Thanks to the built-in temperature compensation, detectors can work in changing environmental conditions. Information about the installed sensor module together with the alarm threshold values can be found on the detector housing. Table 1: Selection of ASG-2000 detectors.

Page 6: Functional Description
The default setting is to connect the common relay contacts to the V1 contact. The signalling diodes are marked in Figure 1. The ASG-2001 and ASG-2002 detectors on the sensor module include a cover with an anti-dust filter that protects not only against dust but also against small insects. In the ASG- 2003 detector, the sensor is insulated directly to the ventilation element. -

Page 8: Mounting Position
IK-E366-001 6.2. Mounting position. Detectors of the ASG-2000 series are recommended to be installed in a vertical position with the gas inlet down, this position guarantees the best protection against dust and splashes of water. In the case of methane detectors, due to the mounting height, a horizontal position (increased susceptibility to dust accumulation in the gas inlet element) or ceiling mounting is possible although not recommended. - Page 9 (applies only to detectors ASG-2001 and ASG-2002). Lack of the sensor cover reduces the protection of the housing to IP43, and detector operation without the sensor cover is not allowed. For ASG-2003 detectors, check whether the sensor insulation has been damaged.

Page 11: Testing Detectors
ASG-2003 containing 100 ÷ 200 ppm CO for a time suitable for triggering alarm A1 or A3, • for ASG-2001 and ASG-2002 containing> 20% LEL of gas detected until the alarm is triggered. When detecting a small amount of gas, the POWER diode is permanently lit with short stops every 2.5 seconds, allowing the test to be performed in a shorter time and not subjecting the sensors to a significant concentration of gas. -
Page 12: Storage And Transport
IK-E366-001 9.2. Work at heights. Work at heights related to the installation of detectors should be carried out with extreme caution when using efficient equipment and tools. Special attention should be paid to the stability of ladders, lifts, etc. Power tools should be used with observance of the conditions of their safe operation specified in the relevant manufacturer's instructions.
