Staff Answer
After the optimum location for the sensor is determined using the information in the Installation Overview, dig a hole approximately 10 - 12 inches deep and 24" long within 2 feet and parallel of the driveway. Place the sensor flat in the hole and parallel to the driveway.

answer 2
You have to dig a small hole for the magnet (about 12 inches by 6 inches). Then a small trench for the wire (maybe 3 feet long). Took me about 5 minutes to install.

answer 5
Yes, the sensor is buried next to the driveway and there needs to be a trench for the wire to the sending unit (transmitter). This gave me the ability to conceal the transmitter in the woodline. This served two purposes: hiding it, and keeping it out of the way of mowers and snow plows. It is very simple, but mine was tricky because I had to be careful of the buried "Invisible Fence" wire. In addition, this unit also senses ATVs going down the drive.

Staff Answer
This Mighty Mule wireless driveway alarm is compared to a door bell in volume and features an LED light for the hearing impaired.

It will beep twice after a driveway signal is received and the visit alert LED light will flash three times then remain lit.

The LED light can be reset after you have acknowledged someone is in your driveway.

Staff Answer
Yes, the sensor is usually buried 12" below the ground and the cold will not affect its performance. The transmitter will work best if it has a clear path and is not blocked. Putting the transmitter at least 18" from the ground is usually sufficient.
