Induction 220 V Parking Control System Car Detector Sensor For Access Control System
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.
Operation and Indication
While the detector is tuning, the green Channel LED and red Power LED will be turn on. It remain about 2 seconds,
then the green LED turn off. If a loop fault exists the Channel LED will come on and flash indicating a fault. If the fault
is self-healing the detector will continue to operate. The green channel LED will also glow whenever a vehicle is
detected passing over the inductive loop. The red Power LED at the top of the unit will remain on to indicate that the
unit is powered.
Frequency
To eliminate interference of two neighbouring wire loops or loop detectors, the frequency can be altered.
Sensitivity
The sensitivity of the detector allows the detector to be selective as to the change of inductance necessary to produce
an output. There are four sensitivity selections and are set as follows by DIP3 and DIP4 Switch.
Control functions:
Parking control.
Vehicle counting.
Traffic analysis.
Traffic control.
Access control.

MAIN FUNCTION AND FEATURES
1) Reset Switch: The reset switch enables the detector to be manually reset during registering and testing and it
is a process of system recovery
2) Selectable Pulse Time: This feature sets the length of time that the pulse relay will be lasting 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 Reinforcement: This feature sets the un-detecting level to a maximum sensitivity to prevent failing
to detect vehicles as big trucks
5) Switch Sensibility Adjustable: 4 sensitivity setting are available on the switches to change sensitivity
6) Switch Frequency Adjustable: 4 frequency settings are available to prevent signal interference with neighboring
loops
7) Filtering Option: This option is used to provide a delay between detection of the vehicle and switching 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 ensures the detection of the vehicle will be maintained when the vehicle
stays within the loop area for extended periods
9) AC220V ,AC110V , DC12V ,DC24V available.
