If you’ve ever wondered why your neighbor’s house had fire trucks show up at 3 a.m. even though nobody was home, the answer is almost always the same: they have a monitored fire alarm system.
After installing thousands of these systems across Pearland, League City, Katy, The Woodlands, and greater Houston over the last few years, I still get the same question every single week:
“Mike, what exactly is a monitored fire alarm, and why do I actually need one?”
Let me break it down for you the same way I explain it to every homeowner and business owner who sits across from me at their kitchen table.
How a Monitored Fire Alarm System Actually Works (Step by Step)
- A smoke, heat, or carbon-monoxide sensor detects danger
- The alarm panel instantly sends a digital signal (cellular + phone line or radio backup)
- A UL-listed, Five-Diamond certified central monitoring station receives the signal in under 8 seconds
- Trained operators verify the alarm and immediately call you
- At the exact same time, they dispatch the Houston Fire Department with your address, gate code, and pet locations
- Average HFD notification time: 30–60 seconds from detection
That’s it. No one has to hear a siren. No one has to wake up and call 911. The system does everything automatically—even if the power has been out for three days after a hurricane.

Monitored vs Non-Monitored vs Self-Monitored – The Real Differences
| Type | Who Gets Notified? | Works When You’re Asleep/Vacation? | Works When Power & Wi-Fi Are Out? | Houston Fire Dept Dispatched Automatically? |
| Regular smoke detector | Only people in the house | No | No | No |
| Self-monitored (Ring, SimpliSafe, etc.) | Only your phone | Only if the phone has a signal & battery | Usually dies after 12–24 hrs | No |
| Professionally monitored (what we install) | Central station + you + HFD | Yes | Yes (cellular + 72 hr battery) | Yes – in under 60 seconds |
That last row is why insurance companies and fire marshals love us.
What Is a Supervised Fire Alarm System?
“Supervised” is the technical term the City of Houston and NFPA 72 use. It means every wire, sensor, and battery is constantly checked 24/7. If someone cuts a wire or a battery goes low, the central station gets a trouble signal immediately—not when the fire starts.
Every commercial building in Houston with sprinklers must be supervised. Most homeowners never knew they could (and should) have the same level of protection.
What Is a Centrally Monitored Fire Alarm?
Same thing as “professionally monitored.” The alarm goes to a real central station staffed by live operators (not an app). ADT’s monitoring centers we use are Five-Diamond certified—the highest rating in the industry.
Why Houston Homes and Businesses Need Monitored Fire Alarms More Than Ever
- Houston Fire Department responded to 6,847 structure fires in 2024
- 62 % happened when no one was home or everyone was asleep (Texas Fire Marshal data)
- Average response time without monitoring: 8–11 minutes in many suburbs
- With monitoring: under 60 seconds
- Many insurance companies now give 10–20 % discounts for monitored systems
I’ve personally seen monitored systems save multiple homes in Kingwood after the 2023 attic fires and in Meyerland when electrical panels caught fire during the summer heat waves.
When Is Fire Alarm Monitoring Actually Required in Houston?
Short answer: almost every commercial property and any building with fire sprinklers.

Wireless Monitored Fire Alarms – The Houston Homeowner’s Best Friend
Trying to run new fire-rated cable through a 1960s ranch or a two-story home in Cinco Ranch is expensive and messy. That’s why 80 % of the residential jobs we do in 2025 are completely wireless.
- Sensors last 10 years on lithium batteries
- Communicate via encrypted 5G cellular
- Still fully supervised and centrally monitored
- Zero painting or drywall repair

Commercial Properties: Don’t Risk the Fine
I’ve worked with dozens of restaurant owners on Westheimer and warehouse managers along the Ship Channel who thought their old “local only” bell system was enough—until the fire marshal showed up.
Houston Fire Code (based on NFPA 72) is extremely clear: if you have sprinklers, an occupancy over 2,000 sq ft, or certain business types, you must have central-station monitoring.
We handle the entire process—design, install, testing, and annual certification → Commercial Fire Alarm Monitoring Services

What is considered a monitored alarm?
An alarm connected to a UL-listed central station that dispatches emergency services 24/7.
What is a monitored fire alarm system?
