The Driveway Alarm System is magnetometer based wireless driveway alert system which means it detects metallic objects only. Humans, animals, or other things non-metallic objects will not set the transmitter off. The transmitter or sensor, uses a 9-volt battery that is connected with 50 feet of wire to the probe buried in the ground. The sensor's probe should be buried parallel to the detection area (like a driveway) and will then detect cars within 10-12 feet. The When a vehicle drives by, the transmitter will send a signal to the WPA-3000 receiver up to 600 feet away. The Dakato Alert 3000 series is the latest technology from Dakota Alert and is not compatable with earlier products.
The plugin receiver in this set is the WR-3000 and plugs into a standard wall outlet and may be set to one of four tones. You may also add extra receivers and sensors to the 3000 series alarm sets.
Driveway Alert only detects cars! This driveway alarm is reliable, easy to install, and has up to a 600 ft range to receiver. The WPA-3000 by Dakota Alert is a solid performer ideal for situations where you ONLY want to detect large metallic objects in entering your driveway or street. The wireless sensor will not detect movement by non-metallic objects.
The WR-3000 is equipped with four form “C” relays (one for each channel), and one 12-volt DC output terminal that will activate for several seconds when a signal is received. The receiver can be user-programmed, so the 12-volt DC terminal and one relay will activate for 10 minutes, if this is desired. The tones will still sound for several seconds.
