The standalone code lock combines the functions of a digital access control keypad and a card reader, as well as proximity tags. This modern device works with electromagnetic locks that utilize an access control system. It can also control other electrical or alarm devices. The lock features a relay output and a card and proximity tag reader. Authorized individuals can enter the room or building after scanning their card or entering the access code. The non-volatile EPROM memory retains stored codes and parameters even when the power supply is interrupted. The keypad of the lock is backlit, making code entry easy even after dark. Due to its durable housing, it is extremely resistant to changing weather conditions. The lock is suitable for surface mounting. LEDs indicate the operational status of the encoder.
