Understanding Electrical Smoke Detectors

Electrical smoke detectors are life-safety devices that continuously monitor the air for combustion byproducts and provide an early warning of fire. They are powered by the building’s electrical system and, in most modern configurations, contain a backup battery to keep the device operational during a power outage. Because they are hard-wired, they can be interconnected so that when one unit senses smoke, every alarm in the structure sounds simultaneously.

Core Components

• Sensing chamber
• Electronic circuitry
• Audible alarm horn
• Indicator lights
• Interconnect wiring or wireless module
• Backup battery compartment

Detection Technologies

There are two primary sensing methods:

1. Ionization technology uses a small amount of radioactive material to ionize the air inside a chamber. When smoke particles enter, the ion flow is disrupted, triggering the alarm.
2. Photoelectric technology employs a light source and photodiode. Smoke scatters the light onto the sensor, activating the alarm.

Dual-sensor models combine both methods to maximize detection speed for a wide range of fire types.
