Danbury Fire Department Adopts Gentler Dispatch Alerts to Reduce Stress

The Danbury Fire Department in Connecticut has implemented a new dispatch alert system that gradually increases in volume and uses a calm, computerized voice to provide emergency details. This replaces the previous high-volume, jarring alarms that were found to increase firefighters' heart rates and stress levels. The new system, which cost around $500,000 from American Rescue Plan funding, is part of a nationwide trend to adopt gentler alert methods in order to improve firefighter health and response times.

Why it matters

Sudden cardiac events are the leading cause of on-duty firefighter fatalities, and research has shown that immediately loud alarm systems can significantly increase heart rates and stress. By implementing a more gradual, calming alert process, the Danbury Fire Department aims to reduce these physiological impacts and ultimately improve firefighter safety and response capabilities.

The details

Danbury's new Phoenix G2 system, made by Honeywell, starts alerts with a single soft tone followed by a computerized female voice calmly announcing the emergency details. The volume then gradually increases as red lights flash and a countdown timer displays, all integrated with the department's computer-aided dispatch. This replaces the previous high-volume, fluctuating tone system that firefighters described as "jarring" and "overwhelming."

• The new alert system went online in September 2025.
• Danbury used around $500,000 in American Rescue Plan funding to implement the new system.

What’s next

Danbury plans to continue monitoring the impact of the new alert system on firefighter health and response times, with the goal of potentially serving as a model for other departments looking to adopt similar technology.
