Question 1

What is the difference between a smoke detector and a fire alarm?

Accepted Answer

A smoke detector is a single device that detects smoke particles in the air and sounds an alarm. A fire alarm system is a complete network of devices including smoke detectors, heat detectors, manual pull stations, control panels, and notification devices (horns, strobes) that work together to detect fires and alert building occupants. Smoke detectors can be standalone units or connected to a larger fire alarm system.

Question 2

How often should smoke detectors be replaced?

Accepted Answer

Smoke detectors should be replaced every 10 years, regardless of whether they appear to be working. The sensors degrade over time and become less sensitive to smoke. Check the manufacture date on your detector and replace it when it reaches 10 years old. Test your smoke detectors monthly by pressing the test button.

Question 3

What types of smoke detectors are available?

Accepted Answer

There are three main types: 1) Ionization smoke detectors - best for detecting fast-flaming fires with smaller smoke particles. 2) Photoelectric (optical) smoke detectors - best for detecting slow-smoldering fires with larger smoke particles. 3) Dual-sensor detectors - combine both technologies for comprehensive protection. Most experts recommend photoelectric or dual-sensor types for home use.

Question 4

Where should smoke detectors be installed?

Accepted Answer

Install smoke detectors on every level of your building, inside each bedroom, and outside sleeping areas. Mount them on the ceiling or high on the wall (within 12 inches of the ceiling). Avoid installing near kitchens (at least 10 feet away), bathrooms, or areas with high humidity to prevent false alarms. Follow local building codes for specific requirements.

Question 5

Why does my smoke detector keep beeping?

Accepted Answer

Intermittent beeping usually indicates a low battery that needs replacement. Other causes include: dust accumulation in the sensor chamber, high humidity, temperature fluctuations, or the detector reaching end of life. Clean the detector with compressed air, replace the battery, and if beeping continues, replace the entire unit.

Question 6

Can smoke detectors detect carbon monoxide?

Accepted Answer

Standard smoke detectors cannot detect carbon monoxide (CO). You need a dedicated CO detector or a combination smoke/CO detector. Carbon monoxide is an odorless, colorless gas produced by incomplete combustion of fuels. Many modern combination detectors include both smoke and CO detection in a single unit.
