My Recommendation for Residential Smoke Alarms
Based off a massive amount of research, I believe that every home should only be equipped with a Photo Electric Smoke detector.
The Main Reasons are as follows:
- 51% of Civilian Fire Fatalities Occur between 10PM and 6AM, this indicates that they most often occur while people are sleeping which suggests the likelyhood of a slow smoldering fire. Additionally, when located by the fire department 70% percent of those fatalities were either in the bedroom or trying to escape. Roughly 86% of those who died were from smoke inhalation and assosciated burns.
- Photoelectic detectors detect a smoldering fire on average 30 minutes sooner than an Ionization detector. The failure rate of a Photoelectric detector is about 4% while it is nearly 50% for ionization.
- Ionization detectors are a major source of nuissance alarms. This leads to occupants disabling the device. In 37% of fatality fires the detector was a disabled ionization detector. Photoelectric detectors have a very low propensity for nuissance alarms.
- Due to the nuissance alarms I do not recomend dual detectors. YOU MUST have a working detector. The manufactures will tell you the ionization is better at detecting flaming fires, which is true. However there is a 45 second average difference and most flaming fires occur while being attended to by people ie: cooking fires.
