Product Profile
DSP-40S Vehicle Detector
All this and a 5-Year Warranty too!
At last a plug-in detector that will operate on any voltage from 10 to 30 volts AC or DC. The DSP-40S detector is covered by United States patent number US 7,132,959 “Non-Interfering Vehicle Detection.” This detector is virtually cross-talk free in most applications. It has been specifically designed to handle parking, drive-through and access control applications where solid-state outputs are required for both the detect and fail outputs. The sensitivity level may be changed. (See below). The detector loop inductance should be between 20 and 2000 microhenries.
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-40S is a fail safe detector. Note: Never use a fail secure detector on a safety loop.
