911 still works but only if your system is properly upgraded.
When traditional landlines are shut down, old alarm systems may no longer send emergency signals. That can delay police, fire, or medical response when seconds matter.
Sentry Security helps Illinois homes and businesses maintain reliable 911 access without landlines.

Why Landline Shutdowns Affect 911
Many legacy alarm and fire systems were designed to call 911 or monitoring centers over copper phone lines. When those lines are retired, emergency signals may never leave the building.
This puts professionally monitored systems & the people who depend on them—at risk.
How Modern Systems Handle 911 Calls
Sentry Security designs systems that do not rely on phone lines, using:
- Cellular and IP communication via wireless security systems
- Enhanced emergency routing with 911inform
- Real-time responder data through RapidSOS
These technologies deliver accurate location and facility information directly to emergency responders.
What Happens to 911 Access When Landlines Are Shut DownFire and Life-Safety Compliance Still Applies
For businesses, schools, healthcare facilities, and multifamily buildings, 911 reliability is not optional.
Sentry Security ensures fire alarm systems remain code-compliant through proper system design & engineering and ongoing maintenance and inspections.
Who Is Most at Risk
You should act now if you manage or live in:
- Senior care or medical monitoring environments
- Multifamily properties
- Commercial buildings or retail
- Healthcare or education facilities
- High-value or regulated businesses
If your alarm system still connects to a phone jack, 911 access may already be compromised.
