How it Works
A mercury switch inside the sensor senses whether the garage door is up or down. Anytime the door changes state, the sensor sends a radio signal to the receiver to update the position change. The green light glows anytime the garage door is closed and the red light flashes anytime the garage door is open. the receiver beeps each time the garage door is opened or closed.
One receiver can monitor up to 4 garage doors. When any monitored garage door is open, the red light will flash.
Sensor uses one 2032 type lithium battery (included) - Average battery life: One Year
Receiver uses 120V AC input/12V DC output adapter (included)
