Fire Alarm Companies in CT — How to Choose a Licensed Installer

If you're searching for fire alarm companies in CT, the most important thing to know upfront is this — not every company offering fire alarm services in Connecticut is licensed to do the work. Connecticut requires a specific electrical license to install, service, and inspect fire alarm systems, and working with an unlicensed installer puts your property, your occupants, and your insurance coverage at risk.



Here's what to look for before you hire.


Connecticut Requires a License for Fire Alarm Work

Fire alarm installation and inspection in Connecticut falls under the jurisdiction of the Department of Consumer Protection. Companies performing this work must hold a valid Connecticut electrical contractor license — and the specific license classification must cover fire alarm systems.


DetectionTech holds Connecticut electrical license ELC.0206709-C5 — publicly verifiable through the Connecticut Department of Consumer Protection. We install, service, and inspect fire alarm systems for residential and commercial properties across all eight Connecticut counties.


When evaluating fire alarm companies in CT, ask for the license number and verify it before signing anything. If a company can't provide it, walk away.


What Licensed Fire Alarm Companies in CT Should Offer

A fully licensed fire alarm company in Connecticut should be able to handle:

Installation — new fire alarm system installation for residential, commercial, and industrial properties in accordance with NFPA 72 and Connecticut state requirements. This includes smoke detectors, heat detectors, carbon monoxide detectors, pull stations, notification devices, and fire alarm control panels.


Inspection — annual NFPA 72 fire alarm inspection and testing, producing a formal compliance report that documents the condition of every component. Connecticut requires annual inspection for virtually all commercial properties with fire alarm systems.


Service and repair — troubleshooting and repairing existing systems, replacing degraded or damaged devices, and bringing non-compliant systems back up to code.


Monitoring — connecting fire alarm systems to 24/7 professional monitoring so emergency services are notified immediately when an alarm triggers.

If a fire alarm company in CT can't offer all four of these services under one roof, you'll end up coordinating between multiple vendors — which creates gaps in accountability and compliance.


The Risk of Hiring Unlicensed Fire Alarm Companies in CT

DetectionTech has been called in more than once to fix work done by unlicensed installers. What we typically find — wrong equipment, improper device placement, panels wired incorrectly, and no compliance documentation. In one case the previous installer had used non-UL listed equipment that would never pass an inspection.


The consequences of unlicensed fire alarm work go beyond a failed inspection. If a fire occurs and your system fails because it was improperly installed, your insurance carrier may deny the claim. If an inspector finds unlicensed work, you may face fines and be required to remove and replace the entire system at your own cost.


Skilled work isn't cheap — but cheap work isn't skilled. The difference matters when lives and property are at stake.


What to Ask Fire Alarm Companies in CT Before You Hire

  • What is your Connecticut electrical license number?

  • Are you licensed specifically for fire alarm installation and inspection?

  • Do you provide NFPA 72 compliance reports after inspection?

  • Can you handle repairs and replacements found during inspection?

  • Are you locally based or routing service calls through a national dispatch?


DetectionTech answers yes to all of the above. We're a local Connecticut company with over 20 years of experience installing and inspecting fire alarm systems for homes, restaurants, commercial buildings, multifamily properties, schools, churches, and industrial facilities across all eight CT counties.
