CE Approved Parking Vehicle Access Control Loop Detector Model PD132
PRODUCT DESCRIPTION
Loop Detectors are used with vehicle detection loops to create an inductance from a magnetic field to sense
vehicular traffic and increase access control. Loop wire is buried underground beneath a road or driveway and
are connected to inductive loop vehicle detectors to detect the presence of a vehicle. They are most commonly
used under roadways to detect vehicles stopped at traffic lights.
Operating Guide
The detector must be installed in a convenient weatherproof location as close to the loop as possible.
WARING:
1) This unit must be earthed.
2) Installation and operation by service professional only.
3) Disconnect power before working on this unit.
A correct loop configuration and detector installation will ensure a successful inductive loop
detection system.

Main Features:
1) Reset Switch : The reset switch enables the detector to be manually reset during commissioning and testing.
This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection ;
2) Selectable Pulse Time : This feature sets the length of time that the pulse relay will be energized for 1 Second
or 0.5 Seconds ;
3) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a vehicle or when the
vehicle leaves the loop ;
4) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used to prevent loss of
detection of high-bed vehicles ;
5) Switch Selectable Sensibility : 4 sensitivity setting are available on the switches to allow flexibility in configuration ;
6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;
7) Filter Option : This option is used to provide a delay between detection of the vehicle and switchiing of the output
relay . This relay is normally used to prevent false detection of small or fast moving objects ;
8) Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is
parked over the loop for extended periods .
