Detector operates on any voltage from 10 to 30 volts AC or DC and draws approximately 35 milliamps of current with no vehicle on the loop.  This micro-sized detector has no user settings and will automatically configure itself when powered up.  When used with other DSP-6LPs, DSP-7LPs, or DSP-7s, the detector will not cross-talk. 

• Designed to be cross talk free between other similar loops detectors.
• Plug and play.  Switchless and self-adapting to most common installations.  Connect it up and watch it work.
• Small profile, perfect for many installations.
• Automatically compensates for loop and lead-In sizes
• Fail-safe operation.
• Wide low-voltage operation.
