Read Before Installing or Using This Device

This device has been designed for integration into professional access control systems in residential, commercial, or industrial buildings. It must only be installed and handled by qualified technical personnel, in accordance with the manufacturer's specifications. Improper use, unauthorised handling, or incorrect installation may cause serious harm to persons or property, and will void both the warranty and the manufacturer's liability.

Electrical Safety

Before connecting, disconnecting, or intervening with the device, ensure the power supply is completely switched off. Although this product operates at low voltage (e.g. 12–24 VDC), improper handling can cause short circuits, door damage, overheating, or risk of electric shock.

Intended Use and Compatibility

This device is suitable for wooden, metal, or aluminium doors, depending on the model. Certain models are certified for use on fire doors and emergency exits. Always verify the specific certifications and compatibility before installation. Use in environments exposed to water, heavy dust, or aggressive chemical agents is not recommended unless the device is properly certified (e.g. IP65, IP68 etc.).

Maintenance and Use

Do not open, modify, or tamper with the interior of the device. Any unauthorised intervention will automatically void the warranty. Cleaning should be carried out using soft cloths and non-abrasive products. Periodic maintenance by a qualified technician is recommended, particularly in high-usage environments.

Limited Warranty

This product is covered by a commercial warranty against manufacturing defects for the period specified by Openers & Closers. The warranty does not cover normal wear and tear, incorrect installation, tampering, mechanical impacts, or unsuitable environmental conditions. Openers & Closers shall not be held liable for indirect damage, financial loss, or harm resulting from improper or non-compliant use.

Regulations and Compliance

This product complies, where applicable, with relevant regulations in each market (e.g. CE, RoHS, WEEE, UL 294, NFPA-80, EN 14846). Refer to the product labelling and technical documentation to confirm specific certifications.

Disposal and Recycling

This device contains electronic components and must not be disposed of with household waste. It must be taken to an authorised collection point for electrical and electronic equipment (WEEE). The crossed-out wheeled bin symbol indicates this legal requirement. The packaging is recyclable and should be disposed of in accordance with local regulations.

Only supports copying the card user and PIN code user data

  • Both devices must be manufactured by us and support this function.
  • The admin code for both devices must be the same.
  • Connect the Wiegand cables of both devices and power on
  • Eg. For device A and B, they have the same admin code. Add a new card & code user to the device A. Device B has no user. Connect the Wiegand cable of device A and B and power on. Do the operation of * admin code # 9 # 1 # on device A. The green LED of the two devices flash. The device A is sending the user data to device B.

Factory reset registering new administrator card

StepsOperation
1Turn off the device and connect the OPEN1 (yellow) wire to ground.
2When you turn it on, the keyboard will beep twice. At that moment, disconnect the OPEN 1 ground wire. Insert the administrator card and press the administrator's fingerprint sensor three times.
