    www.atestgaz.pl Closed alarm loop This system is different from the previous one in terms of connection of the end of the supply and signal line back to the control unit of the loop equipped with a test output (e.g. Alpa MOD LED1 Control Unit). In this way, it is possible to improve the power supply conditions of the sensor and resistance to damage.

    YTKSY, OMY, LiYY type (bus). For connecting the Alpa EcoWent XT detector, it is necessary to apply a four-wire conductor. The selection of a specific cable type depends on the designer and should take into account the conditions in the place in which the gas detection system operates.
  • Page 17 www.atestgaz.pl When selecting the cable, it is necessary to pay attention to voltage drops on the lines. The power line should be designed in such a way that, at the lowest expected voltage of the line power supply, the voltage "seen" on the detector terminals does not drop below the permissible value (see Section 10).

The control unit should show the state of OPERATION for the whole bus. Perform the test of the entire assembled bus. For this purpose, force the alarm on the last detector by pressing the TEST button in the detector.

  • Page 21: Periodical Operations

    9.4.1 Calibration During the operation of the system with Alpa EcoWent XT gas detectors, it is necessary to conduct periodic, systematic inspections of operation. The gas detector applied in the device is an element vulnerable to aging and environmental impacts, the natural effect of which is the decrease in its sensibility.
  • Page 22 www.atestgaz.pl The costs of calibration and travel should be incurred by the user. It is prohibited to test the sensor individually by applying a small amount of gas with an unknown composition and concentration on it, e.g. from a lighter. Such an operation leads to the poisoning of the sensor and the detector de-calibration.
