Diablo Controls DSP-22-1 Loop Detector – Plug-In / DK Compatible – Single Channel

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.

The DSP-22-1 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-22-1 has a new unique flicker display that helps insure correct operation of channel 1 when it is operating in the pulse mode. The channel 1 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 1 of the DSP-22-1 can be connected to a standard inductive loop or the Diablo Controls Mini-Loop Probe. The Mini-Loop 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 Mini-Loop Probes can be wired in series to gain detection area. Contact Diablo Controls for more information on the Mini-Loop Probe. The Mini-Loop Probe can only operate in a pulse mode and therefore can never be used as a safety or obstruction sensor.
