Patient stations are located in the patient's room and provide the patient with a convenient means of originating a call to the nurse station. The patient can also engage in hands-free two-way communications with the nurse.

Duty stations have audio-visual indicators for the presence of three different levels of calls in the system: normal, emergency and staff emergency.

Staff stations provide the staff members with the facilities for engaging in two-way voice communications with the nurse control station. These types of stations are usually installed in examining rooms, day rooms and other service or public areas where communication is required between medical staff members and the nurse at the nurse control station.
