Designing specifically for elevator control, the EX16 floor extension boards provide customers with the most secured, scalable, versatile and affordable access control solutions available today. Floor access can be restricted based on various user credentials, including fingerprint, proximity card and/or password. Pre-defined time schedules can also be used to control floor access. During normal visits/business hours, unrestricted floor access can also be permitted (aka Passage mode). The EX16 Elevator Floor Extension Board restricts access up to an additional sixteen floors. Each EC10 can support up to three EX16 boards. When combining together, a total fifty eight (58) floors can be controlled with a single EC10 bundle.
