3-Channel Relay Smart BMS Client

Yes. Lighting, curtains, thermostats, scenarios and schedules, home modes, music, the door intercom, paging and the prayer-time announcements all run on your local network inside the console, so they carry on without internet as long as the building's own network (the switch and the router or access point) is powered. You can control everything from the wall console and from any phone or laptop on your Wi-Fi through the console's web page. Internet is needed only for features that reach outside the building: remote access with the KDT cloud app, phone notifications while the app is closed, internet radio, weather and automatic updates.

The KDT smart home (the Iridium family) is built from a central console, wall and desktop touch panels, and relay modules. From this one system you can control lighting, curtains, fan coil, ducted split and evaporative cooler thermostats, music on IP speakers, the door intercom and the Rhenium alarm panel. Scenarios, schedules and home modes such as presence, away and night are set up in the same place. Everything runs on your local network, and the KDT cloud web app adds control from outside the building.

The console, either the KD-SC10-PW 10-inch wall unit or the KDT console software on a Windows or Linux PC, is the brain of the system: it runs scenarios, schedules, thermostats and home modes and serves the web interface. The 4-inch touch panels, the KD-CC04-R03 for the wall and the KD-CC04-D for the desk, are control points for lights, thermostat, music and modes. The relay modules KD-R004, KD-R008, KD-R016 and KD-R032, with 4, 8, 16 and 32 channels, do the actual switching of lights, curtain motors and fan coils in the electrical cabinet. The KD-CC04-R03 also has 3 built-in 10 A relays of its own.

Count 1 channel per lighting circuit, 2 per curtain motor (open and close) and up to 3 per fan coil (low, medium and high speed), plus 1 more if you also switch its water valve, then add about 20 percent for future changes. For example, 14 lighting circuits, 3 curtains and 3 fan coils (without valves) need 14 + 3 × 2 + 3 × 3 = 29 channels, and with 20 percent spare about 35. That is covered by one KD-R032 (32 channels) plus one KD-R004 (4 channels). Each module also has as many digital inputs as it has relay channels.

Yes. The KDT console software can also be installed on Windows and Linux computers, where it acts as the system's central console. The PC must run around the clock, so put it on a UPS, disable sleep mode and, on Windows, turn on automatic sign-in so that the console starts again by itself after a power cut. Functions that rely on the operating system or hardware, such as Bluetooth phone audio, may differ between a wall console and a PC. Other devices on the network keep using the console through its web page as before.
