The NP2 has been specifically designed and engineered for use in the Parking/Access
Control industries.
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
product.
