Installation of 6 smoke detectors with radio module in an old house with cultivation and crooked buildings, partially great distances. Installation in accordance with the instructions enclosed with no problems possible (NOTE: Be sure both range tests perform). Installation was done with adhesive pads: keep very well. Signaling via all smoke detectors in a line ensures that you will be just in case actually alalrmiert if there is a fire at the other end of the house. Successful and professional product; but comes at a price.
