nurse call light systems nursing homes,An integrated nurse call, fire alarm and building door protection system embodies a central control box and panel at the nurse station having individual room indicator lights and a common buzzer, responsive to individual patient-actuated room switches. Corridor lights are also provided at the doors of individual rooms. The system also embodies building exit door switches which respond to the opening of an exit door to sound the buzzer, thus preventing patients and others entering or leaving the building unnoticed. The buzzer can be silenced by a nurse at the central control panel but the indicator lights must be extinguished in the patients’ rooms and cannot be extinguished from the beds. The fire alarm system features plural zones, each having fire sensing means, a common alarm bell, indicator lights for the zones on the central control panel, and individual testing switches for the zones.
