7、What Buyers Must Specify for a Hotel Automation System
A hotel automation RFQ should allow an engineer to count every input, output, interface, and room variation.
7.1 Room types and quantities
Do not send only the total room count.
A hotel with 300 rooms may contain standard rooms, accessible rooms, suites, connecting rooms, executive rooms, and apartments. Each type can have a different number of lighting circuits, panels, curtains, HVAC outputs, sockets, sensors, and scenes.
Prepare a room-type matrix.
7.2 Lighting schedule
State the number of switched circuits, dimming circuits, load types, maximum channel loads, control locations, emergency-lighting exclusions, and required scenes.
Write “three switched circuits and two dimming circuits” instead of “smart lighting.”
7.3 HVAC equipment
State whether the room uses FCU, VRF, split AC, or another system. For an FCU, identify the pipe arrangement, fan speeds, valve type, valve voltage, heating and cooling logic, window-contact response, and BMS points.
The New Delhi project had to address seasonal switching between cooling and heating. The integrator later created a central mode-change program because the original piping arrangement required the room temperature controllers to change operating mode. That modification came after the building began operating.
7.4 Curtains and blinds
State the motor type, voltage, control contacts, number of motors, and required actions: open, close, stop, preset position, or percentage control.
7.5 Sensors and hotel functions
List door contacts, occupancy sensors, bathroom sensors, key-card inputs, DND, Make Up Room, doorbell, door-number plate, minibar supply, and essential sockets.
7.6 Protocol and network
State whether the project uses KNX, RS485, Zigbee, Wi-Fi, BLE Mesh, a proprietary protocol, or a hybrid architecture. Add device quantities, gateway locations, addressing rules, network ownership, remote access, and offline requirements.
7.7 Panel requirements
State the wall-box standard, dimensions, material, finish, button quantity, labels, language, backlight, logo, and sample approval process.
NaLite’s current 3.5-inch hotel-control-panel page, for example, lists an 86-box format, multilingual interface, offline operation, and customizable lighting, curtain, AC, and scene controls. These are not decorative claims to paste into every project. They are four specification fields that must be checked against the actual room drawing and tested in the sample room.
