🛑 Quick Answer & Replacements:

To install new SMART Pads II, firmly pull the old gray connector plug out of the top port of your FRx AED. Take your new pads, leave the gray foil pouch sealed, and push the new gray connector firmly into the port until it clicks. Verify the AED’s status indicator begins flashing green.

When it is time to replace the expired defibrillation pads on your facility’s AED, doing it correctly is a matter of strict safety compliance.

If the connector plug isn’t seated properly, or if the installation isn’t logged correctly, you risk the AED failing its daily diagnostic tests—or worse, failing during a sudden cardiac arrest emergency.

Whether you are a school nurse performing routine maintenance or a safety officer replacing pads after a deployment, here is the comprehensive guide to installing, testing, and logging your new Philips HeartStart FRx SMART Pads II.

1. The Engineering: Why Must They Be “Pre-Connected”?

Unlike older generations of defibrillators where pads were kept completely separate from the machine until an emergency occurred, the Philips HeartStart FRx operates on a “Pre-Connected” safety philosophy.

You must plug the new pads into the AED before stowing it in your cabinet for two critical reasons:

  1. Time to Shock: In a cardiac emergency, survival rates drop by 7-10% for every minute that passes. Pre-connecting the pads eliminates the need to fumble with plugs while a patient is in distress. You simply turn the machine on and pull the pads out.

  2. The Daily Self-Test Loop: The FRx performs rigorous automated self-tests daily, weekly, and monthly. By keeping the pads plugged in, the AED sends a microscopic electrical pulse through the wires to verify electrical continuity. If the pads are unplugged or the internal wires are damaged, the AED will immediately alert you.

2. Step-by-Step Installation Instructions

Follow this procedure to safely swap out your old pads and reset your AED’s safety loop:

1.Unplug the Expired Pads:

Locate the gray connector plug currently seated in the top-center port of your FRx defibrillator. Firmly pull the plug straight up and out. Remove the old, rigid gray plastic case containing the expired pads from the red carrying bag and discard them.

2.Inspect the New SMART Pads II:

Unbox your fresh replacements. Do not tear open the gray foil pouch. The pads must remain vacuum-sealed to protect the water-based hydrogel. Verify the 2-year expiration date printed next to the hourglass (⌛) symbol on the front of the foil.

3.Seat the New Connector Plug:

Take the gray connector plug attached to the new pad case and firmly push it into the top port of the FRx. You must push firmly until you feel it click or seat fully into the recess. A loose connection will cause the AED to fail its immediate self-test.

4.Stow and Position the Pink Key:

Slide the rigid gray pad case back into the designated pocket inside your red FRx carrying case. Ensure the connection wire is neatly tucked and not stretched or kinked. If your facility uses the pink Infant/Child Key, ensure it is securely tethered to the carrying case strap so it is immediately accessible during a pediatric emergency.

3. Troubleshooting: Verifying the Green “Ready” Light

Once the new pads are firmly plugged in, the AED will immediately recognize the new connection and run a background diagnostic check. You must visually verify this check is successful before walking away.

Look at the status indicator light on the front of the FRx:

  • Flashing Green Light: Success. The AED has verified the connection, passed its diagnostic continuity check, and is fully Rescue Ready.

  • Solid Red Light, No Light, or “Chirping” Beeps: The AED has detected an error. In most cases during installation, this means the gray plug is not pushed in far enough. Pull the plug out, check the port for any dust or lint, and forcefully push it back in. If the chirping continues, press the flashing blue “i” button for a vocal diagnostic report.

4. The Final Step: Compliance Logging

Replacing the pads is only half the job of a safety manager. To protect your organization from liability, the pad replacement must be officially documented.

Open your facility’s AED inspection logbook or compliance software and record:

  1. The date the new pads were installed.

  2. The name/signature of the inspector.

  3. The new expiration date printed on the SMART Pads II pouch.

  4. Confirmation that the status indicator is actively flashing green.

Need to Restock Your Pads?

Never wait until your AED starts chirping to source replacement equipment. Supply chain delays can leave your organization unprotected and legally vulnerable.
