Questions about alarms include where they need to be located in the house, whether they need to be hardwired, and how often they should be replaced. Fortunately, Oregon real estate brokers help ensure that the correct type and number of alarms are installed in a home prior to sale. However, some people live in their homes for years and simply replace the batteries when the alarms start their wonderful chirping. That may not be the best long-term solution. If your smoke and carbon dioxide alarms have been up so long that they’re turning yellow, it may be time to replace them.
For more in-depth information, the Oregon Fire Marshal’s website has Frequently Asked Questions about smoke alarms and carbon monoxide alarms. If you click those links and scroll down on the website, it should help you sort out where the alarms need to be (by level and room in the house) and how often they should be replaced (when no longer functional or every 10 years). Alarm manufacturers include information on where the alarm should be attached (e.g., wall/ceiling).
