TWire-Free Smoke Alarm System
Wire-free smoke alarms are equipped with lithium-ion batteries, ensuring they continue functioning even during power failure. This makes them an excellent option for homeowners in areas prone to power outages. With wire-free smoke alarms, there is no need to do any wiring during installation. They are easy to install and can be placed anywhere in the house, making them a flexible and convenient option.

Hardwire Interconnect Smoke Alarm System
Hardwire interconnect smoke alarms, also known as wired smoke alarms, are designed to be hardwired into your home's electrical system. These systems come with a backup battery, ensuring they remain functional even during power outages. The interconnect feature ensures that all smoke alarms installed in your home sound off simultaneously, giving you more time to evacuate.

Which System is the Best Option for Your Home?
Choosing which system is the best for your home depends on your individual needs and preference. Wire-free systems are easy to install and portable, making them a perfect option for older homes or rental properties. Another advantage of wire-free smoke alarms is that you don't need to consider the installation location, placement or accessibility, making them convenient for anyone.
However, hardwire interconnect smoke alarms are a more permanent option and can be incorporated into new construction projects. They also allow for simultaneous activation when a smoke alarm is triggered, providing extra safety for you and your family.
