===== General description =====

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).


===== Features =====

  * **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.

===== Integration Notes =====

**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.
