Northstar NP2 has been specifically designed and engineered for use in the Parking/Access Control industries. With standard operations including programmable pulse and presence options, fail-safe or fail-secure operation, compatibility with all radio controls, timing features and more, the NP2 covers your detection needs.
The NP2’s wide inductance range allows for use with small loops sometimes found in the Parking/Access Control industries (for recommended loop sizes please consult the Northstar Loop Information Guide).
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.
Small size and full list of features lend the NP2 to any Parking/Access Control use from simple presence detection to configured pulse/presence lengths with output extensions and/or delays.
Reliable operation and long field life are key engineering goals in every Northstar

Supply Voltage – incorrect voltage supplied to the unit will
not result in damage, the unit will simply not operate until
correct voltage is supplied. No fuses need to be reset.

Power – Green, solid with correct power supplied
Relay 1 – Red, solid during detect
Relay 2 – Red, solid during detect
Fault – Yellow, solid during current fault, flashing for historical fault
Sensitivity Boost – automatic during detect except in the highest sensitivity setting (9).
