Are you ready for the EN 50545-1?

The EN 50545-1 is Europe’s response to the demand for more safety in tunnels und garages.
Effective from August 2014 the mandatory standard defines the standard of the detection and gas warning technology as well as the measurement in target systems and is further interpreted from country to country. Nevertheless, the standard is still not fully implemented by many manufacturers.
What is the EN 50545 in detail?

The target gases of the standard are those that are important for the safety in garages CO, NO und NO2. These are the result of combustion products in motor vehicles. Depending on the country there may also be additional gases. There are strict specifications for calibration accuracy with a maximum of 3 % deviation. The alarm systems must be triggered in a predetermined calculation and reaction time. The IP54 protection class for the sensors and the integration of an emergency power supply into the gas alarm system is required for the systems used.

The setting options of the alarm thresholds are now carried out according to international regulations, but also may be made stricter nationally. In addition there are exact longevity requirements. The definition of the software quality are made via the reference to the EN 50271. A SIL1 compliance is required here, but the FMEDA calculation is not mandatory. Narrow definitions of temperature, humidity and foreign gas influences require a high production standard for sensor and gas alarm systems manufacturers.

The catalog of specifications therefore includes narrowly defined production limits. It takes a large amount of technical effort in order to be able to confidently confront the standard. MSR-Electronic has overcome these obstacles through many years of experience in gas detection technology and had their products certified.

How do you get the certification?
In order to obtain a certification according to the new EN 50545-1, the producer needs to pass the extensive test catalog with different test definitions. To review the rules there is now a specification all over Europe for a uniform type examination. This controls whether you have EN 50545-1 certified products, the complete system complies with the standard and is designated for safe public use.
With its philosophy „Safety First“, MSR-Electronic stands for maximum safety
Therefore MSR-Electronic is also one of the few gas detection technology companies that already complies with EN 50545-1 and also meets the SIL2 requirements. This means that MSR-Electronic goes one important step further in its safety concept with its products and focuses on SIL2 (EN 50545-1: SIL1).
This means for the customers of MSR-Electronic that they need not be concerned about the safety of their gas alarm system. MSR-Electronic has already covered that.

In EN 50545-1 the responsibility stops at the signal evaluation. At MSR everything is covered from sensor to evaluation up to the actuators.
Consequently MSR-Electronic completes with its SIL2 complying products the closed loop and provides maximum safety systems.
The safety requirement level SIL (Safety Integrated Level) is a measure for the probability of failure of a functional system. It is indicated in levels from 1-4, whereby 1 represents the lowest level and level 3 is required only in most exceptional cases of gas detection technology.
Are your systems ready for the uniform type examinations in Europe?
On the subject of safety and innovations in garages and tunnels with EN 50545-1 and SIL by EN 50545-1 a symposium will be held in 2017.

Refrigerant Leak Detection in Supermarkets

For any supermarket, food retailing and air conditioning is associated with refrigeration. Behind the refrigerator and display cases that keeps the food at a desired low temperature; is a huge network that has refrigerant piping, valves, joints, compressors, condensers and many other such components. The leak of refrigerant gas from such commercial refrigeration systems is a major maintenance cost for super market chains. Gas leaks can also have a considerable effect on the environment. Hence, Refrigerant Leak Detection in Supermarkets is very crucial.

Over the past few years, large supermarket chains have become increasingly aware of refrigeration systems in their stores. This has happened for a number of reasons, most notably because refrigeration is one of the largest costs when setting up and running a store and there are a number of ways in which the associated systems can be optimized to save money. Now, with the added pressures placed upon those who operate commercial refrigeration systems by environmental legislation, the optimization of refrigeration systems is more important than ever.

As might be expected, the presence of refrigerant gas in large, complex mechanical refrigeration system inevitably leads to the occasional leak. Refrigerant is quite expensive and can have detrimental effects if leaked into the atmosphere. It is therefore imperative that leaks from refrigeration systems be minimised, both from financial and environmental points of view. By not having an appropriate Refrigerant Leak Detection in Supermarkets, you could be running your equipment inefficiently, risking breakdowns and unknowingly leaking expensive gases.

Gas Alarm Systems offers a complete system with sensors, controllers and warning device for for continuous monitoring of almost all types of refrigerants. Our sensors and controllers are easy to install and calibrate. The sensors detect the refrigerant gas in a particular range and depending upon the requirement can be configured for an analog or a digital output and triggers an alarm at a preset level. By recording the data around leak events, retailers can identify the problem areas. If such leak goes undetected it could degrade the refrigeration’s capacity to maintain proper cooling. Alarms are essentially warnings of such adverse conditions. Trained personnel can take action and call the appropriate store staff or maintenance personnel to avert situations where stock may be endangered.

Incorrect refrigerant handling can be very expensive through loss of energy efficiency, expensive refrigerant leakage and the risk of a catastrophic refrigerant leak. Installing Refrigerant Leak Detection in supermarkets  protects property and environment.

IECEx and SIL 2 Approved Gas Detection

Process industries such as Oil & gas, Petrochemical, Refinery and Chemical industries need special precautions to handle different hazardous substances that are used in the process or present in the atmosphere. For the protection of personnel and plant constant monitoring of toxic and combustible gases and vapours is required. The gas detection sensors for monitoring such hazardous gases needs to be installed and maintained in extreme harsh conditions.. Hence such products need to comply with general standards and regulations that guarantees the safety of the system.

At GasAlarm Systems, we provide innovative IECEx and SIL 2 Approved Gas Detection sensors to suit almost every industrial application where extreme environmental conditions prevail.

Basically there are three hazard categories in any process palnt:

• Combustible Gases: danger of explosion
• Toxic Gases: Danger of poisoning
• Oxygen: Danger of suffocation due to Oxygen deficiency or fire hazard due to excess Oxygen

Without technical aids human beings usually do not have the ability to recognize these dangers at an early stage in order to take preventive measures. GasAlarm systems therefore have a task of detecting hazards from toxic or combustible gases and vapors and to protect people, plants and the environment by means of appropriate measures.

Our PolyXeta II sensors with IECEx approval is an ideal solution for the gas detection in hazardous areas.

The sensors are classified into three main categories:

• Polyxeta II series Sensor with Ex demb[ib] Zone 1: For combustible and toxic gases, intrinsically safe, can be opened in Zone 1 without disconnecting
• Polyxeta II series Sensor with Zone 1: For comustible and toxic gases, with Zone 1 flameproof enclosure
• Polyxeta II series with Zone 2: For combustible and toxic gases, with Zone 2 flame-proof enclosure

The global importance of SIL has grown significantly over the last few years. GasAlarm System can now offer our PolyXeta II sensors with SIL 2 compliance.

In addition to compliance to legal and safety standards, PolyXeta II offers an ease of operation with its innovative design of change-element X-change sensor head.

Parking Guidance System for Smart Cities to enhances the attractiveness of India

Parking is critical for any business in shopping centres / Crowd Area. If you don’t have convenient parking, you don’t have customers as no one wants to drive around hunting for a single space among hundreds. Installing a parking guidance system – that would take a customer from the street all the way through to the individual available space; increases customers for a business and at the same time protects the environment.

ALVI -India in association with ALVI-Australia offers ultrasonic sensor which is placed above each parking space. This sensor indicates from a distance via an integrated LED, whether the parking space is free or occupied. While these sensors detect the single parking space, the ultrasonic counting sensors detect the outgoing cars. This data is then sent to the ParkGard control centre, which manages the number of free parking. Thus the individual sensors and signage that are connected to a central control system, gives parking management an extremely accurate counts of open spaces and where those spaces are and the visitors are easily headed to the nearest available parking space.

Very Early Fire & Smoke Detector, Gas Alarm offer one of the best smoke & fire detector which can be installed at any environment eg. coal mines, flour mills, pharma, clean rooms, oil & gas, etc. Early Fire detector / transmitter (VEFSA) is designed for detection of earliest sign of smoke & fire, and hence thereby offering better warning detection system, better than VESDA. Using unique detection technology and method, VEFSA offer best fire & smoke detection, without false alarm. These can be implemented at any location with quite easy. VEFSA is compatible for integration to any fire panel and alarm system, be to Siemens, Honeywell, GE etc. VEFSA works in environment and application where none of the conventional smoke & fire detection can work. VEFSA, though being more effective than some of the expensive solutions, it even more easy to implement and integrate, without having much design knowledge.

As VEFSA provide earliest signs of smoke & fire, it buy the critical time needed to investigate an alarm and initiate an appropriate response to prevent injury, property damage or business disruption. VEFSA offer various levels of integrity monitoring to ensure an alert is raised at any time, depending upon criticality of the application and environment. This is not the case with passive devices that are generally only electrically monitored with no ability to determine if smoke can actually reach the detection element. VEFSA offer dual level of alarms which are configurable. This VEFSA to provide very early warning of an event, prompting investigation at the earliest smouldering stage of a fire when it is easily addressed. Other alarm levels may be configured to provide fire alarm inputs to fire systems as well as releasing suppression systems. VEFSa alarm sensitivities are configurable and can be programmed to levels ranging from thousands of times more sensitive than a conventional detector, to much less sensitive.

VEFSA can be implemented across a wide (all) range of industries and applications, with no effect of dust, moisture, vibration, temperature, weather, pressure etc:

Industrial Gas Detection for Safe Protection in Hazardous Conditions

Most of the manufacturing industries  in the world, be it food & beverage production, mining or automotive, pharma industry, Oil & Gas, Refineries and Petroleum  industries  use processes that can produce dangerous levels of poisonous gases. Some gases are  easily recognized by  their pungent smell, but some are odourless and tasteless, making them particularly difficult to identify. All  around the world, a large number of people die every year as a result of inhaling toxic gases encountered in their various fields of operations and several explosions have occurred due to combustible gas leaks. Basically there are three hazard categories:

• Combustible Gases: Dangers of explosion
• Toxic Gases: Danger of poisoning
• Oxygen: Danger of suffocation due to Oxygen deficiency or fire hazard due to Excess Oxygen

Wherever such hazardous gases are stored, bottled, processed or transported, safety is at risk.

The dangers posed by such toxic and combustible gases are very significant hence there is a  need for gas detection  to keep the work-place and the workers safe.
