where CO2 leaks may occur and in- dicates an increased gas concentration in real time. This ensures perfect safety. MSR-Electronic offers reliable sensors, controllers and warning devices for dispensing and cooling systems. ! GAS HAZARDS The danger of dispensing systems is often underestimated because CO2 is odorless and invisible. On the one hand, carbon dioxide itself is very toxic, and on the other hand, it displaces oxygen. Both dangers can be monitored by gas sensors. A combination of O2 displacement monitoring and CO2 concentration measurement is the safest way to operate the equipment without danger. + BENEFITS Integrated test and maintenance function • Safety product: more than all national standards require • LED display: warning against entering the room • • Plug & Play • Optionally also for multiple entrances: parallel warning for the respective door • Compliant with EN 378 26 PolyGard®

Laboratory and Medicine Detection of different gases When handling various hazardous substances in laboratories and medical facilities, relevant safety measures must be observed in accordan- ce with the Hazardous Substances Ordinance (GefStoffV) and the laboratory guideline. Relia- ble monitoring of the wide variety of gases in the ambient air must therefore be guaranteed. The Compactcontroller from MSR-Electronic is designed to connect up to 10 gas sensors via its own fieldbus and is used to warn of various gases. MSR-Electronic also provides reliable so- lutions for extended applications, e.g. for large capacity laboratories. ! GAS HAZARDS • When gases are released in laboratory recirculation stations, fume hoods and equipment for filtering of gases in research and university laboratories In the pharmaceutical industry: fermentation and clean room monitoring In medicine: cryopreservation, anatomy, forensics, pathology, histology and respiration In the chemical industry in the production of substances • • • + BENEFITS • Plug & Play • Display for indication, configuration and calibration functions (no additional tool required) • Automatic closing of magnetic gas valves in case of gas alarm • Fieldbus connection for up to 10 gas sensors (SB2 units) • Hardware and software according to SIL-compliant development process • Modular technology (pluggable and exchangeable), reverse polarity and overload protected • 3 relays, 2 transistor outputs, 2 digital inputs, different housing types with IP65 28 PolyGard®

Ripening Chambers Safety against CO2 / C2H4 / C2H4O and O2 deficiency In addition to the modern technology of the ri- pening chambers, gas sensors are required for permanent monitoring of the various gas con- centrations involved in the ripening process. The sensors, controllers and warning devices from MSR-Electronic effectively protect people and equipment and monitor the system as a central point of the entire process. With the help of mo- dern communication technology, it is possible to react quickly. The Compactcontroller is designed to connect up to 10 gas sensors via its own field- bus and is used to warn of different gases and is therefore ideal for the application. ! GAS HAZARDS Fresh fruits and vegetables are alive and continue to breathe after harvest. This leads to oxygen con- sumption and the generation of carbon dioxide and water vapor. Keeping the produce fresh means slowing down the process while maintaining the quality of the product. To speed up or slow down the ripening process, different CO2 and O2 concentrations are set, which are permanently monitored by a gas detection system. + BENEFITS • Display for indication, configuration and calibration functions (no additional tool required) • Fieldbus connection for up to 10 gas sensors (SB2Units) with max. 900 m length • Hardware and software according to SIL-compliant development process • Modular technology (pluggable and exchangeable), reverse polarity and overload protected • 3 relays, 2 transistor outputs, 2 digital inputs, different housing types with IP65 30 PolyGard®

Aquaculture Systems Safety from various gases and oxygen deficiency The advantage of fish farming in an aquaculture system (RAS or a specially designed tank) is that production is independent of location and has minimal impact on the environment and water consumption, as it is a closed system. Moreover, they can be built near consumer markets and in regions where there is not enough water or sui- table climatic conditions for selected fish spe- cies. Water treatment and sterilization play an essential role in aquaculture. This places great demands on the facilities as well as new health safety criteria for the personnel working there. ! GAS HAZARDS Farmed fish are sensitive to pathogens, water quality and toxic substances. High water quality and disinfection of facilities is provided by ozone oxidation or ozonation. Ozone is a health hazard and the- refore dangerous to employees working in ozone production premises. Gas sensors, controllers and warning devices from MSR-Electronic offer perfect protection in case of occurring ozone gas leaks. + BENEFITS • Continuous MAK monitoring of O3/O2 and other gases • Up to 3 measuring points per controller • Modular design, expandable up to 128 measuring points with the DGC-06 controller • Easy integration into existing safety systems • 3 relays, Modbus and analog measured value forwarding • Cost-reduced calibration by sensor head exchange on site (X-Change technology) 32 PolyGard®

Beverage Industry Safety from CO2 / SO2 / H2S / C2H60 / CH3OH and O2 deficiency In the beverage industry, the danger from gases is often underestimated. Soft drinks and beers are perceived as refreshing due to „carbon dioxi- de,“ and in still beverages carbon dioxide impro- ves shelf life. But carbon dioxide is also indispen- sable for wine and sparkling wine production. MSR-Electronic offers reliable gas sensors, con- trollers and warning devices to protect people and equipment from hazardous gases. When gas leaks occur, fast alarming and reliable gas detec- tion systems are required. The Compactcontrol- ler from MSR-Electronic is designed to connect up to 10 gas sensors via its own fieldbus and is used to warn of various gases. ! GAS HAZARDS In breweries, wineries, beverage bottling, dispensing and CO2 extinguishing systems for warehouses In carbonation of soft drinks and inerting of tanks or pipelines • • • Use of SO2 as a preservative and antioxidant • Odor problems caused by H2S in the food industry • Alcohol production: spirits production with toxic and flammable gases • Monitoring of O2 deficiency to protect people in enclosed spaces + BENEFITS • Plug & Play and with display for indication, configuration and calibration functions • Hardware and software according to SIL-compliant development process • Reduced costs due to easy maintenance, e.g. sensor head change (X-Change technology) • Intelligent sensors display information on residual sensitivity, maintenance and condition • Less downtime and integration into existing safety systems 34 PolyGard®

Vending Machines Safety in case of a refrigerant leakage The global market is moving away from clas- sic high global warming potential refrigerants (GWP) and the use of natural refrigerants is in- creasing. Due to the higher flammability of na- tural gases such as propane, installations must therefore be protected with gas detection sys- tems. MSR-Electronic offers the sensor SSAX1, which can be easily integrated into vending machines and reliably detects any gas leakage. MSR-Elec- tronic offers reliable sensors, controllers and warning devices for refrigerated vending ma- chines. ! GAS HAZARDS Gas leaks in vending machines are very dangerous because the natural refrigerants used here quickly produce an explosive gas mixture. In the event of a leak, a reliable and rapid response is necessary, otherwise vending machine users are at risk. + BENEFITS • Conforms to EN 378, ATEX and IECEx certificates for electrical explosion protection • SSAX1 can be used for Zone 1 and Zone 2 • Continuous monitoring, reverse polarity and overload protected • Sensor with long lifetime (infrared: > 5 years) • High accuracy, selectivity and reliability, low zero drift • Cost-reduced calibration due to sensor head change on site (X-Change technology) 36 PolyGard®

Sensor Heads SC2 and MC2 With X-Change technology MSR-Electronic develops individual gas sen- sors, e.g. for CO2, CO, CH4, CH2O, NH3, O2 or H2 and systems in which toxic or combustible gas concentrations can form. These are integrated into complex warning systems and are used, for example, in parking garages, biogas plants, refrigeration plants, petrochemical industrial plants, breweries and dispensing systems or in laboratories and medical applications as well as in hydrogen production and processing. In addition to the sensor element and the mea- suring amplifier, the SC2 and MC2 sensors inclu- de a μController for measured value processing. Thus, various data can be processed and utili- zed, such as the temperature for compensation of the measured value. In addition, calibration interval and errors are monitored and transmit- ted to the evaluation unit. Thanks to the X-Change technology, calibration can be performed by simply changing the sen- sor head or by using the integrated, convenient calibration routine directly at the system. The sensors are designed for connection to MSR- Electronic controllers and boards. 42 PolyGard®

Sensor Heads SC2 and MC2 Infrared exchange sensor for selective gas measurement For applications where durability and high pre- cision measurement are important. The IR mea- suring method with integrated temperature compensation ensures highest accuracy, selec- tivity and reliability. In the μController all data and measured values of the sensor element are stored fail-safe and are digitally transmitted via the local bus to the sensor board SB2 or mul- ti-sensor board MSB2 or to the MSC2 or WSB2. The sensor head automatically transmits infor- mation about the maintenance interval to the controller. + BENEFITS • Long life expectancy • Low maintenance costs • High accuracy, selectivity and reliability • Measuring value setting time t90 < 30 sec. • Gilded mirror surface • Low zero drift • Sensor with long service life and high durability • Running-in time until operation < 60 sec. AIR GAS Reference channel Measuring channel UM Dual detector 44 PolyGard®

Sensor Heads SC2 and MC2 With electrochemical sensor element for toxic gases and coolants These sensors are used to measure mainly toxic gases such as CO, NO, NO2 and function accor- ding to the electrochemical principle. This me- ans that there is an electrolyte in a cell. It reacts proportionally to the presence of gas with the formation of ions, which ultimately generates a current. This change then indicates the gas con- centration. This principle has a high sensitivity and a fast reaction time, which is especially inte- resting for toxic gases. + BENEFITS • High sensitivity • Linear measurement signal • Low cross-sensitivity • No energy is required • Fast response time • No poisoning by silicones Electrolyte AIR GAS 45

Sensor Heads SC2 and MC2 With pellistor sensor element for combustible gases and vapors Pellistors or catalytic sensors consist of an acti- ve and a passive pellistor. These form a Wheats- tone bridge circuit, which is operated with a heating current of approx. 450 ° C. When gas is present, the resistance on the active side chan- ges, which generates a current flow. This met- hod is particularly suitable for explosive gases, where high linearity and measuring accuracy is required. + BENEFITS • Linear signal • High measuring accuracy • Temperature range -30 °C to 50 °C AIR GAS 46 PolyGard® Reference heating coil Open heating coil

X-Change Technology Exchangeable sensor SC2 and MC2 Until now, the necessary calibration of the sen- sors was a complex procedure and dependent on an external certified company. This was very time-consuming and expensive. The sensors had to be opened, checked and calibrated with great care at the construction site. If an error was found, it was necessary to take the com- plete sensor with you and replace it afterwards. With the new X-Change technology this effort can be saved. The exchangeable sensor head can be replaced on site at any time. The trans- mitter therefore remains untouched. This saves time and costs. + TIME-SAVING AND INDEPENDENT RECALIBRATION • Significant time and cost savings • Simple exchange process • Delivery of recalibrated sensor heads • Increased safety for your system R e c a l i b r a t ed sensor hea d s and Partner S e n s or heads to b e r e c a Customer r a t e d l i b MSR VIDEO How-to: X-Change technology for the PolyGard® product series 48 PolyGard®

Biogas Plants Safety against CH4 / H2S / CO2 / O2 When operating biogas plants, personal pro- tection and plant safety are of crucial import- ance in addition to process optimization. With the gas detection products from MSR-Electro- nic you work preventively against dangers. Gas sensors, controllers and warning devices are used to measure combustible and toxic gases as well as oxygen. Leakages are thus localized at an early stage. ! GAS HAZARDS Methane can react explosively with air. This represents a high hazard potential for the operator of biogas plants. An explosive mixture exists when the concentration of methane in the air is between 4.4 and 16.5 % by volume. Monitoring in pump rooms can protect people from dangerous leaks. Con- tinuous measurement in the double diaphragm (biogas trapped air hood) ensures leak tightness and thus freedom from loss. + BENEFITS • SIL2-certified PolyXeta®2 sensor for ATEX zones 1 and 2 • Metrological testing of sensors and devices according to EN 60079-29-1 for combustible gases/ EN 50104 for oxygen • Cost-reduced calibration through sensor head exchange on site (X-Change technology) • Solution for individual requirements, easy mounting by means of mounting bracket • Easy connection to existing systems (analog, Modbus) • 2 potential-free relays, e.g. to control warning devices 92 PolyXeta®

Petrochemical Industry Safe protection against CH4 / C5H12 / C3H8 / H2S / O2 / CO / NH3 In the chemical and petrochemical industry, permanent monitoring of rooms and plants in which explosive or toxic atmospheres can form is required. Personal protection requires the monitoring of hazardous gases in accessible areas, on the one hand to prevent accidents, and on the other to comply with MAK values and thus guarantee the health and safety of employees. In addition, MSR-Electronic of- fers solutions for the protection of your plant against gas leakage and thus financial loss. Also, the MSR gas sensors can further optimi- ze process safety. MSR-Electronic offers safe monitoring of combustible and toxic gases in petrochemical plants. ! GAS HAZARDS Chemicals, gases, solids and many waste products are generated in the petrochemical industry. The substances can be organic or inorganic in nature. At the reactors, storage sites and pipelines, the greatest danger is from escaping gases or volatile substances. To contain these hazards, reliable gas sensors must be used. + BENEFITS • SIL2-certified PolyXeta® sensor for ATEX zones 1 and 2 • Metrological testing of sensors and devices according to EN 60079-29-1 for combustible gases/ EN 50104 for oxygen • Cost-reduced calibration through sensor head exchange on site (X-Change technology) • Preconfigured devices on request, easy integration into existing systems • Protected according to IP66, 2 potential-free relays per device • Modular design and individual configuration 94 PolyXeta®

H2 Gas Monitoring For research, production, logistics and mobility The use of hydrogen as an energy carrier of the future is manifold. In addition to its use in wel- ding or as a fuel for rockets, the focus is cur- rently mainly on the automotive sector. H2 is a very reactive gas, which makes constant mo- nitoring by a gas detection system throughout the entire life cycle essential. For successful gas monitoring, the SIL2-certified PolyXeta®2 sensor with X-Change technology is used. The permanent gas monitoring serves the primary explosion protection and thus also the plant safety. ! GAS HAZARDS Hydrogen is an excellent energy carrier, but it is also one of the most difficult substances to trans- port anywhere. The extreme danger of hydrogen leaks lies here in the oxyhydrogen explosion. During research work, on test rigs and during the production of the gas, leakages can occur at any time and cause catastrophic damage in the event of ignition. Warning systems must also be installed in hydro- gen production from ammonia and in filling stations to protect people and systems from this highly flammable gas. + BENEFITS • SIL2-certified PolyXeta® sensor for ATEX zones 1 and 2 • Metrological testing of sensors and devices according to EN 60079-29-1 for combustible gases/ EN 50104 for oxygen • Cost-reduced calibration through sensor head exchange on site (X-Change technology) • Solution for individual requirements, easy mounting by means of mounting bracket • Easy connection to existing systems (analog, Modbus) • 2 potential-free relays, e.g. to control warning devices 96 PolyXeta®

PolyXeta® Sensor Head SSAX1 The ATEX sensor head for remote applications The ATEX sensor for combustible and toxic gases. In addition to the high-quality sensor element and the measuring amplifier, the sensor head SSAX1 contains a μController for processing the measured values. All relevant data and measu- red values of the sensor element are stored in the μController in a fail-safe manner and are transmitted digitally via the local bus to the WSB2 or output as PWM signal (pulse width modulation). The calibration management is also integrated in the μController of the sensor head. Calibration can be carried out by simply changing the sensor head or by the integrated, convenient calibration routine directly at the system. The new SSAX1 makes it possible to place the ATEX-certified sensor head alone in the hazar- dous zone and to lead it with the associated ATEX cable out of the hazardous zone to a WSB2 or PX2 for evaluation of the sensor. The SX1 is connected directly to the PX2 and can therefore be used as a complete device in the Atex zone. + BENEFITS • ATEX and IECEx certificates for electrical explosion protection • SSAX1 for zone 1 (also applicable in zone 2): Version „Ex db“ with flameproof enclosure • Continuous monitoring of toxic and flammable gases and oxygen • Different measuring principles depending on customer requirements and application (infrared, electrochemical sensor, pellistor) • High accuracy, selectivity and reliability • Easy calibration • Reverse polarity protected • Overload protection • 5 m cable length 106 PolyXeta®

X-Change Technology The PolyXeta® exchangeable sensor SX1 and SSAX1 Until now, the necessary calibration of the sen- sors was a complex procedure and dependent on an external certified company. This involved a lot of time and money. The sensors had to be opened, checked and calibrated with great care at the construction site. If an error occur- red, it was necessary to take the complete sen- sor with you and replace it afterwards. With the new X-Change technology this effort can be sa- ved. The exchangeable head can be replaced on site at any time. The transmitter therefore remains untouched. This saves time and costs. + TIME-SAVING CALIBRATION OF THE GAS SENSORS • Significant time and cost savings • Easy change process • Delivery of newly calibrated sensor heads • Increasing the safety of your plant R e c a li b r a t ed sensor hea d s and partners S e n s or heads to b e c a l Customer a t e d r b i MSR VIDEO How-to: X-Change technology for the PolyXeta® product series. 108 PolyXeta®

Commissioning and Maintenance With an international partner network MSR-Electronic offers together with its certified partners commissioning, installation and main- tenance of fixed gas detection systems. As a manufacturer of gas detection equipment, MSR-Electronic has an international network of partners to be able to offer these services worldwide. The service offerings are developed in close cooperation with the service providers and coordinated jointly with the customer. In this way, customers receive a complete package with all the requested services from a single source. The configuration The basic setting of the controller is a decisive component during commissioning or maintenance of the gas detection systems on site. The controller is the heart of the gas detection system. The individual measured values and requirements of the customer are stored here. The maintenance During maintenance, the entire system is first visually inspected after the maintenance interval has expired. The preset configuration of the controller is tested for actuality and the gas sensors are recalibrated during maintenance. This ensures that correct values always reach the evaluation unit or the controller. 140 Appendix

141

The calibration During calibration, the gas sensors are recalibrated based on their natural deviation after the speci- fied interval. During this calibration, the zero point is set first, i.e. the sensor is gassed in its natural ambient air or with zero gas and calibrated to this value. The 2nd value to be calibrated should be between 30 % and 90 % of the measuring range of the sensor. This calibration is then performed with the gas to be measured. For example, a carbon mon- oxide (CO) sensor with a measuring range of 300 ppm is calibrated with a test gas between 90 ppm and 275 ppm. Furthermore, triggering devices such as warning signs, alarm horns or flashing lights are tested during maintenance. The switching contacts, operating display and fault message are also checked. If an emergency power supply is available, its functional activity is also verified. Afterwards, the system receives an inspection sticker and the completion of the maintenance is noted in the inspec- tion book. All test procedures as well as necessary, upcoming maintenance are documented in the maintenance protocol and the absence of defects is certified. For an existing gas detection system, it is absolutely necessary to observe the maintenance inter- vals. This helps to always obtain correct sensor values in the evaluation unit. It also ensures that the plant will function properly in the event of increased gas volumes and that people and equipment will be safe. 141
