The device description indicates a simple digital panel operated by a microprocessor to monitor pre-selected water properties and trigger alarms based on exceeding limits. There is no mention of learning, adaptation, or complex pattern recognition characteristic of AI/ML. The performance testing focuses on verifying basic alarm functions and accuracy against known standards, not on evaluating AI/ML model performance.
No
The device is an alarm panel designed to notify operators of conditions in a water purification system used for hemodialysis, not to directly treat patients.
No
Explanation: The device is an alarm panel designed to notify operators of conditions within a water purification system. It monitors various water properties and indicates when limits have been exceeded, but it does not diagnose medical conditions or diseases.
No
The device description explicitly states it is a "digital panel operated by a microprocessor" and includes an "LCD display," indicating it is a hardware device with embedded software, not a software-only medical device.
Based on the provided information, the AmeriWater Alarm Panel is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to monitor the performance of a water purification system used in hemodialysis. It alerts operators to issues with the water quality or system function.
- Device Description: The device is an alarm panel that provides visual and audible alerts based on monitored water properties. It does not directly interact with biological samples or provide diagnostic information about a patient's health.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.).
- Providing information for the diagnosis, monitoring, or treatment of a disease or condition.
- Using reagents or other materials to perform tests on biological samples.
The device is a component of a water purification system used in a clinical setting, but its function is to monitor the system's performance, not to perform diagnostic tests on patients.
N/A
Intended Use / Indications for Use
The AmeriWater Alarm Panel is intended for use in hospitals and dialysis clinics as an optional component in the AmeriWater Water Purification System (WPS) for hemodialysis applications. The AmeriWater Alarm Panel is intended to notify the operator of conditions that exist with the Water Purification System requiring the operator's attention. The AmeriWater WPS is intended to remove organic and inorganic substances and microbial contaminants from water. The Purified (or treated) water will then be used to prepare and dilute dialysate concentrate to form dialysate and/or rinse dialyzers for multiple use and/or to prepare dilute solutions for reprocessing procedures in multiple-use dialyzers. The Alarm Panels are designed to meet current AAMI and Federal (U.S.) standards.

Device Description
The AmeriWater Alarm Panel is designed to let technicians and nurses know when something is not functioning properly with the water equipment. The Alarm Panels warn the user by illuminating an alarm light and sounding an audible alarm, indicating that some limit has been exceeded. This submission is for a design change to the existing AmeriWater Alarm Panel cleared for market use in the AmeriWater Water Purification System (WPS) for hemodialysis applications (K991519). The AmeriWater Alarm Panel design has been upgraded from a panel with switches operating relays, to a digital panel operated by a microprocessor. All of the Alarm Panels are provided with an LCD display that will indicate the status of the water system. The nurse's station remote will correspond to what is indicated on the alarm panel. The selection of possible water properties to be monitored has been chosen during the original purchase of this equipment. The properties that this system can monitor include Low Resistivity, High Conductivity, R/O Alarm, Low Storage Tank, and Low Bicarb. There are also 5 additional dry contact inputs provided.
The Low Resistivity alarm warns the user that the measured water the DI tanks is outside of the AAMI standards (1 megohm). The Alarm Panel has two 24VAC outputs that can be used to power solenoid valves to divert the water flow to the drain when the resistivity is below the set-point.
The High Conductivity alarm warns the user that the measured water conductivity is higher than the limit that has been pre-determined by the Facility Director. The Alarm Panel has two 24VAC outputs that can be used to power solenoid valves to divert the water flow to the drain when the conductivity is above the set-point.
The R/O Alarm warns the user that the measured conductivity of the RO is higher than what has been determined to be appropriate by the Facility Director, and has been programmed into the RO controller.
The Low Storage Tank alarm warns the user that the low water float switch has been activated in the storage tank, and that the RO is not producing water flow sufficient to stay above this low water level.
The Low Bicarb Level alarm indicates when the Bicarb Distribution tank is low and may need to be re-filled if use is to continue.
The 5 additional dry contact inputs are labeled IN4 – 8. When one of these receives a closure from the external source, the LCD will indicate an alarm and display the appropriate AUX #. IN4 = AUX2, IN6 = AUX3, IN7 = AUX4 & IN8 = AUX5.
An Alarm Silence function is also provided. The Nurse's Station Remote has a set of lights and audible alarm that will indicate with the main panel in the water room. There is no "Alarm Silence" on the Remote Panel. To silence alarm, it will require the user's attention, in the water room. Using the "ALARM SILENCE" button on the main monitoring panel will "silence" the alarm for 3 minutes only. The alarm will re-indicate 3 minutes after each time it is silenced until the condition causing the alarm has been rectified. In the event that there are multiple alarms active at once, the display on the alarm panel will scroll through the alarms.

The objective of the performance testing was to verify and validate the operation of the new design AmeriWater Alarm Panel for use with the AmeriWater Water Purification System (WPS). The test was conducted on alarm panels with all possible features. Performance testing was conducted on initial production units representing the approved final design of the AmeriWater Alarm Panel. Each of the test units was bench tested to verify that all alarm functions operate as intended. Each unit was tested. simulating normal operation to ensure that all functions operate as intended and meet design specifications and AAM requirements. 24 VAC lights were used to verify operation of 24 VAC outputs. Bench testing was iustified based on the fact that the device does not have any unique interactions with other components in the system. There are no factors that will affect operation of the installed device that cannot be tested in bench testing. Furthermore, 100% of distributed product will be subjected to performance testing prior to shipment.
