Hello all,
Not sure how much activity is in this group so this is a test
posting. I have an electronic challenge and was wondering if there
was anyone in here that would like to brainstorm a bit to find a
resolve.
What I have is a exterior flood light motion detector head. When
the output is connected to the bulbs(resistance) the output is
zero(0). When not connected to the bulbs the output is 120vac. I
believe this because the motion is using a triac or similar device.
I need a way or component that will make the output a zero(0)vac and
upon activation will allow the output to goes HI at 120vac.
The reason is that I am trying to control the lights two different
ways. One thru a automation device and the other thru the motion
detector.
The automation device has a sensing input. In other words it just
needs a voltage input at 120vac to then turn on the output to the
lights. However because of the configuration of the motion detector
it needs to see the resistance of the bulbs to keep the output at
zero(0) voltage. Without this resistance value the output is
120vac. This 120vac voltage then triggers the input of the
automation module and turns on the lights and they will not turn
off.
What I think I am looking for is some sort of device that I can
install on the output of the motion detector to ground or neutral
that will make it think it sees the bulbs and put the voltage at
zero(0)vac. Then when the motion trips it will need to handle
120vac at 20 amps so that the voltage can go HI and can be seen by
the automation device.
Anyone know a proper device that can do this and be small enough to
fit into the electrical box behind the fixture??
Thanks in advance input.
