If you’re searching for Tyco Integrated Security, you’re looking at a brand that no longer exists. It was absorbed into Johnson Controls through a $16.5 billion “merger” in 2016 — one of the largest corporate reshuffles in security industry history.
Here’s the full timeline of what happened, where Tyco’s security services ended up, and what you should actually buy in 2026 — whether you’re a former Tyco commercial customer or a homeowner who stumbled on the name.
The Complete Tyco Timeline: 1960-2026
| Year | Event | What It Meant |
|---|---|---|
| 1960 | Tyco founded as investment holding company | Started in experimental science, not security |
| 1997 | Tyco acquires ADT for $6.7B | Enters the security industry through acquisition |
| 2002 | CEO Dennis Kozlowski arrested for fraud | $600M corporate scandal, stock crashed 80% |
| 2007 | Tyco splits into 3 companies | Tyco International keeps fire & security division |
| 2012 | Tyco spins off ADT as separate public company | ADT becomes independent (residential). Tyco keeps commercial = “Tyco Integrated Security” |
| 2012-2016 | Tyco Integrated Security operates independently | Commercial-only: hospitals, banks, schools, government, enterprise |
| 2016 | Johnson Controls “merges” with Tyco ($16.5B) | Tax inversion deal — JCI moved HQ to Ireland for tax benefits. Tyco brand begins phase-out |
| 2018 | Johnson Controls sells residential power solutions | Focuses on commercial building technology |
| 2019-2026 | Tyco brand fully absorbed into JCI | “Tyco” name only survives on legacy equipment and fire panels |
Where Did Tyco’s Security Services Go?
When Tyco ceased to exist as a standalone brand, its services scattered across three different companies:
| Tyco Division | Where It Went | What They Do Now |
|---|---|---|
| Residential security | ADT (spun off 2012) | Still the largest residential security provider in the US with 6M+ customers |
| Commercial security | Johnson Controls | Enterprise building management, access control, fire systems for large facilities |
| Fire protection | Johnson Controls (Tyco Fire Protection Products) | Fire suppression, sprinklers, alarms — still uses “Tyco” name on some fire products |
| Monitoring centers | Johnson Controls / ADT | Split between commercial (JCI) and residential (ADT) |
What This Means for Former Tyco Commercial Customers
If your business had a Tyco Integrated Security system, you’re now a Johnson Controls customer — whether you knew it or not. Here’s what to know:
| Situation | What Happened | What to Do |
|---|---|---|
| Active Tyco contract | Transferred to Johnson Controls | Contact JCI at 1-800-315-5734 to verify your account |
| Tyco fire panels | Still supported under JCI | JCI services Tyco fire equipment — get quotes for maintenance |
| Tyco access control | Now JCI C-CURE/Kantech | Consider upgrading to modern cloud-based access control |
| Expired contract | You’re month-to-month or free | Get competitive quotes — you have leverage |
| Want to switch | No loyalty obligation to JCI | Modern alternatives below are often cheaper and better |
Warning: The Tyco/JCI Contract Trap
When contracts transferred from Tyco to Johnson Controls, many businesses didn’t realize they were automatically renewed under JCI terms. If you’re a former Tyco customer, check:
- Whether your contract auto-renewed (and for how long)
- Your current monthly rate vs. market rates
- Early termination fees before switching
- Whether your equipment is owned or leased
Many former Tyco customers are paying 30-50% above market rates simply because the contract rolled over and nobody questioned it. Our contract cancellation guide walks through how to exit.
For Homeowners: Tyco Was Never for You
Tyco Integrated Security was 100% commercial. They never sold residential security systems. If you’re a homeowner looking for home security, you’ve come to the right place — but Tyco isn’t the answer.
Here’s what actually makes sense for home security in 2026:
| System | Best For | Monthly Cost | 3-Year Cost | Contract | Rating |
|---|---|---|---|---|---|
| Abode | Smart home + Apple HomeKit | $0-20/mo | $199-919 | None | 4.5/5 |
| Ring | Budget + Alexa ecosystem | $0-20/mo | $200-920 | None | 4/5 |
| SimpliSafe | Simple DIY | $0-28/mo | $250-1,258 | None | 4/5 |
| ADT | Name brand + pro install | $6-60/mo | $416-2,360 | 0-36 mo | 3.5/5 |
Abode is our top recommendation for homeowners — it’s the only system that works with Apple HomeKit, supports Z-Wave/Zigbee/Matter devices, and offers professional monitoring from $6/month with absolutely no contracts. It’s what Tyco would have been if they’d cared about residential customers and modern technology.
For Businesses: Modern Alternatives to Johnson Controls
If you’re a business still running Tyco/JCI equipment, here are your options:
| Need | JCI/Tyco Legacy | Modern Alternative | Advantage |
|---|---|---|---|
| Access control | C-CURE / Kantech | Verkada, Openpath, Kisi | Cloud-based, mobile credentials, no server needed |
| Video surveillance | Tyco Illustra cameras | Verkada, Rhombus, Meraki | Cloud management, AI analytics, no NVR |
| Intrusion detection | DSC / Bentel panels | Alarm.com commercial, Honeywell Pro | Remote management, mobile app, cloud monitoring |
| Fire & life safety | Tyco/Simplex/Autocall | Still JCI or Honeywell | Fire panels are harder to replace — JCI service may be your best bet |
| Monitoring | JCI monitoring center | Any UL-listed central station | Competitive bids can save 20-40% |
The Tyco-ADT Connection: Why It’s Confusing
People often confuse Tyco and ADT because they were the same company for 15 years (1997-2012). Here’s the simplified family tree:
- 1997: Tyco buys ADT — ADT becomes Tyco’s residential security arm
- 2012: Tyco spins off ADT as independent company — ADT gets residential, Tyco keeps commercial
- 2016: Johnson Controls absorbs Tyco — the Tyco brand effectively dies
- 2026: ADT still exists independently (6M+ customers). Tyco is just a name on old fire panels.
So if you want what Tyco’s residential division became: that’s ADT. But we’d recommend Abode or Ring over ADT for most homeowners — lower cost, no contracts, better technology.
The $16.5 Billion Tax Dodge
The Johnson Controls-Tyco “merger” was controversial. While marketed as a strategic combination, it was widely recognized as a tax inversion — Johnson Controls (Milwaukee, WI) effectively moved its headquarters to Ireland (where Tyco was incorporated) to reduce its US tax bill. Key facts:
- JCI estimated annual tax savings of $150M+
- Drew criticism from then-President Obama and Congress
- The 2017 Tax Cuts and Jobs Act reduced some inversion benefits, but the Ireland HQ remains
- JCI’s effective tax rate dropped from ~25% to ~14% post-merger
This matters for customers because the merger was financially motivated, not operationally. Tyco customers didn’t get better service — they got absorbed into a larger bureaucracy optimized for tax efficiency.
Frequently Asked Questions
Is Tyco Integrated Security still in business?
No. Tyco was acquired by Johnson Controls in 2016 and the brand was phased out. Your account, if active, is now under Johnson Controls. Contact JCI at 1-800-315-5734.
Is Tyco the same as ADT?
They were from 1997-2012. Tyco bought ADT in 1997, then spun it off as an independent company in 2012. ADT handles residential security. Tyco (now Johnson Controls) handled commercial. They’ve been separate companies for over a decade.
Can I still get Tyco fire panels serviced?
Yes — Johnson Controls still manufactures and services Tyco, Simplex, and Autocall fire panels. Contact JCI for service. These are the only products that still carry the Tyco name.
Should I switch from Johnson Controls to a DIY system?
For homes: absolutely. JCI doesn’t even offer residential service. Get Abode, Ring, or SimpliSafe. For small businesses: possibly — cloud-based systems like Alarm.com commercial or Verkada can replace legacy Tyco equipment at lower cost. For large enterprises: JCI may still be your best option for integrated building management.
What happened to my Tyco warranty?
Equipment warranties transferred to Johnson Controls. If you have active Tyco equipment under warranty, JCI is responsible for honoring it. Get everything in writing — some customers have reported difficulty claiming legacy Tyco warranties.
Is Johnson Controls any good?
For large commercial buildings (hospitals, campuses, high-rises) — yes, they’re a major player with legitimate capabilities. For small businesses or homes — they’re overkill, overpriced, and there are much better options available. Don’t use a Fortune 500 enterprise vendor for a $200/month security need.
Growing up with Law and Order and CSI shows taught Isabelle Landau one thing: if people back then had high-quality home security systems, those series would have been way shorter. In our modern world, technology helps us keep burglars away easily, and this is what Izzy studies and writes about: alarm systems, home security, protection systems, and more.

Also as a customer one time I called customer support and it took 30+ minutes before speaking with someone!
Previous Employee says
Worked for them for 10 yrs. Best worldwide presence even best domestic presence for install and service: unfortunately techs aren’t.trained on IP technology and can’t keep up with emerging technology. Stiill the best and most reliable in markets without a competent local competitor
Brad says
I thought it was just me but man I have had such a hard time getting information from them. Heck, even getting in touch was a struggle. I still have not decided on going with Tyco or not. Seeing as it took this much effort to find basic information, I would hate to think what would happen if I ran into issues and couldn’t reach them.
Jack M. says
Out of all the companies I have been researching, Tyco seems to be coming out on top. They don’t have all the whistles and bells of many other larger branded companies but they make having a security system easy.
David R. says
Yup! They are not about flashy stuff but what they do offer is a lot of options. I love how they have something for everyone be it basic home security or more advanced surveillance. I spent many years with one of the biggest companies in the US and switching to Tyco was the best choice I ever made.
Kevin M. says
I never heard of this company prior to signing with them. It has only been a few months but thus far it has been pretty good. My wife likes the company because they have been patient with her and all her concerns and questions. I like it for the fair price and reliability. Great review!
Martin Roberts says
What services did you get, if you don’t mind me asking? I am trying to find a specific set up. My main issues have to do with some crazy neighbors as well as animals. I want to make sure I can get some security for my home and my family. I want to make sure we can come and go safely from the house. They know the local cops so they do nothing for us.
Vince Dean says
Tyco is one of those places that not many people talk about online and I think it is because of their own online presence. I was talking to someone with the company and they felt very misplaced like they didn’t even know what they offered so I decided to go with another company.
Jacob Stone says
I agree with this. I feel like if they changed to a more modern aspect they would gain more solid recommendations and reviews. I was with the company for 3 years before I ended up moving. I opted for my own security set up this time around but I recommend them 10 fold.
