Effective Home Smoke Detectors
Smoke detectors and smoke alarms have many advantages in homes and now instructed by law on all new construction. Basically, we use the smoke detectors in hotel rooms, and other business homes as well as companies.
Historical Finding: Research from the National Fire Protection Association (NFPA) shows “dramatic declines” in national fire-related deaths and accidents as more US home holds additional smoke detectors and smoke alarms.
- Deaths from house fires dropped nearly 56 percent
- Injuries were down by almost 60 percent
- Four percent of families without smoke detection devices accounted for 31 percent of fires and 40 percent of deaths
- 30 percent of deaths were in homes where smoke detectors had been disabled or inoperable
Today’s Challenge: What sort of Smoke Detector to Install
Research by Underwriters Laboratories (UL) on present causes of home fires discovered that synthetic substances used in home furnishings spark more quickly, burn faster and more significantly, and produce more smoke than natural substances. This fact reduces the time people need to react to an alarm, which makes the rapid reaction to a triggered smoke detector more crucial to escape death or injury.

The Two main things used in the smoke detector:-
- Ionization sensors are more responsive to flaming fires.
- Photoelectric sensors respond to smoldering fires
NFPA recommends installing both kinds of alarms-or a double detector-to maximize protection. Many homes feature a comprehensive alarm system such as a burglar alarm with motion sensors or cameras, smoke detectors, and CO2 detectors. These systems can become pretty fancy and also work with Smartphones, laptops, and tablets!
Fire Department Test Reveals Faster Ionization Detection
- In January 2014, the Lexington, Kentucky Fire Department discussed a smoke alarm test with local TV station WKYT.
- FD staff place a sofa cushion on fire about ten feet away from an ionization sensor, a photoelectric sensor, a double sensor, and a carbon monoxide alarm. They kept the flames low to permit for smoldering.
- Forty seconds following the pillow was lit, the double detector went off. Forty-five seconds later, the ionization sensor triggered, quickly followed by the carbon dioxide detector. The photoelectric alarm went off almost three minutes into the evaluation.
The evaluation was repeated, with the alerts rotated to be closer or further to the flame, but the results remained the same.
While the double detector could be categorized as the “Cadillac” of sensors, a battalion chief observed, “another ionization sensor, which is a step-down and roughly a quarter of the cost [is] just as great.”
Underwriters Laboratories: Smoke Particles Size Makes the Difference
A 2006 study by UL and the NFPAs Fire Protection Research Foundation concluded that ionization and photoelectric smoke detectors are alerted to different smoke particle sizes.
UL’s research found that ionization smoke alarms go off earlier when something unexpectedly bursts into flame. These sorts of fires have smoke particles that are smaller. Ionization detectors also activate sooner for high-energy fires, like those from toasters. Photoelectronic sensors triggered earlier for lower-energy, smoldering fires, which have larger smoke particles.
Current research is looking at the incidence of smoldering versus sudden-burst fires, the shorter timeframes between fire and smoke, and emerging technologies to detect them earlier.
