Page 6: Preliminary Information
Description of operation The Alpa EcoTerm XT Gas Detector is one of the elements of the gas detection system. It performs cyclical measurements of gas concentration in the air. Information about exceeding a certain threshold is transmitted using the controls located on the bottom side part of the housing (see figure 1) and output current signal. -

5 (lowest) Correct operation of the detector Warm-up Table 1: Priorities of the Alpa EcoTerm XT Gas Detector The type of gas, the thresholds and the corresponding current value for a specific detector should be checked in the calibration certificate. -
Page 8: Safety
www.atestgaz.pl 1.2.3 Alarm (threshold 3) This state occurs when the gas concentration exceeds the alarm threshold (3rd threshold). Actions to be taken: remove bystanders from the danger zone, as far as possible, allow the airing of the endangered rooms – by opening windows and doors (if the control unit does not automatically switch on the ventilation). - Page 9 www.atestgaz.pl Although switching power supply of the Gas Detection System off, there is a possibility that a dangerous voltage can exist on the terminals of the Control Unit. It can originate from another system like for an example ventilation system that uses one of the output pins of Control Unit.

www.atestgaz.pl Set-up 9.2.1 Location of detectors The location of detectors should be determined by the designer of the system, taking into consideration the following principles: methane detectors should be installed less than 30 cm below the topmost point of the facility roof. -
Page 18: Figure 7: Example Connection Of Cables To The Device
www.atestgaz.pl The detector should be mounted with the use of Ø6 rawl bolts or M5 screws using the mounting holes accessible after the housing is open, so that the gas inlet is directed downwards. The housing dimensions, mounting hole spacing and the arrangement of the elements are shown in the figure 1. -

In the last detector, set the configuration switch in position 2 (see Figure 6). -
Page 22: Start-Up
www.atestgaz.pl Start-up 9.3.1 Handover inspection After performing the power supply and signal installation of the detectors, it is necessary to check and start the installation. Checking is based on further addition of detectors (or their simulator – see below) to the installation and checking the reaction of the control unit. -

Page 29: 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 30: 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 31: 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 32: 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 33 L2 [m] Quantity of detectors L1 [m] L2 [m] Quantity of detectors Table 1: Maximum quantity of Alpa EcoTerm XT detectors – open loop configuration Atest-Gaz A.
