Does anyone know if you can hear a relay actuating? If so, that's why it works a with 120V LED.

Relays work through electromechanical coils and you can certainly hear them actuate. Motion sensors work on changes in perceived temperature changes. The signal is then sent to a transducer which changes this energy to an impulse which signals the light to be switched on.

Yes, I have noticed with this (and the other z-wave switches that I've used) there is a small buzzing. With mine, it was faint - and could only be heard if you put your ear to it. It is there though.

LEDs don't make noise. If you hear something, better look for other troubles.

Andy - I connected my contactor to a Variac and measured the coil current. I measured the following: Pull-in current 145mA to 155mA. Sustaining current 60mA. Drop out current about 30 mA. The solenoid buzzed really badly if the available current was LESS than 145 mA at pull-in, which leads me to believe that your problem is the output driver on the motion sensor can't provide enough current to pull the contactor in. You can measure the sensor output current to the contactor coil by CAREFULLY connecting a multimeter, set to the 10 amps AC scale, in series with your coil drive circuit, and monitor the amount of current it's putting out while the contactor buzzes. Be careful, 120 volts. If your driver can't provide the current to drive the contactor, one way around this would be to use a second, smaller relay to pull in the bigger contactor. Typical "ice-cube" 120v coil relays just require ~ 10-20 mA to pull in. Then this small relay's contacts could activate the coil of the larger contactor. If your motion sensor is providing the proper current then the problem may be related to noise, but I'd check your driver circuit's current capability first. Greg Walz greenlite350@aol.com

It does not give me flashing problem. It connects to 120V through a transformer, which is included.

No and that is my issue with this switch now. It worked great with incandescent bulbs but when I switched the three (porch area) out to LED, it controls them but also randomly turns each of the three in the circuit on and off like some odd Halloween light show -- only happens when it is supposed to be off and nothing picking up from the remote sensor. I even tried mixing back one incandescent bulb in an attempt to trick the circuit but it did not work any better.It looks like it is pulsing power out here and there which the LEDs are sensitive enough and require so little current that it momentarily lights them up.Time to look for another product that supports the new lighting standard.

Yes, it's normal. It clicks when the bitrate changes. From the Schiit Bifrost FAQ page: Hey, this Bifrost I got clicks! What's up with that? It's just the muting relay, operating normally. We chose a relay rather than relying on the D/A chip's soft mute, since it's safer and less sonically invasive. You'll thank us when you accidentally send some Dolby Digital content down the line and your speakers don't explode because of full-scale noise on the output.

If I understand correctly: If you are using the motion sensor to control this relay, the motion sensor itself may not be giving the necessary voltage or output to operate it correctly. All I can add is to make sure you have the power leg and switch leg on properly. A multi-meter (reading volts) could help find your issue. Hope this helps.

My lights don't make any significant noise, perhaps it is the transformer you are using.

The amprobe RC -1205 relay switch it can be use in closet lights or other application the needs normally close relay . What r you trying to do ?

Yes, there is a very light clicking sound. Not a loud one that you might here from something like the Power Tail Switch, but a gentle one.If complete quiet is important, you might want to look into the solid-state version of this relay.

I'm not exactly sure that I understand what you are asking, but here's my best shot. Hope it helps! Short answer: No. Long answer: If I understand this correctly you have 12V LEDs and a 110V dimmer? This power supply regulates to a target voltage around 12V optimally independent of the input voltage. Simply put, if you put 110V or 90V to this it should still output 12V. There is a voltage adjustment on here that you could use as a dimmer that lets you adjust the regulated voltage from 10-18V. So if you don't need a remote dimmer adjustment and this is enough variance for you then it might still work. Hope that helped, and let me know if you have any other questions!

Yes. This unit attaches to any 120v light fixture. As long as your LED bulb works in the fixture, this will turn it on and off when motion is detected at night. As someone else mentioned, the bulb cannot be dimmed when connected to this motion detector.

This is normal operation. You will only hear it while the backlight is on. Lux Technical Support

I tried to use one of these on my 50 Watt LED flood light and it was strobing/pulsing. From what I hear these motion sensors need a certain amount of current (amp draw) to work properly. Which isn't a problem if you're using a halogen/incandescent or even compact fluorescent bulb. But since the LED lights use so little current it just strobes. If anyone knows how to get these to work well with an LED flood light I would love to know. Thanks

I have two of these connected to dimmable 12V LED tape lights. They have been really quiet for me.

Paula,I've tested this and though the power LED lights up, it will not convert the signal properly. You will need to find a separate part for that.
