The NF102 is a series of single channel inductive loop detectors. The use of microprocessor based technology enables a large number of functions to be incorporated into a small package. Typical applications in the parking and access control environments are safety loops, arming loops and entry or exit loops.

STANDARD FEATURES:

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 Second 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.

Sensitivity Boost - This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles.

Switch selectable Sensibility - Eight sensitivity settings are available on the switches to allow flexibility in configuration.

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

Filter 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.

Permanent Presence Option - This feature ensures detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods
