Avoid Fire Hazards

With the increase of people staying home, there has been an increase of house fires.

The risk of dying in a residential fire is cut in half in houses with working smoke detectors. The US National Fire Protection Association reports 0.53 deaths per 100 fires in homes with working smoke detectors compared to 1.18 deaths without.

"The amount of money it takes to buy those smoke detectors is a little bit of money for the big return on saving somebody’s life"

Complete Home Protection

Industry experts (such as the NFPA), recommend that photoelectric smoke alarms be installed to help ensure maximum detection of the various types of fires that can occur within the home.

Ensure whole home family protection by placing 1 fire detector on each level of your home, in your bedroom, & other locations where required by law.


The battery of GS528A is one year replaceable battery. But the product can be 10 years life time which is longer than other smoke detectors.
