What type of smoke detector is suitable for kitchens to reduce false alarms?

• A. Photoelectric smoke detectors
• B. Ionic smoke detectors
• C. Heat detectors
• D. Combination smoke detectors

Answer: (A)

In kitchens, where cooking activities can produce steam, smoke, and other particles that might trigger a false alarm, photoelectric smoke detectors are particularly suitable because they are less sensitive to these types of particles. They use a light beam that is scattered by smoke, detecting smoke particles more effectively and accurately in environments where nuisance alarms are a concern. This characteristic makes photoelectric detectors preferable for kitchen use compared to ionization smoke detectors, which can be more prone to react to cooking smoke. Heat detectors are also a viable option as they respond to temperature changes rather than smoke, but they may not detect smoldering or flaming fires until it's too late. Combination smoke detectors, while versatile, may not specifically filter out kitchen-related false alarms as effectively as photoelectric models do.
