Why Hardwired Interconnected Detectors
All Alarms Sound Together
Interconnected detectors trigger every alarm in the home when one senses smoke — critical for waking sleepers in distant bedrooms before smoke reaches them.
Reliable Power
Hardwired detectors run on home power with battery backup, so they don't fail because of a dead battery you forgot to replace — the leading cause of non-functioning detectors.
Meets Current Code
Hardwired, interconnected detectors are required by code in new and remodeled homes, and expected by inspectors, insurers, and buyers.
Our Smoke Detector Process
Coverage Plan
We map detector placement to code — every bedroom, outside sleeping areas, and one per level, including basements and hallways.
Wire & Interconnect
We run interconnect wiring between detectors and connect to a constant-power circuit with battery backup.
Install & Test
We mount detectors, test interconnection so all sound together, and verify battery backup.
Document & Educate
We document placement for inspection and walk you through testing, battery replacement, and the 10-year replacement rule.
Smoke Detector Questions
Q.Where are smoke detectors required?
Current code requires a smoke detector in every bedroom, outside each sleeping area, and on every level of the home including basements. We map the exact placement to your home during the consult.
Q.Why do they need to be interconnected?
When detectors are interconnected, any one sensing smoke triggers all of them to sound — so a fire in the basement wakes a sleeper in an upstairs bedroom. This is a life-safety requirement of current code.
Q.How often should smoke detectors be replaced?
Smoke detectors should be replaced every 10 years — the sensors degrade over time even if they still test fine. We replace aging units and document the install date so you know when they're due.
Q.Can you add detectors without rewiring the whole house?
Often yes. We can interconnect new hardwired detectors to an existing circuit, or install wireless-interconnected detectors where fishing wire isn't practical — both meet code for interconnection.
