The IX-SSA Aiphone is a flush mount IP audio door station. It is weather resistant (IP65) and connects to the network using Cat-5e/6 cable. It is SIP compliant and can be used with or without other IX Series stations. Audio can be captured on a microSD card. The station can be programmed to call up to 20 different stations with three different call levels to choose from. The station has a 600Â¦ output that can be used for paging or communication. There are two contact outputs that can be programmed to trigger during door release, when the 600Â¦ output is used, or based on the status of the station. There are six inputs that can be used to trigger an outgoing call or answer a call/page. Sound files can be uploaded for custom messages to be played during certain functions (door release, call placed, communication start, error message, etc.). The stations have audible and visual indications for calling, communication, and door release. Datasheet IX-SSA.
