Optical Smoke Alarm, 10 Year Life-Time Battery

Smoke Alarm 5 Year Warranty Kitemark Sealed battery Battery Silence

Product description

The FireAngel FA6620 Smoke Alarm has been designed to make protecting your home simple, with easy install and rigorous testing by independent parties to ensure quality and longevity.
The optical smoke sensing chamber works by ‘seeing’ smoke as it enters the alarm ‑ making it perfect for slow burning fires where there is thick white smoke. For the fastest response to all fire types search for FireAngel Thermoptek Alarms.

The unit comes with a sealed, tamper proof battery that will last the lifetime of the alarm. The sensor within the unit will deteriorate after 10 years, so to ensure you’re protected we recommend you replace the unit after this time.

  • With optical sensing technology smoke is rapidly detected as it enters the alarm chamber, for a quick reaction to slow burning fires
  • The alarm comes with a sealed, tamper proof battery that will last the lifetime of the alarm (it is recommended that smoke alarms are replaced every 10 years)
  • Featuring a quiet test function which means you’re less likely to wake up loved ones or disturb the neighbours when testing your alarms
  • Give yourself vital time to replace your alarm by silencing low battery warnings for 8 hours using the sleep easy feature
  • Suitable for homes in England and Wales. Not suitable for Scottish homes under the new regulations
  • FireAngel alarms are rigorously tested to ensure unrivalled quality and longevity and come with a 5 year manufacturer’s warranty for peace of mind
  • The perfect replacement for FireAngel ST-622, ST-620 and ST-750 models, this alarm will fit on to the existing baseplate, or can be installed easily using the supplied base and 2 screws

Looking for a FireAngel ST‑622 smoke alarm replacement?
Replace your end of life ST‑622 alarm with a FireAngel FA6615-R Optical Smoke Alarm with 5 year replaceable batteries or FireAngel FA6620-R Optical Smoke Alarm with 10 year sealed for life battery, without requiring a new base plate or leaving unsightly holes in your ceiling.

Looking for a FireAngel ST‑620 smoke alarm replacement?
Replace your end of life ST‑620 alarm with a FireAngel FA6615-R Optical Smoke Alarm with 5 year replaceable batteries or FireAngel FA6620-R Optical Smoke Alarm with 10 year sealed for life battery, without requiring a new base plate or leaving unsightly holes in your ceiling.

You will need to replace your baseplate for this alarm when replacing any end of life devices.

You may find the baseplate for your alarm is a little snug, which means it will need extra force to secure when fixing to the alarm. If the ‘lugs’ at the rear of the alarm can be seen, then the alarm will be secure and can be installed. However, if you’re unable to turn the baseplate enough for these to be seen then we can offer an alternative baseplate.
