Wireless driveway alarms, like the Di2000S-A, will keep you informed and safe by alerting you when a car, person or animal enters your driveway or any area you would like to monitor. The system works by sending an alert when the passive infrared motion sensor detector is triggered.
The Di2000S-A uses a state of the art passive-infrared (PIR) sensor to detect any movement within the detection zone. When the sensor detects motion it transmits a wireless signal up to 1,000 ft. away to a plug-in receiver. When the receiver receives the alert, it emits a chime sound in order to notify you of any movement.
The sensor/transmitter sends out an invisible beam that is approximately 2” x 2” at one foot away from sensor to approximately 2′ x 2′ feet at 40 feet away from sensor. Essentially, the beam sends out a conical shape for a detection zone. If anything with a heat signature moves within this detection zone, the transmitter is triggered and will send a signal to the receiver, making it chime. The sensor is powered by 2 “AA” batteries (not included) and mounts with the supplied mounting bracket and mounting screws. Inside the transmitter are dip switches which allows you to pair it with other transmitters and receivers, and to determine the chime sound the receiver will play when triggered.
The receiver supplied in the kit plugs into a standard wall outlet. The front of the receiver features a counter that allows you to track the number of entrances through the detection zone. On the back of the receiver is a volume control knob that allows you to adjust the volume according to your preference. Also on the back of the receiver/speaker are two terminal screws; one is to power an external speaker, allowing you to hear the chime sound in another room or location. The second terminal screw is for a live 12 volt output, which can be used to power a variety of accessories such as strobe lights, sirens, counters, X10 interfaces, and virtually any product powered by 12 volts.
