Key Features of the DefiSign Semi-Automatic Defibrillator
Instant Activation in Seconds
Simply lift the front cover and the DefiSign powers on instantly. No buttons, no complicated menus, no confusion, just immediate, clear instructions in plain English.
Visual LED Guidance + Audio Instructions
Dual guidance system removes all guesswork:
- Audio: Clear spoken instructions in your chosen language
- Visual: Illuminated LED images show exactly where to place pads, how to position hands for CPR, when to stand back
Perfect for noisy environments (gyms, factories) where audio alone might not be heard.
Pre-Connected Electrodes Save Precious Time
The electrode pads are visible, accessible, and already connected. No fumbling with packaging, no searching for connection points. This feature matters because if survival drops 10% per minute, saving 30 seconds could improve survival chances by 5%.
Industry Leading 10-Year Warranty
Most defibrillators that offer 5–8 year warranties, the DefiSign LIFE is backed by a full 10 year manufacturer's warranty. This exceptional coverage provides peace of mind and demonstrates the manufacturer's confidence in the device's long-term reliability.
Multilingual Support for International Environments
The DefiSign defibrillator comes pre-loaded with three languages, including English, Swedish, and German. With a single press of the language button, you can switch languages, even during CPR, without interrupting the rescue sequence. This makes it perfect for:
- Railway stations and airports
- Holiday parks and tourist attractions
Other language combinations are available upon request.
Readiness Indicators
Four LED status lights on the front of the device provide instant visual confirmation of operational status:
- Green flashing LED (right side): Device is ready for emergency use
- Illuminated LEDs (left side): Action required (e.g., battery or electrode replacement)
This intuitive system ensures you can verify your AED's readiness in seconds during routine checks, essential for ensuring this portable defibrillator remains functional when needed.
Automatic Monitoring
Regular self-tests check battery status, electrode connection/capacity, and overall functionality. The LED status indicator and radio frequency identification tracking mean you'll always know when maintenance is due, ensuring this portable defibrillator remains ready as the nearest defibrillator to an emergency.
Weatherproof Design (IP55 Rating)
With high dust and water resistance, the DefiSign LIFE can be installed both indoors and outdoors. For outdoor placement, we recommend pairing it with a suitable heated outdoor defibrillator cabinet to protect against extreme temperatures and ensure it's always ready as the nearest defibrillator for passersby.
Low Asystole Threshold
Detects even the faintest heart activity so the defibrillator can correctly tell the difference between a real flatline and very weak heart activity, so it won’t miss a shockable rhythm.
Pacemaker detection
Automatically recognises implanted pacemakers and adjusts analysis accordingly.
Adapted Child CPR Protocol
When the paediatric pads are plugged in, the AED automatically switches to child-appropriate CPR coaching and shock settings, helping rescuers confidently treat children in emergencies.

- Observe LED visual prompts – Illuminated images reinforce each step.
- Apply electrode pads – Place pre-connected pads on the victim's bare chest as shown by the LED guidance.
- Allow analysis – The device automatically assesses the heart rhythm.
- Deliver shock if advised – If shock is advised, the device announces "Shock advised. Stand Clear. Shock will be delivered in 3...2...1.." Shock is delivered automatically (you don't have to do anything.
- If no shock advised – Device announces "No shock advised", and you proceed to CPR as the device coaches you.
The entire process is designed to be completed by someone with no medical training. An AED saves lives by being simple enough for anyone to use. However, we recommend all staff complete a basic defibrillator and CPR training course focusing on AED first aid skills for maximum confidence.
Is the DefiSign LIFE the same as the Schiller FRED PA-1?
Yes, the DefSign LIFE and Schiller FRED PA-1 are identical devices. DefiSign is manufactured by Schiller, a respected Swiss medical technology company. You're receiving the same proven technology, quality, and 10-year warranty regardless of which name is on the device.
Is the DefiSign LIFE suitable for outdoor use?
Yes, with its IP55 rating, the DefSign LIFE resists dust and water ingress. For outdoor installation, making it the closest defibrillator for a wider community, we strongly recommend housing it in a heated outdoor defib cabinet to protect against temperature extremes and ensure year round reliability.
How do I know where to put the defibrillator pads?
The DefSign LIFE makes this simple. The device provides clear audio instructions in defibrillator English (or your chosen language) explaining defibrillator where to put pads, while LED visual prompts illuminate diagrams showing exact placement. The electrode pads themselves also have visual diagrams printed on them.
Where should the defibrillator pads be placed?
For adults and older children, one pad is placed on the upper right of the chest and the other on the lower left side of the chest, as shown on the pad diagrams and illuminated images on the device. For younger children, the paediatric pads include clear illustrations showing the correct pad placement for a small chest.
What languages does the DefiSign LIFE support?
Each unit is supplied with three pre-configured languages, such as English, German, and Swedish, and alternative language combinations are available on request. The rescuer can switch language with a single button press, even while a rescue is in progress.
Can an AED be used on children?
Yes, an AED can be used on anyone experiencing cardiac arrest. With standard adult electrodes, the DefSign is suitable for anyone over 8 years or weighing more than 25kg. For younger children, simply attach the optional paediatric electrodes, which automatically adjust the shock energy appropriately.
