Page 12: Alarm Levels / Changing Alarm Levels
Correct location of the detector is essential to ensure optimum operation of the system. Special consideration must be given to air movement and whether the gas to be detected is heavier or lighter than air. For gases heavier than air (e.g., Refrigerants (HFC, HCFC)) the sensor should ideally be located approximately 20cm above floor. -
