FAQs
How often should my smoke detectors be replaced or upgraded in Loudon?
Both NFPA 72 and the Tennessee State Fire Marshal recommend replacing every smoke detector at least once every 10 years, even if it still seems to work. Sensor chambers lose sensitivity over time and newer models offer better photoelectric/ionization or dual-sensor technology. During a service call we check the manufacture date on the back of each unit. If it’s close to—or past—its 10-year mark, we’ll recommend a replacement and can handle the change-out on the spot.
What kinds of smoke detectors do you install and which one is right for my home or business?
We carry three main categories: (1) hard-wired 120-volt with battery backup, (2) battery-only stand-alone units, and (3) smart or interconnected alarms that communicate wirelessly or through the existing wiring. For most Loudon residences we recommend hard-wired, interconnected detectors so that when one alarm sounds, they all sound. In high-ceiling areas, we often install smart detectors with app alerts. Commercial customers usually need addressable or system-monitored detectors tied into a fire-alarm panel to meet code.
Can you interconnect my existing smoke alarms or add smart functionality without rewiring the whole house?
Yes. If your home already has 120-volt wiring between alarms, we can upgrade each unit to an interconnected model in minutes. If wiring is not present, we can install wireless interconnect detectors that sync automatically. For homeowners who want mobile notifications, we can retrofit battery-powered smart modules or replace selected units with Wi-Fi alarms so you get alerts on your phone whenever an alarm or low-battery condition occurs.
Do your installations meet Loudon County, Tennessee, and NFPA code requirements?
Absolutely. Our licensed electricians follow NFPA 72, the 2018 IRC/IBC as adopted by Tennessee, and all Loudon County amendments. That means installing alarms in every bedroom, outside each sleeping area, and on every level—including basements and finished attics. We also handle the permit process when required, perform a final functional test, and provide documentation for insurance or occupancy inspections.
Are battery-only smoke detectors still legal, or do I need hard-wired units?
Battery-only detectors are legal in existing single-family homes built before hard-wiring became mandatory, but any new construction or major remodel in Loudon must include 120-volt, battery-backup alarms. Even in older homes, we strongly recommend hard-wired or wireless-interconnect units for faster warning. We’ll evaluate your property, explain code obligations, and give you the cost difference so you can make an informed decision.
What should I expect during a smoke-detector service appointment?
Most visits take 60–90 minutes for a typical three-bedroom home. We begin with a free safety audit, checking placement, age, and wiring. We then vacuum and test each sensor with canned smoke, replace batteries, and note any deficiencies. If new units are needed, we install, label, and date them, sync wireless networks if applicable, and demonstrate the test function. Before leaving, we clean up all packaging and provide a written report with maintenance tips and reminder dates for annual tests and future replacement.
