Compact three-call master and multiple door stations for legacy-style commercial audio intercom.
The bill of materials below is tied to live Safsale product cards. Treat it as a starting point and adjust station counts, door-release interfaces, cable topology, PoE, network, mobile/app licensing and call-routing rules to the actual site.

Open toolEstimate network bandwidth from simultaneous audio/video calls and stream bitrates.
Open toolEstimate resident stations, entry panels, masters and network port capacity with expansion headroom.
Open toolCheck switch PoE budget across mixed IEEE PoE device classes.
Open toolVerify entries, stations, cabling, power, network, door release and commissioning.
Open toolEach row opens the live Safsale product card.
The reference BOM uses live Safsale product cards for the main door/entry station, indoor or master stations, and supporting network/cabling items shown on the page.
The page shows a reference endpoint count. Actual capacity depends on the selected platform, power supply, bus/IP topology, licensing, call routing and manufacturer limits.
Many intercom platforms provide a relay or access-control integration path, but the lock, power supply, egress behavior and interface must be verified for the actual door and selected equipment.
Count every PoE endpoint, use the maximum wattage per device, add switch power headroom, and separately calculate simultaneous call bandwidth. Use the Safsale intercom PoE and SIP bandwidth tools as a first pass.
Do not assume cross-brand compatibility. SIP can improve interoperability on some systems, but video, directory, mobile app, relay, licensing and provisioning features are platform-specific. Verify current documentation before mixing products.
Safsale can quote alternate door stations, indoor stations, PoE switching, cabling and access-control interfaces.
