FAQs
What kinds of smoke detectors do you supply and install in Cosby?
We specialize in the latest dual-sensor and “smart” smoke detectors. Dual-sensor units combine photoelectric and ionization technology to catch both smoldering and fast-flame fires. Our smart models add Wi-Fi, self-testing, voice alerts, and mobile-app notifications so you receive alarms on your phone even when you are away. All units are UL-listed, comply with the 2018 International Residential Code (IRC) adopted in Tennessee, and include a 10-year sealed lithium battery for maintenance-free power backup.
Are hard-wired or interconnected alarms required by local code in Cosby?
Newly constructed homes in Cosby (Cocke County, TN) must follow the 2018 IRC, which requires smoke alarms to be hard-wired with battery backup and interconnected so that activation of one alarm triggers all others. Remodeling projects that involve bedroom additions or major electrical work must also meet this standard. For existing dwellings, battery-only units are allowed, but we strongly recommend upgrading to interconnected detectors—either wired or wireless—for faster whole-house notification and greater safety.
How often should I test or replace my smoke detectors?
1. Test monthly by pressing the test button until the alarm sounds. 2. Clean the unit with a vacuum brush every six months to remove dust and cobwebs. 3. For sealed 10-year battery models, replace the entire detector at the 10-year mark (the end-of-life chirp will remind you). For models with replaceable 9-volt batteries, change the battery once a year or whenever you hear a low-battery chirp. 4. Regardless of type, replace any detector that fails a test, is physically damaged, or is more than 10 years old.
Can you retrofit my older log cabin or rental property without tearing out walls?
Yes. We offer wireless, interconnected detectors that form a secure RF mesh network, eliminating the need to run new cable through finished walls or historic log structures. The detectors pair in minutes, meet interconnection requirements, and can be combined with hard-wired units if only certain areas lack wiring. Installation is clean, fast, and fully code-compliant.
Do your detectors also monitor carbon monoxide or heat?
Absolutely. We carry combo units that integrate smoke, carbon monoxide (CO), and fixed-temperature heat sensors in one compact device. This is especially important in Cosby’s cabins and homes that use wood stoves, propane heaters, or gas appliances. If a dedicated heat detector is required—for example, in attics or kitchens—we can network those into the same smart system so all alarms sound together.
What does professional installation cost and how long will it take?
Prices vary with the size of the home and the type of detector: • Standard hard-wired dual-sensor: $95–$135 per unit installed. • Smart Wi-Fi dual-sensor: $150–$225 per unit installed. • Wireless interconnect hub (if needed): $75–$110. A typical three-bedroom home needs 5–7 detectors and takes 2–3 hours to complete, including code inspection, testing, and app setup. Larger properties or complex retrofits may take a half day. All installations include a workmanship warranty and documentation for insurance or short-term rental permitting.
