PD-232 Good Quality Car Parking dual channel loop detector:
Functions & 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
