Frequently Asked Questions (FAQs)
What should be avoided during smoke alarm installation?
For installation, smoke alarms should not be placed near ducts, doors, or windows, since the draft coming in can interfere with whether it is able to properly detect smoke and fire. Once installed, it’s important to also avoid doing anything that may prevent it from working. This can include avoiding painting the smoke alarms or placing decorations or stickers on it.
Where do smoke alarms need to be installed?
For smoke alarms to work as intended, they need to be installed in the correct locations to detect threats. Therefore, they need to be mounted on high walls and ceilings, since smoke from fires rise to high places. For alarms mounted on walls, they should be installed no more that 12 inches away from the ceiling to ensure they are placed high enough. Of course, where smoke alarms need to be installed can be unique depending on the structure of your ceilings and what the layout of your home looks like, which is why it’s best to consult a professional.
When should I replace my smoke alarm?
Generally, smoke alarms should be replaced every 5-10 years. The exact timing depends on the type of smoke alarm and its power source. For example, some smoke alarms come with non-replaceable batteries set to last for 10 years. Once the battery runs out, the entire alarm needs to be replaced. Other alarms (such as those with replaceable batteries) should be renewed every 5 years if necessary.
