The EC33 controls the elevator using its network-connected relays, providing a smart access control solution for the building. It integrates with Akuvox intercom products to manage access to the key-fobbed elevator. Administrators can configure comprehensive access control settings, including relay control, relay scheduling, card management, and emergency security measures. The device can be deployed, upgraded, configured, and maintained remotely via web-based or cloud-based operations. Additionally, it can be connected to third-party card readers through the Wiegand interface for card-based elevator entry control. Users can grant access to guests or visitors and guide them to the designated floor using the indoor monitor or the SmartPlus mobile app. Furthermore, users can access the building elevator on their current floor using an RFID card on the door phone.
