Sound pressure level depending on the height of the ceiling and distance
Both the following tables provide a short guide for the expected sound pressure level in dB(A) taking account of
the installation height (height) and the diagonal distance to the alarm device. The idealised values calculated here
for the sound pressure level may, however, differ in practice. The reasons for this are the actual ambient conditions
for the alarm and the type-dependent emission relationship.
