SATO MARVEL

SATO MARVEL RFID Hotel Lock with Integrated DND/MUR & Doorbell

PRODUCT OVERVIEW

The SATO MARVEL DND LOCK is an advanced offline RFID hotel lock that combines three essential guestroom functions into a single device:

• RFID Guestroom Door Lock
• Electronic Doorbell
• Electronic Do Not Disturb (DND) / Make Up Room (MUR) Indicators

Unlike conventional hotel systems, the SATO MARVEL eliminates the need for separate wall-mounted DND/MUR panels and doorbell switches, reducing installation costs while providing a modern guest experience. The system operates completely offline using battery power and communicates through RFID cards and hotel management software.
