2. Introduction The DSP-10 Detector is intended to be a top of the line single channel detector. Many features have been included which are normally found only on more expensive models. The small package is powered by a high- performance 16-bit microcontroller that does not skimp on performance. The DSP-10 Detector was designed to retrofit into existing locations that may require a detector upgrade.

The B output is always fail-secure when not in the fail output mode. The DSP-10 is one of the few vehicle detectors that honors fail-safe and fail-secure even in the absence of power. Inside the unit, on the main PC board, are three jumpers that set the failure mode. When placed in the fail-safe position, the A output relay will be fail-safe in the absence of adequate voltage.
For those instances where a longer period is desired, extended presence will hold that same vehicle for about 19 or 20 hours. This is quite a long time, but it isn’t infinite. The DSP-10 does not have infinite presence.
Pulse on Exit: Every time the loop becomes vacant or a vehicle is tuned out, a single 250 milliseconds pulse will be output on the B output. Fail: If the DSP-10 recognizes some type of loop failure, a continuous output on the B output will be given. The B output will remain activated until the failure is corrected.
With this feature the detector may be able to detect the high-bed portion of the vehicle without having to be overly sensitive and susceptible to false detections. NOTE: If detection of high-bed tractor-trailers is required, correctly sized loops must be used. DSP-10 User Manual Page 11 of 26 DSP10_MAN_C...
The delay interval is fixed at 2 seconds. Indicators The DSP-10 is equipped with two LED indicators: Power (Green) and Detect (Red). Power LED – The green power LED indicates these possible states: The voltage applied to the detector is less than the minimum display voltage of approximately 7.75 volts.

50 milliseconds, on for 50 milliseconds, off for 50 milliseconds and then repeat the sequence until power is cycled or the detector reset. Normal The LED is always on when the detector is in its normal state of operation. DSP-10 User Manual Page 13 of 26 DSP10_MAN_C...
LED will return to the off state. If the vehicle is still present after 2 seconds, the LED will become solid and the A output will be activated. DSP-10 User Manual Page 14 of 26 DSP10_MAN_C...
Detect The LED will be on solid when a vehicle is being detected and the delay interval (if activated) has finished timing. Figure 8: Detect LED States DSP-10 User Manual Page 15 of 26 DSP10_MAN_C...
L = ( (6 + 14 + 6 + 14) / 4) x (2 + 2 L = (40 / 4) x (2 + 4) L = 10 x 6 Loop Inductance is approximately 60µH. DSP-10 User Manual Page 16 of 26 DSP10_MAN_C...
Location: The detector should be plugged in to the appropriate connector on the DoorKing operator. Mounting: The detector will function when mounted in any orientation. Using the two holes in the detector, secure the detector in place. DSP-10 User Manual Page 17 of 26 DSP10_MAN_C...
The number of turns to use in a loop is dependent on the size of the loop and length of the lead-in. Rather than dive into all of the calculations to arrive at a value, we will just give you a table of safe values based on the DSP-10 User Manual Page 18 of 26...

This will also help remove dust from the saw cutting operation from the sides of the saw slot. This will allow better adhesion of the loop sealant to the saw slot. DSP-10 User Manual Page 19 of 26...

Once the loop wire leaves the saw slot it should be twisted at least three times per foot. More is better. The twists should be kept tight to be most effective in reducing the effects of electrical interference. DSP-10 User Manual Page 21 of 26...

Swap the loops between a working detector and a failing detector. If the problem follows the loop the loop is the problem. If it stays in the same detector, replace the detector. DSP-10 User Manual Page 23 of 26 DSP10_MAN_C...
Another is that the loop wire has been damaged where it enters or exits a conduit or junction box, or that a conduit that the loop wire is in has been damaged (crushed, kinked, bent, cut, etc.). DSP-10 User Manual Page 24 of 26 DSP10_MAN_C...
Another possibility is metal objects in close proximity to the loop. Utility manhole covers are objects that may move slightly when vehicle tires drive over them, especially if the vehicle turns while a tire in on the cover. Most DSP-10 User Manual Page 25 of 26...
