Understanding Different Sensor Technologies
Fire alarm detectors employ various sensor technologies, each with its own strengths and weaknesses. Understanding these differences is crucial for choosing the right type of detector for your specific needs and environment. The two primary sensor types used in smoke detectors are ionization and photoelectric, while carbon monoxide detectors primarily use electrochemical sensors.
Ionization smoke detectors are generally more responsive to fast-flaming fires, such as those involving paper or flammable liquids. They contain a small amount of radioactive material that ionizes the air within the detection chamber. When smoke enters the chamber, it disrupts the ionization, triggering the alarm. However, ionization detectors are more prone to false alarms from cooking smoke or steam.
Photoelectric smoke detectors, on the other hand, are more sensitive to slow-smoldering fires, such as those involving upholstered furniture or electrical wiring. They use a light source and a photocell. When smoke enters the chamber, it scatters the light, and some of the light hits the photocell, triggering the alarm. Photoelectric detectors are generally less prone to false alarms from cooking smoke or steam compared to ionization detectors.
Carbon monoxide detectors use electrochemical sensors to detect the presence of CO gas. These sensors contain a chemical substance that reacts with CO, generating an electrical current that triggers the alarm when the CO level reaches a dangerous threshold. CO detectors are designed to be highly specific to carbon monoxide and less susceptible to false alarms from other gases.
Dual-sensor detectors combine both ionization and photoelectric sensors in a single unit. These detectors aim to provide comprehensive protection against both fast-flaming and slow-smoldering fires, offering a balance of sensitivity and reduced false alarm rates.

As a general rule, smoke detectors should be installed on every level of your home, including the basement. They should also be placed inside each bedroom and outside of sleeping areas. Within bedrooms, detectors should be mounted on the ceiling or high on a wall, as smoke rises. Outside of sleeping areas, detectors should be placed in hallways and living rooms.
Avoid placing smoke detectors near kitchens or bathrooms, as cooking smoke and steam can trigger false alarms. Similarly, avoid placing them near windows or doors, as drafts can interfere with their ability to detect smoke. Keep detectors at least 10 feet away from cooking appliances and humid areas.
Carbon monoxide detectors should also be installed on every level of your home, particularly near sleeping areas. CO is slightly lighter than air and tends to mix evenly throughout a room, so placement is less critical than with smoke detectors. However, it is still recommended to install CO detectors on the ceiling or high on a wall for optimal detection.
For multi-story homes, consider interconnecting your fire alarm detectors. Interconnected detectors communicate with each other, so if one detector detects smoke or carbon monoxide, all the detectors in the house will sound an alarm. This provides early warning throughout the entire home, even if the fire originates in a remote area. Proper placement, combined with interconnected detectors, creates a robust safety net for your home and family.
Understanding Codes and Regulations
Building codes and regulations play a crucial role in ensuring fire safety and the proper installation of fire alarm detectors.
