The LD200 series are dual channel inductive loop detectors. The use of the microprocessor based technology enables a large number of functions to be incorporated into a small package. The LD200 series is easy to set-up and install.
Typical applications include 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-turning the sensing loops and becoming ready for vehicle detection.
- Switch selectable Sensitivity.
- Eight sensitivity settings are available on the switches to allow flexibility in configuration.

Pulse Relay Selection.
The detect relay may be configured for a pulse output and to energize on detection of a vehicle or when the vehicle leaves the loop.
Selectable N/O or N/C output.
Internal jumpers enable the output relay contacts to be configured for normally open or normally closed contacts.
Direction Logic.
This feature enables the detector to give a pulse output on relay 1 for a vehicle traveling from loop 1 to loop 2, and a pulse output on relay 2 for a vehicle traveling from loop 2 to loop 1.
