Parking Lots Inductive Loop Vehicle Detector Alarm For Auto Gate Control
Introduction:
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 undetecting 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
