Loop Detector for Parking Lot Access Control & Barrier Gates

• Power LED (RED): Illuminates to indicate "Power ON"
• CH1 Detection LED:
  • Steady On: Vehicle detection
  • Slow Blinking: Loop short circuit or insufficient twists
  • Fast Blinking: Loop open circuit or excessive twists
• CH2 Detection LED:
  • Steady On: Vehicle detection
  • Slow Blinking: Loop short circuit or insufficient twists
  • Fast Blinking: Loop open circuit or excessive twists

Sensitivity and frequency adjustment is facilitated through 7-way and 10-way dip switch settings. Users can choose from 8 different sensitivity settings by configuring the dip switch positions according to the provided tables.

Dip switches 6, 7, and 8 govern CH1 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive). Dip switches 3, 4, and 5 control CH2 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).

Switch 1 (S1): Channel 1 Loop Function Selection (10-way dip switch)

DIP 1 & DIP 2: Special Sensitivity Increase For Both Trailer (Both Channels)

D3, D4, D5 and D1, D2 Setting: Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode, two loop detection are separated)

D6 & D7 & D8 and D3 & D4 & D5 Setting: CH1 and CH2 Sensitivity Selection (Eight Levels Choices)

D9 & D10 and D6, D7 Setting: Frequency (20 K to 100 KHz)

• Coil cutting size should be a rectangle with length of 1.0 to 2.0 meters and width of 0.8 to 1.2 meters
• Avoid right angles at corners as much as possible
• Recommended to use ferromagnetic wires for the induction coil, with total length up to 500 meters
• Keep product plug and socket in the vertical direction during installation

The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for numerous single-channel entry and exit scenarios. When integrated with JUTAI door controllers, gate barriers, and long-range RFID readers, it forms a seamless solution for single-channel entry/exit access control systems.

• When a car enters, the two loop coils are pressed simultaneously
• The loop detector triggers the UHF reader at the entrance
• The UHF reader reads the card ID and sends it to the controller via Wiegand output
• The controller verifies ID validity and outputs relay signal to open the gate barrier
• The car enters and the barrier arm lowers automatically
• Single channel loop detector ensures safety and anti-smashing functionality

• When a car exits, it passes by an inside UHF reader
• The loop detector triggers the UHF reader to read the card and send ID to controller
• Controller verifies ID validity and outputs relay signal to open gate barrier
• Barrier arm lowers automatically as car passes through
• Single channel loop detector provides safety and anti-smashing functionality

The Direction Recognition Function ensures that the double channels loop detector does not trigger the signal again when the car passes another UHF reader, thereby recording only the entry or exit records in the system.

The JUTAI LD-200/202 can also function as two independent single-channel loop detectors, suitable for standard one-in and one-out parking lots. This configuration provides cost-saving benefits by reducing hardware costs associated with using separate detectors for each function.
