We measured sigle SPL of DF1027A ( low-frequency signal generator ).
SPL of DF1027A=105dBA
SPL of alarm is 85dBA when the speaker's output is 0Vpp.
SPL of alarm is 105dBA when the speaker's output is 6Vpp(the SPL of speaker is 100dB).
So the SPL of alarm is form 85dBA to 105dBA adjust.
In this mode the siren has a current consumption of 500mA.
