## Questions & Answers

**Q: Does this sensor work with the Chamberlain base, model CWA2000?**
A: Yes it does. I have 2x CWA2000 base units and 3 of these sensors. the 2 base units are at opposite ends of my house, and I have tuned all three sensors to both base units. All work just fine. You have to be very careful to mount the sensors where direct sunlight will not shine on them, also that there no windblown trees or any other object that will move substantially, is in the catchment range of the sensors. Remember that these sensors have quite a long range and a broad catchment area. I have mounted mine 4 feet above the ground and get no false alarms from stray animals (a frequent problem if not mounted high enough) or from moving shrubs, trees etc. Although I have had to prune back some shrubs to achieve this.

**Q: Is there an online manual?  I want to reprogram my beeps and I want to know why my base unit is giving me a low battery warning beep.**
A: Janet, the number of beeps indicates the order the devices were added. If you want to change which device beeps what number of times, the memory would need to be cleared and the devices added in the desired order. To clear the memory, hold the learn button on the base station until you get three beeps. Hope that helps

**Q: Dimension of sensor itself? Is the product dimensions in the description accurate? 3.8 x 5.6 x 3.1 inches.**
A: Yes, those dimensions are about right.  I think the 5.6" dim must include the "roof" that clips on to protect sensor from rain.  The sensor housing (as shown in picture) is less than 4" wide.

**Q: Does the add-on sensor include the mounting hardware, ie swivel mount with screws?**
A: Yes all the Necessary hardware was included. System works very well, I have four sensors send to the receiver, each with its own specific alert.
