Fire Safety Sounders

Piezo Technologies is the leading producer of fire safety sounders for Self-Contained Breathing Apparatuses (SCBAs). Our sounders emit powerful audible alarms within the human hearing range (2-4 kHz), ensuring that nearby responders and incident command are notified if fire fighters become lost, trapped, injured, disoriented, or run out of air. They play a critical role in notifying the wearer and nearby responders to unsafe conditions such as noxious fumes, combustible fumes, high temperatures, and other hazards.

Our Personal Alert Safety Systems (PASS) fire safety sounders are approved by the National Fire Protection Association (NFPA) to protect firefighters and emergency responders.
