    www.atestgaz.pl The calibration procedure for gas detectors furnished with the FL.C head must be carried out with consideration of the following constraints (detector with FL.C head parameters – see Table 9): minimum flow of reference gas, wind velocity nearby the detector – it is important to pay attention to the air movement at a location where the detector with the FL.C head is used –...

  • Page 10: Safety

    www.atestgaz.pl Safety Testing of the detector with a gas of unknown composition or excessive concentration is forbidden since it may lead to irreversible damage of the gas sensor. All activities related to connecting detectors, signalling devices and other system components must be carried out when the power supply voltage for the control unit is off. Despite the power supply for the Gas Safety System is off, dangerous voltage may persist across terminals of the control unit.

  • Page 19: Figure 14: Correct Mounting Of The Gas Detector

    www.atestgaz.pl Figure 14: Correct mounting of the gas detector The manufacturer recommends application of the Mounting Bracket WM8 (see Table 12) – since it enables easy calibration of gas detectors and protects their housings against damage. First the mounting bracket should be mounted to a support structure (wall) by means of two rawlplugs or M6 bolts.
