Essential Info

Too many people leave their garage doors open, only to discover others have helped themselves to your favorite tools. This Garage Sentry Sensor sends a signal to your Solar Wireless Driveway Monitor, Battery-Powered Driveway Monitor, or 8-Channel Receiver to let you know whenever your garage door is open. Simple installation; just screw the sensor to the bottom of your garage door, then "teach" your receiver to recognize it. Powered by a long-life CR-123A 3v lithium battery (included).

    The garage sensor is the exact same device as the universal sensor. They repackage it in a larger box and have slightly different instructions. But the same device. As with the Universal sensor you have to cut wire jumpers inside the unit to get it to function as a tilt, wired magnetic or wireless magnetic sensor. So if you cut the wrong wire you will have to solder the wires back together. They were obviously too cheap to build them with proper DIPP switches as a quality manufacturer would.
