This adapter is designed for use with the 1Byone Driveway Patrol Alert Alarm System. The DC input port is located on the top right side of the receiver. If you do not want to use 3 x 1.5V type C batteries for the receiver, just connect this AC power adapter.
Do not use batteries and the AC adapter at the same time to avoid battery leakage and combustion. Please remove the batteries before connecting the adapter to the DC port.
