An interlinked smoke alarm is a system of smoke detectors that are connected wirelessly or through a hardwired network. When one alarm detects smoke, it triggers all the interconnected alarms to sound simultaneously.

Interlinked smoke alarms work by communicating with each other through radio frequency signals or electrical wiring. When one alarm detects smoke or fire, it sends a signal to all the other alarms in the network, causing them to sound an alarm as well.

Interlinked smoke alarms provide an added layer of safety by ensuring that if a fire breaks out in one part of the house, everyone in the home is alerted, even if they are in a different room or on a different floor. This early warning can save lives and give occupants more time to evacuate safely.Studies have shown that interconnected smoke alarms can reduce the risk of fatalities in a house fire by up to 50%. This significant reduction in risk highlights the importance of having an interconnected smoke alarm system in place.
