I change the batteries in my smoke detector every 6 months.  My question is, is there ever a reason to replace a working smoke detector?  The four I have are 22 years old and still beep when I test them semi-annually.

The National Fire Protection Association recommends that ALL smoke detectors be replaced at least every ten years, even if they still seem to be working.  Over time, dust gathers on the sensors, making the smoke alarm less capable.  In the event of a fire, every second counts and the sensors in smoke alarms need to be crisp.  Even though the smoke alarms beep during testing, the sensor does deteriorate over time and the smoke detector should be replaced.  

When replacing your smoke alarm, you should consider advancing the protection of your home.  A hardwired smoke detector can be linked together so that if one smoke detector goes off, every detector in your home will sound. If a fire starts in the basement at the electrical panel while you are sleeping, the smoke alarm in your bedroom will rouse you awake and allow you time to escape safely.   

We offer the very popular First Alert 9120B that can connect with up to twelve other smoke alarms when wired together. 

If you don’t desire the expense and hassle of running wire to all the smoke alarms, we also sell a wireless system.  The base unit (First Alert SA520B) is hard wired, while up to 12 (First Alert SA511B) wireless units just require a battery to connect to the base and provide whole house protection.  

These smoke alarms feature a "Spread Spectrum Horn Tone" which produces a lower and varying frequency making it easier for the elderly with normal aged related hearing loss to hear the horn.  They also have a voice alarm with programmable locations.

We also offer the battery powered First Alert FG250B, which is the professional standard for smoke alarms.   It can not be interconnected, but also does not require any hardwiring.  It has advanced sensor technology and a hinged cover design that offers fast and easy installation and battery replacement.
