Automatic door units with this logotype support the network system using CAN communication.
NABCO is the first door brand that adopted the internationally standardized network technology using CAN communication into automatic door systems.
Information networking among not only automatic door units but also optional devices, such as sensors and electric locks, has improved security and reliability, and we propose the best maintenance plan using the maintenance data that we have accumulated and managed.
