Fires, lockdowns and severe weather can create panic at any school. With audio communication during these emergencies, schools can prevent injuries, improve response times and stay up to code.

That’s the intent of recent updates from the National Fire Protection Association (NFPA) and the International Building Code (IBC) that now require an emergency voice alarm communication system in Group E buildings.

In a white paper from Johnson Controls, you’ll learn how emergency voice alarm communication systems create clarity in fast-moving events.

Emergency voice alarm communication systems offer multiple advantages in schools – especially compared to traditional horn-strobe alarms, including:

  • Pre-recorded messages can be tailored to the school’s layout
  • General public address messaging (encouraged under NFPA section 9.6.3.11.2)
  • Audio that reaches non-native English speakers and those on the autism spectrum

The white paper also highlights practical considerations for schools planning upgrades. For schools looking to consolidate systems, you’ll discover new fire alarm control units like the 4017ES that integrate audio functionality for multiple scenarios.
