While smoke alarms are installed in 96 percent of US homes, 20 percent of those alarms are not functioning, mainly due to dead or missing batteries. Moreover, two-thirds of residential fire deaths occur in homes without smoke alarms or in homes with non-functioning smoke alarms.

With a sealed, long-life lithium battery smoke alarm, homeowners can enjoy peace of mind knowing that their homes’ smoke alarms are always on – operating 24 hours per day, seven days per week for upto 10 years – that’s a decade of hassle-free protection.
