The EEI 900-119 Lavatory-Emergency Station components are electrically isolated from the single gang plate for proper mounting into a one gang box. By gently pressing the switch or pulling the cord downward an emergency call is placed on the system using independent circuits or those of the patient station if in the same room. Cancellation of the call is always from the originating station by pressing the switch in the upward position. The call assurance LED is red and is activated when the switch is in the downward position.
