Type C: Reversing Polarity - Clifford Arrow 5 Installation Manual

type C: reversing polarity

Interfacing with a reversing polarity system requires either two relays or one DEI
451M (not included). It is critical to identify the proper wires and locate the master
switch to interface the door locks properly. Locate wires that show voltage on lock and
unlock. Cut one of the suspected wires and check operation of the locks from both
switches. If one switch loses operation in both directions and the other switch operates
in one direction only, you have located one of the target wires. The switch that lost all
operation is the master switch. If one switch works in both directions and the other
switch works in only one direction, you have a Type A system. If both switches still
operate, but one or more doors has stopped responding entirely, you have cut a motor
lead. Reconnect it and continue to test for another wire. Once both wires have been
located and the master switch has been identified, cut both wires and interface as
shown in the following diagram.

directly to (-) ground, possibly damaging the alarm or the factory switch.
