Diablo DSP-6LP Micro Vehicle Loop Detector 9-30 VAC/DC Low Current Draw The Diablo DSP-6LP vehicle detector is designed for solar powered gate applications. This loop detector will operate on any voltage from 10 to 30 Volts AC or DC and draws approximately 1 milliampere while waiting for a car. The power LED winks continuously once per second to indicate the detector is operating in the low power mode. The Diablo DSP-6LP detector beats all competition for reliability, simplicity, and “no car” current consumption. This series of Diablo Loop detectors are covered by United States patent number US 7,132,959 “Non-Interfering Vehicle Detection”. These detectors are virtually crosstalk free in most applications. Working on battery-powered and other parking and access control loop applications, the Diablo DSP-6LP is preset to the normal sensitivity level used in parking/access control applications, and tunes itself to the best operating frequency. This micro-sized detector will automatically adjust its sensitivity level when used on different sized loops. Environmental conditions are constantly compensated with the Diablo Control DSP-6LP HYPERTRACK software. Environmental conditions are constantly compensated with the DML-9LP’s HYPERTRACK software.
