Mighty Mule Wireless Driveway Alarm (FM231)

Instantly alerts you when someone pulls into or out of your driveway

The outdoor electromagnetic sensor only detects vehicles; no false alarms due to animals, children, etc.

Easy-to-install Electromagnetic Sensor Wand is buried next to your driveway, and detects mass metal moving within a 3-12 ft. radius of the wand.

When a vehicle passes by the sensor, an outdoor transmitter communicates wirelessly to an internal base station up to 400 ft. away and sounds a pleasant chime

Ideal for home and business

Requires 2 AA batteries (Sold Separately)

Low battery indicator on both the Indoor receiver and transmitter

Backed by a 12 Month Mighty Mule Warranty and Technical Support

The wireless driveway alarm alerts you when a vehicle enters or exits your property. When a vehicle passes the sensor, the indoor receiver emits a chime. It has a wireless range of 400' (121.9 m) and will not be activated by people, animals or wind. The indoor receiver can be mounted on a table or on the wall. Multiple indoor receivers (up to 3) can be added for more convenience. Detects moving vehicles; not a motion sensor.
