NOTES:
• Reverberant
dBA measurements are a minimum UL rating based on sound level measurements made in UL’s reverberant test chamber.
• Anechoic dBA measurements are a minimum ULC rating based on sound pressure level measurements made in ULC’s anechoic test chamber.
• The sound pressure level decreases by 3 dB at an angular displacement of 75° from the line perpendicular to the speaker’s center. The SPL
decreases by 6 dB at an angle of 85° from that line.
* Only marked settings may be used for ULC fire alarm applications.
