Would like to use two motion sensors (the ones sold individually and
not connected to any lights) to turn on three flood lights. The idea
would be if either motion sensor was tripped the three lights would go
on.

My thought was to connect the switched side of the one motion sensor
to the three lights and to the switched side of the other motion
sensor. So it would be:

(Hot Wire) Motion Sensor[A](Switched Wire)Light(Switched
Wire)Light(Switched Wire)Light(Switched Wire)Motion
Sensor[b](Hot Wire)

My concern is that the current applied to the motion sensor that is
NOT activated when the other is activated may damage the motion
sensor. In other words if Motion Sensor [A] is tripped it would allow
current to flow to all three lights and the switched side of Motion
Sensor [b]... would that damage Sensor [b]?

Thanks,

Wouldnt you blow the circuit if both trip, you will be feeding 120 to
itself.

This is why you must use the same feed to both motion detectors. In the
event that you used a leg of different potential, you'd blow the detector






X10 has remote units that can trigger many lights, when I
pull in the garage 4 sensors go off, with 15 lights, the garage sensor
triggers 3 more through a code that goes through the AC lines. one in
garage, two outside, one inside, and 3 button garage remote are
compatable. X10 also has battery powered RF sensors and interior
keypads and a computer program it sells. Cheap home automation.
