Page 5: Preliminary Information
Preliminary information Purpose Gas detector Teta EcoTerm is designed as crucial components of the Teta Gas system for monitoring of hazardous gas concentrations and are dedicated to detect excessive (hazardous) concentrations of methane in public access facilities, in particular in underground garages and car parks, boilers or industrial halls. - Page 6 www.atestgaz.pl Depending on results of the foregoing actions the system may adopt various statuses that are described in subsequent paragraphs. 1.2.1 Operation It is the status when the gas detector is in sound working conditions and takes regular measurements. Measurement results for the monitored gas still remain below threshold limits and no irregularities in operation of the equipment are detected.

Page 7: Safety
www.atestgaz.pl Safety Do never install gas detectors at locations exposed to direct effect of water (moisture) or direct sunlight. When defects are revealed switch the detector off, secure connection cables and contact maintenance staff or a service team. Despite the power supply voltage for the Gas Safety System is off, dangerous voltage may persist across terminals of the Control Unit. -

Page 23: Detected Substances
www.atestgaz.pl Detected substances Detectors equipped with catalytic sensors are used for measuring and detecting the presence of gases and flammable gases in the range of up to 100% LEL. Principle of operation The catalytic sensor (figure 1) consists of two components: an active and a passive one, heated to a high temperature. -
Page 24: Impact Of Environmental Conditions
www.atestgaz.pl Impact of environmental conditions Never exceed the rated operating parameters of the detector. These parameters can be found in the detector calibration certificate. The detector must be used in accordance with the provisions in the User's Manual. Composition of the controlled atmosphere It is assumed that the standard composition of the atmosphere is a mixture of gases with the proportions indicated in table 1. -
Page 25: Effect Of Oxygen Concentration Value
www.atestgaz.pl concentrations over 100% LEL, even temporarily persistent ones, can lead to a physical wear of the sensor. For these reasons, detectors operating in places where such conditions may occur are / should be equipped with mechanisms to prevent the negative effects of high concentrations, a very high concentration of combustible gas (well above 100% LEL) leads to a decrease in oxygen concentration –... -
Page 26: Influence Of Vibrations, Impacts
www.atestgaz.pl Influence of vibrations, impacts Vibrations and impacts affect the detector's operation, as they may cause: damage to delicate parts of the sensor (e. g. detector element, compensation element), shift of the sensor's zero. It should be ensured that the detector is not exposed to shock and vibration in excess of the amplitude of vibrations amounting to 0.15 mm of the frequencies of over 10 Hz. - Page 27 www.atestgaz.pl Classification of chemicals used at Atest-Gaz Because of the need to present a consistent and high level of maintenance services, to ensure the safety of the calibration process and to create a basis for a rational calculation of the costs of this process, Atest-Gaz developed the "Classification of Chemical Substances"...
