Diablo DSP-22-2 Loop Detector

Diablo DSP-22-2 Loop Detector

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.

The DSP-22-2 continually monitors the loop circuit looking for conditions that would signify a fault in the loop circuit and displays the type of fault identified. This helps quickly identify open or shorted loops. Fault memory alerts the user to past faults that have automatically been recovered.

The DSP-22-2 has a new unique flicker display that helps insure correct operation of channel 2 when it is operating in the pulse mode. The channel 2 detect LED will turn on while the pulse is being outputted; then the LED display will go into a unique flicker mode while the channel is still detecting the vehicle. This allows easy identification of a locked-up channel operating in the pulse mode.

Channel 2 of the DSP-22-2 can be connected to a standard inductive loop or the Diablo Controls Free exit probe. The Free exit probe is a small round device approximately 4-1/2” long by 1” in diameter utilizing a 2-wire direct burial rated cable. It is designed to be buried in the center (optimum) or side of roadway to detect vehicles. Two free exit probes can be wired in series to gain detection area. Contact Diablo Controls for more information on the Free exit probe. The Free exit probe can only operate in a pulse mode and therefore can never be used as a safety or obstruction sensor.

Either channel can be disabled for flexible operating modes.
