• The table contains the values of minimum sound pressure level and volumes depending on the
direction of emission @ 1 m accordance to EN 54-3 (except 90° angle) in connection with the flat
base.
• The values may be up to 0.5 dB lower owing to rounding.
• The values for 90° are informative and are not minimum specifications in accordance with EN 54-3.
• When using the IP base (806201, 806202) the values can deviate up to -3 dB.
