Loop detectors in recent years have become a popular tool having innumerable applications in policing, right from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of the loop detector.

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 : 11 levers adjustable 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 .

Loop Installation:

The loops are sealed using a “quick-set” black epoxy compound or hot bitumen mastic to blend with the
roadway surface.

If the detector is not working?

Press reset

If red led indicator is not fully lit? Check for power supply

 If green led indicator ?

Blinks slowly?  It maybe because the loop is short circuit or the no: of turns is not enough
 Blinks faster?  It maybe because the loop is open or the no: of turns is too many.

 If no: of turns is not enough?

Lower the frequency (if the frequency is still too high, you must add more turns).
 If no: of turns is too many? Higher the frequency (if the frequency is still too low, you must remove some turns).
