It is known where thieves can=20 drive down a road, and transmit a whole lot of codes to see if a door=20 opens, then come back another time an steal. The thought has come to=20 mind, that the wires could be an antenna, and as the power came up or=20 down, a random RF signal was emitted that triggered all these devices,=20 seems very remote, and well beyond my brain's ability to comprehend, but=20 we have had this setup for years and never seem it before. :) My=20 thinking at this point, has anyone else seen this phenomenon or have any=20 thoughts. :) On 2/21/2011 10:26 AM, Isaac Marino Bavaresco wrote: > Em 21/2/2011 11:45, Carl Denk escreveu: > =20 >> No, that's not normal, for the opener to open on power up, we have had >> many outages, or even if I unplug the opener when servicing (for >> safety), and plug it back in, there is no action.
