FAQs
What types of smoke detectors does Line of Defense Electrical install in Jellico?
We carry and install photoelectric, ionization, dual-sensor, and smart Wi-Fiâenabled smoke detectors from leading brands. Our technicians will evaluate your home or business and recommend the model that best addresses your layout, wiring, and fire-risk profile.
How often should I replace batteries and the entire smoke detector unit?
Test your alarms monthly and change standard alkaline batteries every six months (lithium batteries are sealed for 10 years). The NFPA and the Tennessee State Fire Marshal recommend replacing the entire detector every 10 years, even if it still chirps during a test, because the sensing elements lose sensitivity over time.
Are your installations compliant with local and national fire-safety codes?
Yes. All installs follow NFPA 72 guidelines, manufacturer specifications, and the current Tennessee Residential Building Code. Because Jellico participates in the state fire-code program, our work is inspected when required and comes with a certificate of compliance for your insurance records.
Can you link new smoke detectors to my existing security or alarm system?
In most cases, yes. We can interconnect 120-volt hard-wired detectors with battery backup, wirelessly pair additional units, or integrate smart detectors into platforms like Ring, Nest, or traditional monitored security panels. During the site visit we check compatibility and provide options before any work begins.
What does installation cost and how long does it take?
A standard hard-wired replacement starts around $85 per device, while new-construction or smart-detector installs range from $110 to $160 each, including materials and programming. A typical three-bedroom home can usually be completed in two to three hours with minimal drywall disturbance.
Do you offer maintenance or inspection services after installation?
Absolutely. We provide annual inspection plans that include functional testing, battery replacement, cleaning, and documentation for landlords or commercial properties. Emergency troubleshooting is available 24/7 to Jellico and surrounding Campbell County communities.
