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) HIGHEST STANDARDS " ....only sound level meters that comply with ANSI S1.42 should be used for the assessment of fore alarm systems..." " ...Testing of Audible Alarm Notification Appliances shall be done upon initial acceptance and semi-annually" " ...Sound pressure shall be measured with sound level meter meeting ANSI S1.4a, Specifications for Sound Level Meters, Type 2 Requirements. Levels throughout the protected area shall be measured and recorded...." NFPA72 14.4.2.2 (15)
