DSP-40S Plug-in Vehicle Loop Detector (DIABLO CONTROLS)

The DSP-40S detector will add a new dimension of simplicity to your plug-in detector requirements. The DSP-40S has 4 levels of sensitivity which may be changed. At last a plug-in detector that will operate on any voltage from 10 to 30 volts AC or DC. 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 detector loop inductance should be between 20 and 2000 microhenries. The DSP-40S detector is covered by United States patent number US 7,132,959 “Non-Interfering Vehicle Detection”. Features Small profile, perfect for many installations Designed to be cross-talk free between other loops Works on any in-ground inductive loop from 20 to 2000 microhenries. Automatically compensates for loop and lead-in sizes Fail-safe operation Wide low-voltage operation Separate Power/Fail and Detect LEDs. This 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. 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
