At last a plug-in detector which will operate on any voltage from 10 to 30 Volts AC or DC. The Diablo DSP-40S detector is covered by United States patent number US 7,132,959 Non-Interfering Vehicle Detection . These loop detectors are virtually cross-talk free in most applications. This loop detector has been specifically designed to handle parking, drive through and access control applications where solid-state outputs are required for both the Detect and the Fail outputs. The sensitivity level may be changed. (See below)
Loop Size - Works on any in-ground inductive loop from 20 to 1500 µH.
Indicators - Separate Power/Fail and Detect LEDs.
Detect Memory - Power interruptions of short duration are ignored. If power fails for approximately 1 . 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 pushbutton. 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
Power - 10 to 30 Volts AC or DC (20 mA max).
Loop Failure - The green power indicator flashes slowly if the loop circuit is open and quickly if the loop circuit is shorted. This detector will output a Detect for either of these loop failed conditions.
Outputs - Solid-state (open transistor collectors) for both Detect and Fail outputs. 30 mA maximum current sink - transient voltage protected.
Connector - 10 position Molex Type 09-48-1104 Mates with many female PCB 0.156 pitch headers in use by some access control devices and gate operators.
