DSP-22-2 Vehicle Detector
Click Image to Enlarge
The DSP-22-2 detector is designed to be a low power, direct replacement for the existing DoorKing Model 9409 & 9405 dual channel inductive loop vehicle detectors for the parking and access control industries. The DSP-22-2 loop detector plugs into the loop detector ports on the DoorKing operator control board.
The DSP-22-2 operates as two independent channels. The DSP-22-2 is a dual channel detector that uses advanced channel scanning technology to provide superior noise tolerance. The scanning technology allows for placement of loops closer together (when both loops are connected to the same detector) than ever possible with single channel detectors.
The DSP-22-2 always operates in the Fail-safe mode of operation.
