This additional transmitter is for use with the STI-34104 driveway alarm receiver. It uses a patented magnetometer sensor system. Movement of any large metallic (iron or steel) object close to the driveway sensor will cause the sensor to transmit to the receiver.
The sensor works up to 1000 feet (line of sight) away from the receiver in your home.
