KCS-RFID-BK circuits such as lighting, sockets, and HVAC systems.

It is typically used as part of a GRMS (Guest Room Management System) to implement energy-saving strategies and automate room status detection. The device is adapted for EU installation standard (round Ø60 mm wall box).

• RFID card detection – detects presence of guest via RFID card insertion.
• Integrated relay output – controls room power supply.
• Energy saving functionality – automatically switches off power when card is removed.
• Wide voltage support – compatible with 110–240V AC systems.
• LED status indication – visual feedback of operation state.
• EU mounting standard (Ø60 mm) – compatible with standard European round wall boxes.
• Waterproof front panel – suitable for hotel environments.
• Simple installation – flush mounting.

Power control:

• Device switches room power via internal relay or external contactor.

GRMS integration:

• Can be used as presence signal (guest in room).
• Integrated into energy-saving logic (lighting, HVAC, sockets).

Installation recommendation:

• For higher loads, use external contactor controlled by the switch.

Card compatibility:

• Requires compatible RFID cards (13.56 MHz standard).

System behavior:

• Relay activates when card is inserted.
• Relay deactivates after card removal with optional delay.
