Review: Muy buen sensor y recomendable
Review: The instructions are kind of badly organized so I'll just say here a few things some people might be confused about. First, both blue wires on the power pack are the same. This makes sense because all the power pack does is bridge them, so it doesn't matter which is line and which is load. Second, the ultrasound sensor can't turn on the load; they are for keeping it on after the infrared senses something. Finally, the sensor is very sensitive; I had it in a garage with the infrared sensitivity halfway up and it turned the lights on and I don't even know why. Maybe it saw some car pass by like 100 feet away through a frosted window. I settled on a sensitivity of about 40%. Ultrasound was up all the way.

## Questions & Answers

**Q: We have one of these in our office. When we're all at our desks working, the lights constantly shut-off. How do we keep the lights on for 8 hours?**
A: The timer can be set for 30 seconds to 30 minutes.  The detector may not be in range of the working area. Either relocate the detector or add another detector.

**Q: Can the osc20-m0w ceiling mount occupancy sensor be used to control 3 separate single phase 20 amp circuits and how can this be done?**
A: oh yea. you can use this sensor to energize a 3-pole lighting contactor or what we call a "definite purpose contactor" rated @ 20-30 amps with a 120 volt coil and run your circuits thru that and its just like one big switch. very simple. these contactors you can get for $25-30 open type and mount in small enclosure or deep junction box.

**Q: Candice sensor be set to dim the lights when vacant or will it only turn the lights completely off?**
A: The sensor will only turn the lights on or off.

**Q: How many of these can be daisy chained to cover a large office space?**
A: In order to save energy you may not want to cover large spaces. Having said that. I am not sure if these can be daisy chained, however you can parallel number of these through power packs.  The quantity that can be paralleled varies from manufacturer to manufacturer.
