Correction from the last post, after testing the cclx file
Both the Siren Type and Sound Type durations need to be increased

The Siren Type sets the total duration for the siren (default 1 second)

The sound type determines the frequency and duration for each of 2 tones (default 100 ms of 500 hz and 400 msof silence). This combination gives 2 pulses of 100ms sound  + 400ms silence = total  1 second. In most sirens a 100 ms burst can be heard. The default is short so as not to make too much noise at night.  In your case, the siren is probably slow to respond event to a 1 second pulse, so you either do not hear it or hear it intermittently

You can increase the Siren Duration to 2 seconds and the sound type "tone 1" duration also to 2 seconds. This should produce a single 2 second sound on the siren.
As an example if you keep the Sound type tone 1 duration at 2 seconds but increase the siren type duration to 4 seconds, you would hear 2 bursts of 2 seconds
