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 (NFPA 72).

Designed to the 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 measure 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 (15)

CAN/ULC S536-04, G1.1
"The sound level meter shall have a measurement range that permits readings as low as 35 dBA..." "The use of a quality meter to minimize any measurement errors. ANSI S1.40, Specifications for Acoustic Calibrators, is one standard that can provide guidance on the subject."
