Model S-1200 Vehicle Detector

Two Channel, Shelf-Mount, Back-Lit LCD Display

The Model S-1200 Series consists of detectors designed to meet or exceed NEMA Standards TS 1-1989. The S-1200 detector is a two channel, shelf mount type loop detector with individual channel detect and loop fail indications provided via two high intensity red LEDs and an easy to read LCD screen. All detector settings and parameters are configured using a set of four pushbuttons and the LCD screen. The S-1200 offers advanced
features providing built-in diagnostic capabilities all of which are viewable by means of the LCD screen. These include: 1.) real-time loop frequency, 2.) loop inductance and -?L/L%, 3.) a bargraph indication of relative inductance change (which ensures proper selection of sensitivity level), 4.) a record of accumulated loop failures, and 5.) a timer countdown of programmed timing functions.
