Even if a vehicle arrives when the unit is without power, when power is restored the TRIAD system will show detect if there is now a vehicle in the detection zone. DSP-13 User Manual Page 3 of 16...
Indefinite, depending on environmental noise conditions. Detection Range: The type of vehicle will determine the actual point of detection. Larger vehicles will be sensed further away. The following chart is based on an SUV. DSP-13 User Manual Page 4 of 16 DSP13_MAN_B...

It should be noted that a power failure will always result in a fail-secure operation. Fail-safe operation is only available when a valid input voltage is applied to the detector. When configured for pulse output, the detector will always operate in the fail-secure mode. DSP-13 User Manual Page 7 of 16 DSP13_MAN_B...
1700 milliseconds and then repeat the sequence until power is cycled or the detector is reset. NORMAL The LED is always on when the detector is in its normal state of operation with no prior failure in memory. DSP-13 User Manual Page 8 of 16 DSP13_MAN_B...

A look at the following figure will show how this occupancy indication is used to provide additional information during pulse mode operation. In the figure the occupancy display is shown as the gray shaded area. DSP-13 User Manual Page 9 of 16 DSP13_MAN_B...
For 100 to 200 feet, use at least 18AWG wires. At greater than 200 feet, use a 16AWG wires at a minimum. Installation Practices: The sensors can be installed in several different ways depending on the type of driving surface and if the site is new construction or existing.

If the sensor cable needs to be spliced to another cable to get to the detector, the splice should be done in a junction box and the connections should be soldered and weatherproofed. DSP-13 User Manual Page 12 of 16 DSP13_MAN_B...
When configured for pulse mode the output will always operate in the fail-secure mode. OFF = the fail-safe mode of operation is selected. ON = the fail-secure mode of operation is selected. DSP-13 User Manual Page 13 of 16 DSP13_MAN_B...
LED, then the issue is with the sensor or its wiring. If the correct voltage is applied and the power LED is still flashing, replace the detector. DSP-13 User Manual Page 14 of 16...
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-13 User Manual Page 15 of 16...
If the sensitivity is set to 9 and the red LED still does not come on, swap the detector between a working detector and the detector with the issue. If the problem follows the sensor, the sensor is the problem. If it stays in the detector, replace the detector. DSP-13 User Manual Page 16 of 16 DSP13_MAN_B...
