Wall Power Adapter - Battery Eliminator for Driveway Patrol Alarms
Hard to find accessory for the Driveway Patrol Alarm system.  This wall plug eliminates the need for the uncommon "C" cell batteries normally required to run the Driveway Patrol Receiver unit.  Simply plug this into any A/C wall outlet and insert the cord plug into the socket on the side of the Driveway Patrol.  On a standard duplex outlet, the adapter does not cover the other outlet so you can still use that at the same time.  A red LED light on the power supply tells you it is working.  Now you can forget about whether your Driveway Patrol needs new batteries.
