Introduction
The DSP-19 is a compact vehicle detector that will operate on any voltage from 8 to 35 volts DC. The low voltage
range is ideal for solar applications. The DSP-19 can be connected to a standard inductive loop or one of Diablo
Controls mini-loops. The Diablo Controls mini-
loop is a small “pipe shaped” device approximately 4
-
1/2” by 1” and
is designed to be buried in the ground to detect vehicles. Contact Diablo Controls for more information on the
mini-loop. The DSP-19 can be used as either a safety loop or free exit loop detector. It also has the flexibility to be
either “fail
-
safe” or “fail
-
secure”. The DSP
-19 has a single solid-state FET output.
The DSP-19 has 10 selectable sensitivity settings and uses a 6-position DIP switch to configure the detector. This
includes the Diablo Controls mini-loop selection as well as sensitivity boost, extended presence and fail- safe/fail
secure operation. This makes the DSP-19 very flexible and versatile for those installations that need a little more
than a standard detector
