WARNING: The AirLink 9900 is a radio signal repeater used to increase the distance between
AirLink sensor assemblies and the receiving AirLink monitor. The AirLink 9900 does
not detect or display the detected gas levels in the environment.
A site survey is required in order to determine the best placement and quantity of
repeater assemblies that may be required. Improper installation can lead to
inconsistent communication between the AirLink sensor assembly and AirLink
monitor which could result in personal injury or loss of life.
