Magnetic card holder to detect room occupancy status

• Optical sensor detects the presence of a card in the magnetic card holder

• Transfers "room occupied" signal to HRC3.. room controller

• Integral LEDs to guide guests or staff upon entry

• Built-in speaker for three-tone chimes for the doorbell feature (HML3.1/A only)

Application

The HMH3.1/A or HML3.1/A magnetic card reader is used in conjunction with a HRC3..

room controller. The HMH3.1/A and HML3.1A card holders register the presence of

guests or hotel-staff and transmit this information to the HRC3.. room controller for

evaluation. The HRC3.. room controller activates the pre-programmed occupancy-

dependent room functions in the hotel room in accordance with the room occupancy

status (guest(s) in the room, hotel staff in the room, or room empty).
