How to Replace the Battery in the FireX Smoke Alarm PADC240 – an Illustrated Tutorial in 19 Steps

Hazards
More accidents happen at home than anywhere else. Replacing the battery of a smoke detector is not without hazards. Make sure you know what you’re doing. The FireX smoke alarm PADC240 is mains-powered and connected to your 110 volt or 220 volt home electrical system. The 9 volt battery only serves as backup in the event of a power failure. Since smoke alarms are placed at ceilings, there’s also a risk of falling. If the battery is not replaced correctly, it might not work properly.

  • Read our disclaimer
  • Read the official manual
  • Hire a qualified electrician if insecure

When is replacement of the battery needed?
The alarm will chirp at random intervals to indicate that the backup battery is running low and needs replacing. However you should replace smoke alarms, when they are ten years old or sooner if they don’t respond properly when tested.

Necessaries
To replace the battery of the FireX Smoke Alarm PADC240, you need:

  • New high quality, long lasting 9 volt battery, NOT a rechargeable one
  • Small screwdriver
  • Step Ladder

6. Carefully unplug the cable without damaging any wired connections. The beige connector plug with the three wires should pull straight out. It’s probably tight but that’s what you need to do to get the battery compartment open. We did NOT have to push, pull or squeeze plastic “catches” or buttons to release the connector plug, but we had to use muscle power. If you can’t get enough grip on the connector plug with your fingers, you might use waterpump pliers to get it off, but do this at your own risk!
