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.

Technical parameters of Loop Detector

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 .
