The DSP-22-1 detector is designed to be a low power, direct
replacement for the existing DoorKing Model 9410 single channel inductive loop vehicle detectors for the parking and access control industries. The DSP-22-1 loop detector plugs into the loop detector ports on the DoorKing operator control board.

The DSP-22-1 operates as a single channel detector. The DSP-22-1 is a detector that uses advanced channel scanning technology to provide superior noise tolerance.

The DSP-22-1 always operates in the Fail-safe mode of operation.
