WHY dBchecker?

Merely “listening” or utilizing any sound level meter available is not a reliable method for testing audible alarm notification appliances. Many of the meters currently on the market do not meet the requirements for NFPA 72. dBchecker™ conforms to ANSI S1.4a, which is required to meet the standard set forth in the latest edition of the National Fire Alarm Code. (NFPA72)
