Remote Power Adapter
Wiring Guide
Model ORRPA
Connections and Installation Tips
1.Connect the RED wire to a constant (+) 12 volt source. This can be the memory wire for the head unit (check to see if the radio is code- protected before cutting or unplugging the memory wire) or the (+) 12 volt battery terminal of the amplifier.
2.Connect the BLACK wire to ground. The radio chassis or amplifier ground terminal are gener- ally good locations for this connection.
3.The BLUE wire should be connected to the am- plifiers or signal processors that are being con- trolled be the Remote Power Adapter. It supplies a (+) 12 volt output rated at 1 amp, with a one to three second delay when triggered by signal on the GRAY wire.
4.The GRAY wire may be connected to any wire from the head unit that measures above (+) 5 volts when the unit is on and below (+) 3 volts when the unit is shut off. This includes power antennas, amplifier remote outputs (typically
(+) 12 volts but may be as low as (+) 5 volts in some OEM systems), or speaker outputs. A high- powered deck will normally supply between (+)
5.The GREEN LED built into the ORRPA lights after the delay period, indicating that the remote output is triggered.
6.The trigger delay is controlled by input volt- age on the GRAY wire. A low voltage input will increase the delay to a maximum of three seconds, at (+) 12 volts the delay drops to about one second.
Note: If the adapter is being triggered by a speaker output, it will stay on (along with the devices it controls) for a short period after the head unit is switched off. This is due to the stored energy of a typical chip output and can- not be avoided. To prevent

8.The Remote Power Adapter will drive up to 1 amp of load at (+) 12 volts. If multiple devices to be switched exceed the 1 amp limit use a second adapter. For
