Introduction
The PD17x Series Single Channel Inductive Loop Vehicle Detector is a single channel microprocessor based detector,
designed specifically for parking and vehicle access control applications. It is suited primarily for access control
applications. Using the most up-to-date technology, the PD17x has been designed to meet the requirements of a vast
number of parking applications pertaining to operating conditions and various options available to the user.
The primary function of the detector is to detect vehicle presence by means of an inductance change, caused by the
vehicle passing over a wire loop buried under the road surface.

The detector has been designed for ease of installation and convenience, with automatic frequency selection to assist
with installation, as well as customisable outputs and operating modes, the product is easily configurable to suit various
applications. The unit provides diagnostic information by means of the Nortech DU100 and DU700
units.
The PD17x provides visual outputs (LED’s) on the front of the enclosure to provide an indication of the state of the
channel, as well as the detector itself. The channel LEDs indicate whether a vehicle is present over the loop or if there
is a fault on the loop. The power LED indicates that the unit is active and is also used to provide a means of
communication with the DU100 and DU700 units.
The unit has relay change-over contacts on the connector block, at the rear of the enclosure, for providing outputs as
configured by the front panel DIP switches.
