The AY-K35 is justly called the Multi-Smart reader! It features multi-technology and OSDP secure channel communication to bring more versatility, scalability and security to physical access control – without the need to replace existing credentials.

The reader is now more protected than ever. It is dust and water resistant, including vandal proof and anti-microbial properties to reduce the risk of contamination while increasing physical access control security.

AY-K35 supports NFC and BLE mobile credentials, for better user convenience, in addition to 125 kHz FSK and ASK, 13.56 MHz and MIFARE Classic® Sector credentials. With AY-K35, organizations of all sizes can easily optimize their credentials strategy to accommodate users on an individual profile level – reducing operational costs without compromising on security or functionality.

X-DA High Efficiency Power Amplifiers are High Efficiency Power Amplifiers which is the perfect choice for safety required applications

When a fault, self-protection or self-testing happens, its audio input fault port on the rear panel will short circuit and a fault signal will then be sent to the control unit in the network. When a shout circuit is detected in the main power supply circuit, the power will be automatically shut down. The backup power supply will then be enabled to replace the main one. The device adopts lightweight design. The front panel is made of UL94V-0 fire proof ABS material, protecting the machine under extreme conditions. A cooling fan is equipped for heat exhaustion so that the machine can maintain high working efficiency. The amplifier can work without main power in emergency
