VEHICLE DETECTION SYSTEM
The NP2 has been specifically designed and engineered for use in the parking access control industry. Standard operations include; programmable pulse and presence option, fail-safe or fail-secure operation, compatibility with all radio controls, timing features and more. The NP2 covers all your detection needs.  

Vehicle Loop Detectors use a coil of wire buried in the driveway which is connected to the inductive loop detector. The coil of wire (detector loop) is usually installed in a rectangular slot cut into the driveway surface at the time of installation. Pre-formed loops are sometimes precast into the driveway. The type of vehicle being detected determines the size of the detector loop. A 2-1/2' x 6' loop is typical for the detection of passenger cars and pickups.

When a detector loop cannot be installed in the driveway surface, and outdoor PIR (Passive Infrared Detector), microwave sensor, or photocell can be used.

The NP2's wide inductance range allows for use with small loops sometimes found in the parking market. Separate indicators for power on, detect relay 1, detect relay 2, and fault provide for quick visual verification of proper operation. Loop diagnostics are easily viewed with the front panel fault indicator, differentiating between current and historical faults thus facilitating troubleshooting. The small size and a full list of features lend the NP2 to any vehicle detection use from simple presence detection to configured pulse/presence lengths with output extensions and/or delays.
