Product Description
Single Channel – Dual Output Plug-In Vehicle Detector
Model NP2-ES Features:
- Plug-in compatible with many of today’s gate operators.
- 4 selectable Sensitivities.
- 4 selectable Frequencies.
- Wrong voltage protection.
- Separate Power/Fault and Detect Indicators.
- Automatic Sensitivity Boost.
- Power Supply requirement 10 to 30 Volts AC or DC, 5mA nominal.
The NP2-ES has been specifically designed and engineered for use in the Parking/Access Control industries and is designed for plug-in compatibility with many contemporary gate operator designs. With standard operations including compatibility with all radio controls and more, the NP2-ES covers your low power, plug-in detection needs.
The NP2-ES’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/fault and detect output provide for quick visual verification of proper operation. Loop diagnostics are easily viewed with the front panel power/fault indicator.
Reliable operation and long field life are key engineering goals in every Northstar
product.
Front Panel Selections:
Sensitivity – controlled by front panel DIP switch.
• 0 = Low sensitivity
• 3 = High sensitivity
Medium sensitivity is used for most applications; this is a setting of 1 or 2. 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.
Internal Switch Settings:
Call Delay – select from delay off and 2 second delay
Call Extend – select from extend off and 5 second extend
Permanent Presence – select from 60 minute and permanent presence.
Outputs:
Detect Output is fail secure, loss of power does not cause a detect output to be placed.
Factory Settings:
• Set to High frequency
• Set to Medium Low sensitivity (1)
Specifications:
Output Rating: Solid State both Detect and Fail. 30mA Maximum current sink. Outputs are protected from over-voltage or polarity reversal.
Power: 10 to 30 volts AC or DC, 5mA nominal.
Inductance Range: 20uH to 1500uH.
Temperature Range: -30 F to +180 F.
Lead-In Length: up to 2500 ft. with proper lead-in and loop.
Mechanical: 2.4” H x 2.25” D x 0.8” W.
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.
Indicators – front panel indicators:
Power/Fault – Green, solid with correct power supplied.
Flashes during a fault condition.
Fault flash sequence: Single flash and pause = Open Circuit Loop, Double flash and pause = Shorted Loop.
Detect – Red, solid during detect.
Power Saving Mode: While in normal operation with no fault indication, the Green LED will extinguish after a period of 2 minutes. A power interruption or reset will re-illuminate theGreen LED.
Sensitivity Boost – automatic during detect except in the
highest sensitivity setting (3).
Connector: – 10 position Molex Type 09-48-1104
