Smoke Alarm Installer Training
Please Introduce Yourself Name Organization
Course Objectives § Recognize the need for smoke alarms. § Describe the selection of single-station smoke alarms. § Differentiate between the smoke-sensing technologies of single-station smoke alarms.
Course Objectives § Determine the minimum number of smoke alarms needed to meet the requirements of NFPA® 72 for residential structures and HUD guidelines for mobile homes. . § Describe installation of alert devices for people with disabilities. § Recognize the opportunity to conduct fire and life safety education during smoke alarm installation.
Modern furnishings and construction materials make smoke alarms vital to resident safety. [Click to play video. ]
Smoke alarms alert residents to smoke and awaken sleeping residents. • Open floor plans do little to reduce spread • Modern furnishings burn faster, release gases Smoke spreads quickly Fatal fires occur while occupants sleep • Alarms alert occupants to smoke • Wake sleeping residents • Ensures appropriate placement • Opportunity for fire and life safety education Alarms most effective when installed by trained personnel
Ensure alarms are approved by a nationally-recognized testing authority.
Single station smoke alarms are suited for residential installation. • With many alarms, activation of one does not activate all • Require battery, replacement • Require maintenance • Relatively inexpensive • Use same technology as hard-wired alarms • Easy to install • Do not require licensed electrician to install
Ionization alarms are good at detecting fast flaming fires with little visible smoke. Ionization smoke alarms react to ionized molecules in the chamber.
Photoelectric alarms are more responsive to smoldering fires and dense smoke. A refractory smoke alarm detects smoke when light reaches a sensor after reflecting off smoke.
Combination ionization/photoelectric alarms combine the benefits of both technologies. Alarm can be activated by either of the sensors within the unit.
Several smoke alarms are available through the Oklahoma Assistive Technology Foundation program. Ionization/ Photoelectric 9 V front loading battery Test button Hush feature 10 -year life Kidde PI 9000
Several smoke alarms are available through the Oklahoma Assistive Technology Foundation program. Photoelectric Sealed lithium battery Automatic activation once the alarm is installed Test/Hush button for testing Kidde P 3010 L Alarm
Several smoke alarms are available through the Oklahoma Assistive Technology Foundation program. Photoelectric Plugs into wall outlet Lithium Battery included. 90 db alarm 177 candela strobe light Gentex Series 7139 LS
What are the two common smoke Review Questions sensing technologies used in single-station alarms? Which technology is most prone to false alarms from cooking? Which technology is best at detecting smoldering fires and dense smoke? Which technology is best at detecting fast flaming fires with little smoke? Which technology is most prone to false alarms from dust and insects?
Smoke alarm placement influences their effectiveness. Warning device Alert sleeping residents Only a few minutes to escape Install where smoke will travel Smoke rises Path of least resistance Limited device life Replace every ten years Note replacement date on back of alarm
NFPA® 72 lists requirements for smoke alarm placement in existing homes. One alarm on every level One alarm in every sleeping room One alarm in each hallway

Install alarms in air flow areas near the ceiling where smoke will travel.
Install alarms in air flow areas near the ceiling where smoke will travel.
Review Questions What are the minimum smoke alarm requirements in existing residential construction? In mobile homes? How far should wall-mounted smoke alarms be placed from the ceiling? Where should smoke alarms be placed on a sloped ceiling, relative to the peak?
False alarms are more than an annoyance. Annoying noise Assume all alarms are false Disconnect battery or remove alarm to silence false alarms
Avoid these sources of false alarms. More than 12 inches from More than 3 feet from More than 10 feet from Kitchen doorway Bathroom doorway Fluorescent lights Stove Damp, humid, steamy areas Forced air vents Ventilation fans Bathrooms with showers Unheated buildings Furnace Water heater Air conditioner units Ceiling fans More than 20 feet from Not in areas below 40°F (4°C) or above 100°F (38°C) Outdoor rooms, porches Space heater Wall heater Unfinished attics, basements
Remember these placement guidelines. Use your best judgment Install the number of alarms needed Write the replacement date on the alarm Do not remove existing alarms
Learning Activity Identify the smoke alarms needed for residential structures and mobile homes.
