1 Saving More Lives With Photoelectric Smoke Detectors NEOFPA.ORGMr. Earl Lee Warning
2 Do you know what TYPE of smoke detector you have? Does it Matter?
3 Based on industry information, what have you been told for 30 years?
4 Based on industry information, what have you been told for 30 years? In spite of their differences, either one of the two types of detectors is acceptable for home use.
5 Based on industry information, what have you been told for 30 years? In spite of their differences, either one of the two types of detectors is acceptable for home use.Find the least expensive detector that is UL Listed.
6 Smoke Detector History st battery detectorNIST (National Institute of Standards & Technology) conducted smoke detector testing1980’s - 75% of homes had smoke detectors% of homes had smoke detectors2008 – 96% of homes had smoke detectors,25% of homes do not have a workingsmoke detector
7 There are two TYPES of sensors in smoke detectors: Photoelectric & Ionization
8 IONIZATION: PHOTOELECTRIC: Contains a small amount of radioactivity that conducts electricity. Ionization alarms are more sensitive to the tiny particles of combustion that can’t be seen or smelled, those emitted by FLAMING FIRES.Ionization alarms are MORE PRONE TO FALSE ALARMS from cooking and steam from bathrooms.PHOTOELECTRIC:Contains a beam of light and a photocell within the chamber. Photoelectric alarms are more sensitive to the large particles of combustion emitted by SMOLDERING FIRES.There are 2 types of smoke alarms, Ionization alarms use radioactive material, Photoelectric alarms use a light beam. Dual sensors combine the two technologies. Ions detect flaming fires faster, Photos detect smoldering fires faster. We will look at what this really means. But, did you know the ionization detector was originally designed to detect gases? It is good at detecting very small particles. It was first marketed as a combustion detector. It has an inherent flaw. When smoke travels away from its source it cools, the particles become larger, and the ionization has problems. The photoelectric doesn’t have this problem. It was designed to be a smoke alarm.8
10 Photoelectric smoke detectors are the detector of choice! But why? Here are two tragic examples:
11 Andrea Dennis, Kyle Raulin, Al Schlessman, Erin DeMarco, and Christine WilsonThese five students died atOhio State University onApril 13, 2003 (Palm Sunday)Pictured are Dean and AndreaAndrea died April 13, 2003 in an off-campus housing fire at Ohio State University.She died on a Palm Sunday, at 4:00 in the morning from smoke inhalation.11
12 Julie Turnbull, Kate Welling & Steve Smith died in this house on April 10th, 2005 (Palm Sunday) at Miami UniversityPictured are Doug and Julie.Julie died April 10, 2005 in an off-campus housing fire at Miami University.She died on a Palm Sunday, at 4:00 in the morning from smoke inhalation.12
13 There were more than 20 WORKING ionization smoke detectors in these two fires... And 8 students died!
14 There have been several large studies conducted over the years that have shown that photoelectric technology is superior.
15 The Studies IAFC study-1980 Texas A & M-2 1/2 year study: 1990’s NIST sponsored private industry study-2001NIST study-2008
16 The Results They were consistent… Ionization alarms sounded tens of seconds faster than photoelectric alarms in flaming fires.Photoelectric alarms sounded tens of MINUTES faster in smoldering fires.Ionization smoke detectors failed to sound at all 20% of the time in smoldering fires!
17 Some Fire Service Leader Quotes “If everybody in the country would install these (photoelectric smoke alarms) we would probably save about a thousand lives a year.”AFM Gordon Simpkinson Palo Alto Fire Department Palo Alto, California, USA October, 2010“How many lives have been lost because the public has not been told the truth?”Chief Jay FlemingBoston Fire DepartmentBoston, MAOctober, 2006
18 PR Campaign Chief Marc McGinn Albany Fire Department Albany, California, USA July, 2010
19 NEOFPA & Earl Lee Warning’s Recommendations At a minimum, install a Photoelectric smoke detector on each level of your home, one outside each sleeping area and one inside each bedroom.Consider interconnected photoelectric detectors, either wired or wireless. When one smoke detector activates, all detectors in your home will sound!We will not recommend the placing of ionization smoke detectors in any location. If a resident has ionization smoke detectors
20 What about a combination detector that has both photoelectric & ionization sensors?
21 These are not recommended due to the ionization sensor that will still produce nuisance false alarms. This causes users to remove the batteries rendering the detector useless!
22 What if you have ionization detectors? We recommend that you install a photoelectric detector in each recommended location in your home.Maintain your existing ionization smoke detectors until you replace them.You may choose to install ionization detectors in addition to photoelectric detectors in each recommended location in your home.Smoke detectors need to be replaced when malfunctioning or have reached 10 years of age. Many residents may need to replace their detectors anyway!
29 To Review: Photoelectric Smoke Detectors: Alert tens of minutes faster (Resulting in more escape time, less deaths, injuries & property damage) Less nuisance false alarms (Resulting in less disabled detectors from disconnecting the batteries)
30 What’s the price? Photoelectric-$12 Ionization-$8
