How Sentry Security Ensures 911 Reliability Without Landlines?

Sentry Security uses modern alarm communication paths—not phone lines—to make sure emergency signals reach 911 fast and accurately.

As landlines are retired across Illinois, older alarm systems can lose their connection to emergency services. Sentry Security prevents that by designing systems that stay connected when phone lines disappear.

Why 911 Reliability Changes Without Landlines

Traditional alarm systems were built to dial out over copper phone lines. When those lines are shut down, emergency signals may never leave the building.

That’s a major risk for systems relying on professional monitoring—especially in emergencies where seconds matter.

How Sentry Security Keeps 911 Working

Landline-Free Alarm Communication

Sentry Security designs systems that use wireless security systems with cellular and IP connections. These paths stay live even during phone outages.

Smarter Emergency Routing

Sentry integrates 911inform and RapidSOS to send real-time location and building data directly to first responders.

Engineered for Reliability

Every system is planned through professional system design and engineering to avoid single points of failure.

Always-On Monitoring & Maintenance

Reliable 911 access depends on systems being tested and maintained. Sentry provides continuous monitoring plus scheduled maintenance and inspections.

Where This Matters Most

Reliable 911 access is critical for:

• Senior care and medical monitoring environments

• Multifamily properties

• Commercial buildings

• Healthcare facilities

• Education campuses

If your system still connects to a phone jack, 911 reliability may already be compromised.

Sentry Security is a trusted Illinois provider with a strong track record, recognized through industry awards and proven results in real-world case studies.

We don’t rely on outdated phone networks we build systems ready for today and tomorrow.
