Description
NorthStar Loop Detectors - NP2-C Single Channel Dual Output Plug-In Vehicle Detector

Model NP2-C (71-416-XNH) Features:
8 selectable Sensitivities.
4 selectable Frequencies.
Wrong voltage protection.
Separate Power/Fault and Detect Indicators.
Automatic Sensitivity Boost.
Power Supply requirement 24VAC or 120VAC, 1VA.

The NorthStar Loop Detectors - NP2-C Vehicle Detector has been specifically designed and engineered for use in the Parking/Access Control industries. With standard operations including compatibility with all radio controls and more, the NorthStar Loop Detectors - NP2-C Vehicle Detector covers your plug-in detection needs.

The NorthStar Loop Detectors - NP2-C Vehicle Detector 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).

A single Bi-Color LED will show power/fault and detect to provide for quick visual verification of proper operation.

Reliable operation and long field life are key engineering goals in every Northstar product.

NP2-C Specifications

Front Panel Selections

Sensitivity controlled by 8 position rotary switch.

0 = Low sensitivity (Least sensitive).

4 = Medium.

7 = High (Most sensitive).

Medium sensitivity is used for most applications; this is a setting of 3 or 4. Always use the lowest sensitivity setting that detects the desired vehicles.

Frequency four separate settings controlled by 2 board mounted DIP switches.

2+1 = High.

2+0 = Medium High.

1+0 = Medium Low.

0+0 = Low.

Reset changing the sensitivity setting will reset detector.

Switch Settings:

Switches 1 & 2 Provide 4 frequency settings

Switches 3 & 4 Provide 4 mode settings: OFF/OFF =pulse-on-entry, ON/OFF = pulse-on-leaving, OFF/ON = presence, ON/ON = fault

Switches 5 & 6 Provide for 4 different Presence lengths. OFF/OFF = 8 minutes, ON/OFF = 16 minutes, OFF/ON = 60 minutes, ON/ON = Permanent

Switch 7 Not used

Switch 8 Provides for Fail-safe or Fail-secure operation: OFF = Fail-safe, ON = Fail-secure (for power only).

Outputs:

Most applications require using the fail-safe relay #1 providing presence (detector stays in detect as long as vehicle is present over the loop up to the presence time limit). Relay #1 Normally Open connections are : Pins 4 & 5, the Green (common) and Violet (N.O.) wires from the wiring harness.

For a second output (pulse or presence) relay #2 is used. Commonly the #2 (Orange, N.O.) and #1 (Blue, common) are used, this will provide a Fail-secure for power output. When using relay #2 select the proper DIP switch settings for your application.

Detect Output in fail secure: loss of power does not cause a detect output to be placed upon power-up.

Factory Settings

Output Rating: 5A, 277VAC, 24VDC Outputs are protected from over-voltage or polarity reversal.

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.

7NH = 24V DC

3NH = 120V AC

Inductance Range: 20uH to 1500uH.

Temperature Range: -30 F to +180 F.

Lead-In Length: up to 1000 ft. with proper lead-in and loop.

Mechanical: 4.5 L x 3.250 W x 1.0 H.

Indicators

 - front panel Bi-Color indicator:

  - Power

    - Green, solid with correct power supplied.

  - Detect

    - Red, solid during current detect.

Fast Blinking Red during a current fault condition. Slow blinking red indicates a previous fault. This will continue until detector is reset.

Sensitivity Boost automatic during detect except in the highest sensitivity setting (3).
