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.
