Q: Types of Smoke Detectors

A: Smoke detectors work differently than portable or fixed gas detectors like the ones on GasDog. Smoke detectors come in several types, each using different technologies to detect smoke and fire. The main types are:

• Ionization Smoke Detectors: These are more responsive to fast-flaming fires. They use a small amount of radioactive material to ionize air, creating an electrical current. When smoke enters, it disrupts the current, triggering the alarm.
• Photoelectric Smoke Detectors: Best for detecting smoldering, slow-burning fires. They use a light beam and sensor inside the unit. When smoke enters, it scatters the light, causing it to hit the sensor and activate the alarm.
• Dual-Sensor Smoke Detectors: These combine both ionization and photoelectric technologies, offering protection against both fast-flaming and smoldering fires.
• Heat Detectors: Unlike smoke detectors, these respond to high temperatures or rapid temperature increases, making them suitable for kitchens or garages where smoke might not indicate a fire.
