Since 1976, First Alert has been providing protection for homes. The company launched with battery-operated smoke detectors, then followed in 1996 with carbon monoxide alarms. Over the years, it has continued to introduce dependable home safety products that include home security systems, safes and more.
First Alert has a solid reputation for providing dependable smoke alarms and carbon monoxide detectors. While these products don’t necessarily come with all the bells and whistles that some other alarms do, there is an array of affordable choices that consumers can trust. The company, which is part of BRK Electronics, is headquartered in Illinois and has offices around the world.
First Alert smoke alarms and carbon monoxide detectors are a good option to consider for homeowners who don’t want to spend a lot of money but still want to protect their homes and families. They are also an excellent choice for senior citizens and others who may be hard of hearing, as some First Alert alarms have frequencies that make it easier for them to hear.
Pros
- Both hard-wired and battery-operated options: While some people prefer a smoke or CO alarm that is hardwired into their home, others prefer the flexibility that battery-operated models offer. First Alert offers an array of both types.
- Photoelectric and ionization sensors: When it comes to smoke sensors, there are two kinds used in alarms to detect fires—photoelectric and ionization sensors. Photoelectronic sensors use light and are best to detect fires that are moving quickly. Ionization sensors are better at detecting fires with more smoke than flames. First Alert offers models that feature each, and some that feature both, so you can make the best choice for your home.
- One-stop home security shop: First Alert sells a full range of products to keep your home safe beyond smoke alarms and carbon monoxide detectors. It also sells motion detectors, escape ladders, safes and home security systems, which is a bonus for people who prefer to deal with companies to cover all their home security needs.
Cons
- False alarms: While most customer reviews of First Alert smoke alarms and carbon monoxide detectors are positive, there are some complaints about occasional false alarms and random chirping, which can be frustrating, particularly if they go off in the middle of the night.
- Aesthetics: If you’re looking for sleek, sophisticated design, First Alert alarms may not fit the bill. While they have an array of models to choose from, most are basic and traditional in design.
