First Alert Interconnect Hardwire Smoke Alarm

No, this specific model is designed exclusively for smoke detection. It does not monitor for carbon monoxide, so you will need a separate detector for that purpose.

When you wire multiple units together, they function as a single system. If one alarm detects smoke and triggers, every other interconnected alarm in your home will sound simultaneously, providing an early warning regardless of where the fire starts.

This model uses advanced sensing technology specifically calibrated to reduce nuisance alarms caused by cooking smoke. While no detector is completely immune to steam or heavy smoke, this unit is designed to distinguish between common kitchen activities and actual fire hazards.

No, this model features a 10-year sealed battery backup. You do not need to change the battery for the life of the alarm, which simplifies maintenance and ensures continuous protection during power outages.

The unit includes an end-of-life warning signal that will alert you when it is time to replace the device. This ensures you are never left unprotected due to an expired sensor.

This alarm is versatile and can be mounted on either the ceiling or the wall, depending on your home's layout and wiring access.
