It leverages fingerprint recognition technology to provide secure and efficient access control. Designed for high-traffic environments, the AC-5000 ensures quick and reliable authentication, making it ideal for applications such as office buildings, data centers, and restricted areas. Its robust design and versatile integration capabilities make it a preferred choice for modern security systems.

• Office and corporate access control
• Data center security
• Residential and commercial building entry systems
• Industrial facility access management
• Integration with time and attendance systems

The Biometrico AC-5000 features a terminal block for wiring connections. Below is the pin configuration:

1. Power Connection: Connect the 12V DC power supply to the 12V and GND pins. Ensure the power supply is stable and within the specified voltage range.
2. Communication Setup:
   • For TCP/IP communication, connect the device to a network using an Ethernet cable.
   • For RS-485 communication, connect the RS485+ and RS485- pins to the corresponding lines of the RS-485 network.
   • For Wiegand communication, connect the Wiegand D0 and Wiegand D1 pins to the Wiegand-compatible controller.
3. Relay Connection: Use the Relay NO, Relay COM, and Relay NC pins to control an external door lock or other devices.
4. Fingerprint Enrollment: Follow the device's user interface or software instructions to enroll fingerprints. Ensure fingers are clean and dry for accurate recognition.
5. Integration: Use the provided SDK or API to integrate the AC-5000 with your security or attendance management system.

• Power Supply: Use a regulated 12V DC power supply to avoid damage to the device.
• Environmental Conditions: Install the device in a location within the specified temperature and humidity range.
• Mounting: Ensure the device is securely mounted on a flat surface to prevent tampering or damage.
• Network Security: When using TCP/IP communication, configure firewalls and encryption to secure data transmission.
• Regular Maintenance: Clean the fingerprint sensor periodically with a soft, lint-free cloth to maintain accuracy.

The Biometrico AC-5000 can be connected to an Arduino UNO for basic relay control via the Wiegand interface. Below is an example code snippet:

#include <Wiegand.h> // Include a Wiegand library for Arduino

WIEGAND wg; // Create a Wiegand object

void setup() {
  Serial.begin(9600); // Initialize serial communication
  wg.begin(2, 3); // Set Wiegand D0 to pin 2 and D1 to pin 3
  pinMode(8, OUTPUT); // Set pin 8 as output for relay control
}

void loop() {
  if (wg.available()) {
    // Read the Wiegand data
    uint32_t cardNumber = wg.getCode();
    Serial.print("Card Number: ");
    Serial.println(cardNumber);

    // Example: Trigger relay if a specific card number is detected
    if (cardNumber == 12345678) {
      digitalWrite(8, HIGH); // Activate relay
      delay(5000); // Keep relay active for 5 seconds
      digitalWrite(8, LOW); // Deactivate relay
    }
  }
}

Note: Replace 12345678 with the actual card number or fingerprint ID you want to use for access control.

1. Device Not Powering On:

   • Cause: Incorrect power supply or loose connections.
   • Solution: Verify the power supply voltage and ensure secure connections to the 12V and GND pins.

2. Fingerprint Not Recognized:

   • Cause: Dirty or damaged fingerprint sensor, or unregistered fingerprint.
   • Solution: Clean the sensor with a soft cloth and ensure the fingerprint is properly enrolled.

3. Communication Failure:

   • Cause: Incorrect wiring or configuration.
   • Solution: Check the wiring for RS-485 or Wiegand connections. Verify network settings for TCP/IP communication.

4. Relay Not Activating:

   • Cause: Incorrect wiring or logic in the control system.
   • Solution: Verify the relay connections and ensure the control logic is correct.

• Q: Can the AC-5000 be used outdoors?
  A: Yes, the AC-5000 is IP65-rated, making it suitable for outdoor use in most conditions.

• Q: How many users can the device support?
  A: The device can store up to 20,000 fingerprint templates.

• Q: Is there an SDK available for integration?
  A: Yes, Union Community provides an SDK for integrating the AC-5000 with custom applications.

• Q: Can the device be used with RFID cards?
  A: Yes, the AC-5000 supports optional RFID card readers for dual authentication.
