DSP-22S Series, Vehicle Detector

Overview

Another switchless single-channel vehicle detector product designed to work with the DoorKing operators.
Matches DKS® 9410-10 single channel or DKS® 9409-10 dual-channel detector.
® DKS is a registered trademark of DoorKing Systems.

This micro-sized detector will automatically adjust its sensitivity level when used on different sized loops. The detector loop inductance should be between 20 and 2000 microhenries.

This series of Diablo Controls detectors are covered by United States patent number 7,132,959 “Non-Interfering Vehicle Detection.”
Ordering Information

Automatically compensates for loop and lead-In sizes

Separate Power/Fail and Detect LED's for both channels

Small profile, perfect for many installations

Fail safe operation

Operates on 12 to 30 VDC

Available in single and dual channel models. Matches DKS® 9410-10 single channel or DKS® 9409-10 dual-channel detector. ® DKS is a registered trademark of DoorKing Systems.

LED Indicators: The green Power LED will be on steady to indicate the detector is operating and powered. The red Detect LED will turn on when a vehicle is over the loop detection area.

Detect Memory: Power interruptions of short duration are ignored. If power fails for approximately 1 ½ seconds or less the detector “remembers” a vehicle.

Sensitivity and Reset Push Button: The Reset/Sens. button is used for two functions. A short press and release of the button will reset the detector and the LED's will both flash from 1 to 4 times, indicating the detector's sensitivity level.
The detector is shipped from the factory with the sensitivity set at level 3. If a different sensitivity level is required push and continue to hold the button until the LED's start flashing; release the button immediately after the desired number of flashes.
For example, if the sensitivity is to be changed to level 2, push and hold the button until the LED's flash twice then immediately release the button. The sensitivity level can always be verified by a quick tap on the push button.
This will reset the detector and flash the two LED's indicating the present level.

Level 1 - Very Low
Level 2 - Low
Level 3 - Normal (Factory setting)
Level 4 - High

Loop or Wire Failures: In the case of a loop circuit failure, the green LED flashes slowly (twice per second) for an open loop circuit failure.
The green LED will flash fast (10 times per second) to indicate a shorted loop circuit.

Fail Safe vs Fail Secure: A fail safe detector will output “detect” when the loop circuit is failed. This is always useful on a safety loop.
On the free exit loop this will keep the gate open until the situation is fixed. This is useful in applications where it is important to allow traffic flow to continue.
A fail secure detector will never output detect when the loop circuit is failed. This will keep the gate closed. This is useful in high-security areas or installations where containment is needed.
The DSP-22S is a fail safe detector. Note: Never use a fail secure detector on a safety loop.

Channel 2 Pulse or Presence: The J4 jumper can be set to select presence or leading pulse on channel 2’s output relay. The factory default is for presence mode.

Outputs: Solid-state (open transistor collector) for Channel 1 detect and a SPDT 1 amp relay output for Channel 2.
