Our 10-year sealed optical smoke alarm, currently our best selling unit in our First Alert battery alarm range, utilizes photoelectric or optical sensing technology, so you won’t have to worry about steam, burn toast, or cooking particles setting it off needlessly. For such a small unit – it has a depth of 38mm and a diameter of 100mm – it can produce an incredibly loud alarm sound, at 85 decibels. It comes with a large hush/silence button for easy operation. The package also includes an instruction manual, a sealed lithium battery with a 10-year life, and fixing screws. The 10-Year sealed optical smoke alarm is also covered by a 10-year manufacturer’s guarantee.
Optical alarms are suitable for smouldering fires and material and should be used in bedrooms and living rooms - a house should have a combination of optical and ionisation
