The DCMA-2500 is a long range wireless driveway alarm system with a range of up to 2500 feet, or half a mile.
The DCMA-2500 is a kit featuring a PIR based transmitter, or sensor, which will pick up any kind of movement, and a receiver. Both of these products are very similar to their counterparts as featured in the Dakota Alert WMA-3000 set. The difference is their range. The WMA-3000 has a range of up to 650 feet while the DCMA-2500 kit has a range of 2500 feet.
The transmitter runs on a 9-volt battery (not included) and has a detection zone of about 50 feet. When the sensor detects movement, it sends a wireless signal back to the receiver.
The receiver plugs into a standard wall outlet and is powered by a 12Volt transformer. Other features on the receiver is a 5 minute exit delay which gives you time to delay sensor activation so it won't detect you leaving the house. The receiver also has four "c" relay outputs and one 12Volt DC output allowing you to tie in additional products to the receiver.
The receiver also has four distinct zone capability allowing you to tie additional sensor and associate a distinct zone to a sensor or variety of sensors.
You may purchase additional receivers, and sensors that are compatible.
