The Air Access AA-GATEWAY is a Gateway communication device used within the Air Access wireless system. It is fully compatible with Alarm Lock's wireless ArchiTech Networx devices, including the NETWORXPANEL wireless control panel and Networx Expanders. The Air Access model AAGATEWAY-PW includes a UPS (Uninterruptible Power Supply) and battery back up. The Air Access system allows you to upload and download lock programming features wirelessly, using the cloud-based Air Access Cloud Web Portal. As shown in the illustration below, the connection to the Air Access Cloud Web Portal is made through a secure Internet connection (cloud). The Web Portal is then connected through a secure cellular connection to an Air Access communicator (e.g. the series model AALTEA) that can be wired to up to 1-6 AA-GATEWAYs (no switch is required if connecting to only one AA-GATEWAY). Each AA-GATEWAY can communicate to up to 63 door locks via a private wireless signal. In this way, the Air Access software allows for secure control and programming of each wireless door lock in the system.
