Page 5: General Information
General information Application field Gas detectors Teta EcoWent and Teta EcoN are designed as crucial components of the Teta Gas system for monitoring of hazardous gas concentrations and are dedicated to detect excessive (hazardous) concentrations of carbon oxide and nitrogen dioxide in public access facilities, in particular in underground garages and car parks. - Page 6 www.atestgaz.pl Operation of gas detector consists in periodical measurements of hazardous gases in their vicinity with continuous averaging of measurement results. Momentary concentration of gases are measured with the time period of 1 second and average concentrations are calculated. These measurements enable reporting of warnings or alarms.
-
Page 7: Safety
www.atestgaz.pl 1.2.4 Failure In parallel to measurements of gas concentration the detector carries out a series of self-test measurements to verify fault-free operation of the sensor and the gas monitoring system as a whole. The defects indicated by the gas detectors may include: problems with built-in gas sensors, error of communication with the control unit, incorrect configuration,... -

Page 11: System Architectures
System architectures The gas monitoring systems can be made up of independent gas detector Teta EcoWent or Teta EcoN or coupled and collaborating pairs of detectors (Teta EcoWent with Teta MiniDet). Data bus architecture In this system gas detectors are connected to the bus via T-connectors S2. -
Page 12: Mechanical Mounting Of Detectors
www.atestgaz.pl detectors must not be exposed to direct effect of water (moisture) or other chemicals (e.g. cleaning chemicals when the facilities are being cleaned), as well as to direct effect of sunlight, rain or wind, detectors must be secured against damaging mechanical impacts, locations of detectors must enable easy checks and adjustments as well as replacement or disconnection of each detector. -

Page 14: Configuration Of Gas Detectors
www.atestgaz.pl In case of improper operation of the system recheck all wiring and connections or contact the system provider /equipment manufacturer. The gas monitoring system can be approved for operation only after passing results of all aforementioned checks and verifications. Configuration of gas detectors Reliable operation of gas detector needs preliminary configuration of the device parameters. -

Page 16: Maintenance Schedule
www.atestgaz.pl Maintenance schedule Each user must be aware of the fact that operation of any gas monitoring system leads to inevitable ageing of equipment, in particular gas sensors, due to detrimental impact of environmental factors. Therefore the systems must undergo regular and scheduled maintenance. Maintenance operations shall include: calibration of gas detectors, replacements of fast-wearing parts,... - Page 17 – test gas is supplied to inlet of the gas detector (or a pair of coupled detectors), the message ‘tE’ should appear on the device display, simulation of alarms for CO concentration (for Teta EcoWent detectors) or NO (Teta EcoN detectors), the message ‘S1’...

Page 23: Detected Substances
www.atestgaz.pl Detected substances Detectors equipped with electrochemical sensors are used for measuring and detecting the presence of specific substances in gaseous atmospheres in concentrations generally above single "ppm," but in some cases (e.g. oxygen, hydrogen), the concentration may be tens or hundreds of thousands "ppm". These gases have characteristic measurement ranges. -

www.atestgaz.pl with electrochemical sensors are designed to measure and detect the short-term presence of certain gases in the atmosphere. Both the more sustained concentration with values falling within the range of measurement, and even instantaneous concentrations outside the measuring range lead to a rapid wear of the sensor. - 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"...
