Key Features of JUTAI Industrial Detector for Access Control

• Industrial Durability: Made with weather-resistant materials, the JUTAI detector handles outdoor use in all seasons—no rust, no performance drops in rain or snow.
• Accurate Vehicle Sensing: Detects metal vehicles only (ignores bicycles, pedestrians, or debris), so your security gates only open for authorized traffic.
• Easy Wiring: Follows JUTAI’s standard loop connections (CH1: Pin 3,4; CH2: Pin 5,6) and relay contacts, so electricians can install it quickly without extra training.
• Sensitivity Tuning: 8-level DIP switch lets you adjust for small motorcycles or large delivery trucks, ensuring the JUTAI detector works for all your property’s vehicle types.

Installation Precautions and Troubleshooting:

1. Coil Cutting Size and Embedding Guidelines are as shown in the diagram on the right.
2. It is recommended to use ferromagnetic wires for the induction coil, with a total length of up to 500 meters.
3. The cutting size of the coil should be a rectangle with a length of 1.0 to 2.0 meters and a width of 0.8 to 1.2 meters, avoiding right angles at corners as much as possible.
4. Recommended installation overview of basic typical coil turns:

When installation, please keep the product plug and socket in the vertical direction

Application

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 the JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model: BR-110), and JUTAI long-range RFID reader (Model: PUHF-9), along with high-temperature resistance loop coils (Model: JTHT-11), it forms a seamless solution for single-channel entry/exit access control systems.

The working principle is as follows:

1. Entry Process:

   • When a car enters the community or parking lot, the two loop coils are pressed simultaneously.
   • The JUTAI Double Channel Loop Detector (LD-200/202) triggers the UHF reader located at the entrance.
   • The UHF reader reads the card ID and sends it to the controller (AC-11) via Wiegand output.
   • The controller verifies the ID's validity and outputs a relay signal to open the gate barrier.
   • The car enters the community or parking lot, and as it passes the barrier gate, the barrier arm lowers automatically.
   • The JUTAI Single Channel Loop Detector (LD-100/102) ensures safety and anti-smashing functionality during this process.

2. Exit Process:

   • When a car exits the community or parking lot, it passes by an inside UHF reader.
   • The LD-200/LD-202 triggers the UHF reader, which reads the card and sends the ID to the controller.
   • The controller verifies the ID's validity and outputs a relay signal to open the gate barrier for the car to exit.
   • As the car passes through the barrier gate, the barrier arm lowers automatically.
   • The LD-100/102 provides safety and anti-smashing functionality during this process.

3. Direction Recognition:

   • The Direction Recognition Function of LD-200/LD-202 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 Double Channel Loop Detector can also function as two independent single-channel loop detectors. This configuration is suitable for standard one-in and one-out parking lots, where there is one barrier and one long-range reader at both the entrance and exit.

In this setup, one loop coil is used to trigger the reader and read the card, while the other loop coil is dedicated to the barrier's anti-smashing function. By utilizing the LD-200/202 as two independent loop detectors, there is a potential cost-saving benefit from an economic standpoint. This setup reduces some of the hardware costs associated with using separate detectors for each function.

This functionality is achieved by enabling the Independent Working Mode feature of the LD-200/202, allowing it to operate effectively in this dual capacity.
