Heartsine Samaritan PAD 360P

IP56 means the HeartSine 360P is fully dust-tight and protected against powerful water jets from any direction. It survives sports-field rain, marina spray, construction dust, pool deck humidity, and outdoor weather exposure year-round. That’s stronger than the IP55 rating on the Philips FRx, ZOLL AED 3, and Powerheart G5. It is not submersible — never drop it in water. For most real outdoor use cases including unconditioned outdoor cabinets, IP56 is the right rating, and the 360P is one of the lightest IP56 AEDs on the market at 2.4 lb.

For untrained rescuers, fully-automatic AEDs like the 360P are usually safer because they remove the button-press hesitation that defeats many real-world rescues. The device delivers the shock automatically after countdown prompts, eliminating the moment a panicked rescuer freezes. Semi-automatic devices require a deliberate button press, which trained responders prefer because it gives them final control. For churches, senior living, construction sites, and any environment where the rescuer is most likely a first-timer, fully-auto wins.

Pay the $300 only if you need outdoor IP56 durability or fully-automatic shock delivery. The 350P at $995 is also IP56 but semi-automatic, lighter weight, and lower-cost. Both share the same Pad-Pak cartridges and 8-year warranty. The 360P’s two genuine upgrades are the fully-auto workflow for untrained-rescuer environments and slightly more rugged housing. For indoor offices, the 350P is the better value. For outdoor sites with untrained crews, the 360P pays back in reduced rescuer hesitation.

Yes — IP56 protects against rain falling on the cabinet and even powerful water jets during a rescue. Sports-field rescues during downpours, marina deck rescues during spray, and outdoor venue rescues in inclement weather are all within spec. You should still avoid sustained submersion, but ordinary outdoor weather exposure is exactly what the 360P is rated for. Keep the cabinet door closed when not in use and the device will tolerate years of mounted outdoor exposure without degradation.

No — the 360P still announces a clear-the-patient countdown before delivering the shock. You hear “stand clear, analyzing rhythm” followed by “shock advised, stand clear” with a 3-second window to step back. The difference vs semi-automatic is that no rescuer button-press is required; the device delivers the shock automatically after the countdown finishes. AHA-recommended clearing safety is built into the workflow — fully-auto removes one friction point without compromising patient or rescuer safety.
