If your fire alarm system still uses a landline, it may no longer meet code once AT&T shuts that line down.
This is a serious issue for commercial buildings, apartments, healthcare facilities, schools, and public spaces across Illinois.
Sentry Security helps buildings stay compliant without landlines.

Why Landlines Matter to Fire Alarms
Many older fire alarm panels were designed to send emergency signals over phone lines. When those lines are removed, alarm signals may never reach the monitoring center or fire department.
That can lead to:
-
Code violations
-
Failed inspections
-
Insurance issues
-
Delayed emergency response
Fire protection depends on reliable communication, not outdated phone service.
What Fire Codes Expect Now
Fire codes still require fire alarms to:
-
Send signals immediately
-
Reach a listed monitoring center
-
Stay operational during outages
Systems relying on landlines often fail these requirements once phone service changes.
Sentry Security upgrades systems using modern communication paths that meet today’s expectations.
