Smoke and CO Detector Installation in Southern NH and the Merrimack Valley
Hardwired, interconnected smoke and carbon monoxide alarms placed and wired to code.
What you get
Detection that wakes the whole house
Hardwired, interconnected smoke and carbon monoxide alarms are the ones that wake the whole house, because when one senses trouble, they all sound. We install and wire smoke and CO detectors to code, place them where they belong, and interconnect them with battery backup, so your family gets the earliest possible warning. The estimate is free.
A single battery alarm chirping in a hallway is not the same as a hardwired, interconnected system. Interconnected alarms all sound together the instant any one of them detects smoke or carbon monoxide, which buys the minutes that matter, especially at night and in a multi-level home. Code sets where alarms go, in every bedroom, outside each sleeping area, and on every level, and calls for battery backup so they still work in an outage. We place and wire them to that standard so the coverage is complete, not piecemeal.
Plan the coverage
We map where alarms are required and where yours are missing or out of date, then give you a clear written number before any work starts.
Wire and interconnect
We install hardwired smoke and CO alarms with battery backup, interconnect them so one triggers all, and place each one where code and safety call for it.
Test the whole system
We test every alarm and the interconnection, confirm they all sound together, and show you how to check and maintain them.

Get a Free EstimateWhere are smoke and carbon monoxide detectors required?
Code calls for a smoke alarm in every bedroom, outside each sleeping area, and on every level of the home, including the basement, and carbon monoxide alarms outside sleeping areas and on each level. We place yours to meet that standard so no part of the house is uncovered.
What does interconnected mean, and why does it matter?
Interconnected means all the alarms are linked, so when one senses smoke or carbon monoxide, every alarm in the house sounds at once. That matters most at night, when a fire in the basement needs to wake someone sleeping upstairs. It is the difference-maker that a single standalone alarm cannot provide.
Do hardwired alarms still work in a power outage?
Yes. Hardwired alarms are required to have battery backup, so they keep protecting you when the power is out. We install them with that backup and show you how to keep the batteries current.
How often should smoke and CO detectors be replaced?
Smoke alarms are generally replaced about every ten years and CO alarms about every five to seven, because the sensors wear out even when the unit still chirps. If yours are older or you are not sure of their age, we can tell you and replace what is due.
