A smoke alarm is a critical safety device designed to detect smoke and alert occupants of a potential fire. These devices have saved countless lives by providing early warnings that allow people to evacuate before a fire spreads. Whether installed in homes, offices, or industrial buildings, smoke alarms are essential for fire prevention and safety compliance.

How Smoke Alarms Work
Smoke alarms use sensors to detect smoke particles in the air and trigger an alarm when certain thresholds are met. There are two main types of smoke detection technologies:

Ionization Smoke Alarms

Best at detecting fast-flaming fires.

Uses a small amount of radioactive material to ionize air, triggering an alarm when smoke disrupts the ion flow.

Photoelectric Smoke Alarms

More effective at detecting slow, smoldering fires.

Uses a light beam that is scattered by smoke particles, activating the alarm.

Key Features of Smoke Alarms
Loud Alarm Sound – Alerts occupants to smoke presence.

Battery or Hardwired Power Supply – Battery-operated alarms provide flexibility, while hardwired ones offer reliability with backup power.

Interconnectivity – Some alarms are connected so that when one is triggered, all alarms sound.

Smart Features – Advanced models offer Wi-Fi connectivity and mobile alerts.
