The DCR-2500 is the standard receiver for our 2500 Series products. It has four form “C” relay outputs and one 12VDC output. The output durations are adjustable up to 10 minutes. The receiver will play one of four different tunes that are selected at the transmitter so that different zones can be distinguished. The receiver is powered by a 12VDC transformer. It also offers a 5 minute exit delay so you can leave the house without disturbing any occupants as well as a reminder beep and counter function.
