Safety Technology Intl. (STI)'s Wireless Battery or Solar Driveway Monitor with Single Channel Slave Receiver (STI-34159 or STI-34119) is designed to work in conjunction with a control panel. Sensor detects when a vehicle enters or leaves a protected driveway. It is ideal for home or office and uses a patented magnetometer sensor system. Movement of any large metallic (iron or steel) object close to the driveway sensor triggers a signal from the transmitter to the control panel. People, animals and shadows will not trigger the driveway sensor.
The small sized Single Channel Slave Receiver easily fits into control panel and operates up to 1000 feet (line of sight). Form “C” contact enables the device to interconnect with another system. Includes a Form “C” relay, 12 VDC operation, which can be momentary or latching. More Info: www.sti-usa.com.
