FAQs
What kinds of smoke detectors does Tellico Plains code require in residential properties?
Tellico Plains follows the 2021 International Residential Code (IRC) and NFPA 72, adopted by the State of Tennessee. These standards allow either photo-electric, ionization, or dual-sensor smoke alarms, but they must be UL-listed. New construction and significant remodels must use 120-volt, hard-wired units with battery backup and interconnection, so that when one sounds they all do. Battery-only devices are accepted in existing dwellings that are not undergoing electrical work, provided they are kept in good working order.
Where should smoke detectors be installed to comply with local safety standards?
NFPA 72 and the Tennessee Residential Building Code require smoke alarms: • inside every bedroom, sleeping room, or guest room • outside each sleeping area within 21 ft (typically the hallway) • on every level of the home, including basements and finished attics • at the bottom of split-level landings if the level without a bedroom is less than one full story up or down • at least 4 in from walls when ceiling-mounted, or 4–12 in from the ceiling when wall-mounted • away from HVAC supply vents, windows, and bathrooms with showers to avoid nuisance alarms. Garages are exempt for smoke alarms but require a heat detector if the home is wired for whole-home interconnection.
How often should I test, clean, and replace my smoke detectors?
• Test each alarm monthly using the test button until it sounds. • Gently vacuum the detector twice a year to remove dust that can cause false alarms or delayed detection. • Replace alkaline batteries once a year (or immediately when the unit chirps). For 10-year sealed-battery models, replace the entire unit when it chirps. • Regardless of type, replace the entire alarm every 10 years from the manufacture date printed on the back; the sensing chamber loses sensitivity over time. • After any significant electrical surge (e.g., lightning strike), test the units again and replace if they fail.
Are interconnected smoke alarms mandatory in Tellico Plains?
Yes. For homes built or substantially renovated after July 1, 2012, Tennessee Building Code Section R314.4 mandates interconnection—hard-wired or wireless—so that activation of one alarm triggers all others. Interconnectivity may be wired through a dedicated 15-amp circuit or via RF-linked alarms listed for multi-station interconnection if wiring modifications are impractical, such as in historical homes undergoing limited alterations.
Do I need a combination carbon-monoxide/smoke alarm if I have gas appliances or an attached garage?
Yes. Tennessee Code 68-102-159 requires carbon-monoxide protection in any dwelling that has fuel-burning appliances, fireplaces, or an attached garage. You may install separate CO alarms or a UL-217/UL-2034 listed combination smoke/CO unit. Combination devices must meet the same placement rules as smoke alarms, but at least one CO sensor must be on each level and outside every sleeping area. Hard-wired combination alarms with battery backup are preferred for new construction.
How can I be sure my smoke-alarm installation will pass the electrical inspection in Monroe County?
1. Pull the correct electrical permit with the Monroe County Building & Codes Department before beginning work. 2. Use UL-listed alarms and follow the manufacturer’s instructions plus NFPA 72 spacing rules. 3. For hard-wired units, run 14-2 with yellow 14-3 interconnect cable on a dedicated circuit or tie into a general lighting circuit protected by AFCI breakers (2017 NEC 210.12). 4. Install the alarms no earlier than drywall trim-out to avoid dust contamination but before the final inspection. 5. Perform a functional test of every unit, verify interconnection, and label the breaker. 6. Keep product manuals and the dated receipt on site for the inspector. If you are unsure, hire a Tennessee-licensed electrical contractor experienced in NFPA 72 installations in Tellico Plains.
