NorthStar Loop Detector - NP2-120 Single Channel - Dual Relay Vehicle

      NorthStar Loop Detector - NP2-120 Single Channel - Dual Relay Vehicle Detector     NorthStar Loop Detector - NP2-120 Single Channel - Dual Relay Vehicle Detector  - 10 selectable Sensitivities.- 4 selectable Frequencies.- Wrong voltage protection.- Output Timing – Extend & Delay.- Selectable Presence times.- Selectable Pulse lengths.- Separate Power, Detect and Fault Indicators.- Automatic Sensitivity Boost.
The NorthStar Loop Detector - NP2-120 Single Channel 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 NorthStar Loop Detector - NP2-120 Single Channel 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 NorthStar Loop Detector - NP2-120 Single Channel 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.

NP2 Specifications

Rear Panel DIP Switch Selections

Relay 1

Extend – switch 1 is for extending the detector output after the vehicle has left the loop. Switch 1 in the OFF position provides no extension. Switch 1 in the ON position provides a 5 second extension once the vehicle leaves the loop. This extension applies to relay 1 only.

Delay – switch 2 is for providing a 2 second delay, detector will ignore the vehicle until the vehicle has been present over the loop for 2 seconds. Switch 2 in the OFF position provides no delay. Switch 2 in the ON position provides for the 2-second delay. This delay applies to relay 1 only.

Presence Time – switch 3 provides for either a 1 hour presence or permanent presence. Switch 3 in the OFF position provides for 1 hour of presence. Switch 3 in the ON position provides for permanent presence. The above presence settings apply to relay 1 only. (Other options are available).

Relay 2

Pulse Length – switch 4 provides for either a 250mS pulse length or a 500mS pulse length. Switch 4 in the OFF position provides a 250mS (standard) pulse length.

Switch 4 in the ON position provides a 500mS pulse length.

Operating Mode – switch 5 and switch 6 determine the operating mode for Relay 2. The four modes are as follows:

Switch 5 and switch 6 OFF provides pulse-on-entry.

Switch 5 ON & switch 6 OFF provides pulse-on-leaving.

Switch 5 OFF & switch 6 ON provides for presence.

Switch 5 and switch 6 ON provides a fault output.

Front Panel Selections

Sensitivity – controlled by front panel rotary switch.

- 0 = Low sensitivity

- 9 = High sensitivity

Medium sensitivity is used for most applications; this is a setting of 4 or 5. Always use the lowest sensitivity setting that detects the desired vehicles.

Frequency – four separate settings controlled by front panel.

DIP switches.

- 2+1 = High.

- 2+0 = Medium High.

- 1+0 = Medium Low.

- 0+0 = Low.

Reset – front panel reset performs a hard reset of the detector.
