Alarms Protect Your Stuff. Monitoring Protects Your People.
Monitored smoke, carbon monoxide, and water sensors connected to your ADT system — so when something goes wrong at 3 a.m., or when nobody’s home, help gets dispatched anyway. This is the part of the system that saves lives, not just property.
Life-Safety Sensors We Install
These sensors watch the dangers that don’t knock first:
Monitored Smoke Detectors
Placed where fire risk and sleeping areas demand them. When smoke is detected, the monitoring center can dispatch the fire department — whether you’re home asleep, at work, or on vacation.
Carbon Monoxide Detectors
CO is colorless, odorless, and produced by the most ordinary things in a home: furnaces, water heaters, stoves, attached garages. Monitored CO detection means an alarm that acts even when the gas has already made you too sick to act yourself.
Flood & Water Sensors
Small sensors at water heaters, washers, sinks, and HVAC drains that alert you at the first sign of a leak — catching the $15 part failure before it becomes a $15,000 floor replacement.
Freeze & Temperature Alerts
For homes in colder areas, low-temperature alerts warn you before pipes freeze and burst — the water damage claim that surprises the most homeowners.

Learn more →The Difference Between Beeping and Monitored
A standalone detector has one job: wake up whoever is home and able to respond. That fails in the most common real scenarios — nobody home, everyone asleep and overcome, pets home alone, or a slow leak in a wall that beeps at an empty house for a weekend.
Monitored sensors close that gap: the signal reaches a 24/7 center that can dispatch help and notify you wherever you are. For fire especially, minutes decide outcomes, and a monitored system starts those minutes the moment smoke appears.

Before You Decide
How much does an ADT system cost?
It depends on your home and the equipment you choose. Many customers qualify for $0 upfront on their equipment and installation, with monthly monitoring based on the protection level they pick. Your free quote gives you exact pricing for your home — no guessing and no pressure.
There’s already an ADT system in my home. Can you reactivate it?
Very often, yes. If the previous owner left ADT equipment behind, we can inspect it for free, reactivate what works, and upgrade what’s outdated — usually for much less than a brand-new system.
How fast can you install?
Faster than you’d expect: same-day installation is available on many systems when you contact us early and a crew is working in your area — it’s one of the advantages of a local dealer. If today doesn’t work out, we’ll get you scheduled the same week. Ask about same-day when you call and we’ll tell you straight whether we can make it happen.
Are you ADT, or a local company?
We’re both: Your Home Safety is a locally owned company and an official ADT Authorized Dealer. You get ADT’s nationwide 24/7 monitoring network with a local team that designs, installs, and supports your system.
