Before you begin

Install remote sensor within the range of effective data transfer, as close to basic block as possible. Locate basic and remote sensors at places where the interference is minimal to provide the best data transmission. Take into account that data transfer range of remote sensor depends upon constructional material of partition walls and their number in the room. Try several variants of installation. In spite of the fact that remote sensor is protected against negative weather it is required to install it thus to avoid exposure to direct sun radiation, rain or snow. Household appliances (doorbell, signaling, etc) may create interference while receiving signal from sensor by the main block. This is normal, and this doesn't influence on the general performance of the appliances. Signal receives and data transfer would be resumed immediately after temporary interference is over.
