VEHICLE LOOP DETECTOR

The LD113 is a single channel inductive loop detector. The use of microprocessor based technology enables a large number of functions to be incorporated into a small package. The LD113 is of a single printed circuit board construction and is compatible with other similar single channel detectors on the market.

Typical applications in the parking and access control environments are safety loops, arming loops and entry or exit loops.

Standard features of the detector are :

· 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.

· Selectable Pulse Time.

This feature sets the length of time that the pulse relay will be energized for. 1 Sec or 0.2 Seconds.

· Pulse Relay Selection.

The Pulse relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop.

· Switch selectable Sensitivity.

Eight sensitivity settings are available on the switches to allow flexibility in configuration and application.

· Switch selectable Frequency.

Two frequency settings are available to prevent cross-talk between adjacent loops.

· Permanent Presence Option.

This feature ensures detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods.

· Filter Option.

This option is used to provide a delay between detection of the vehicle and switching of the output relay. This delay is normally used to prevent false detection of small or fast moving objects.

· Loop Fault Indicator.

This LED Indicator is illuminated when the loop is either open circuit or short circuit and is used to give a visual indication of a faulty loop.

· Selectable Extend Time.

This feature sets the length of time that the presence output will be extended for. Either 0 Seconds or 5 seconds.
