You said 1-2 seconds earlier... so let me take a few guesses:
1.) The radio signal (or telephone signal) got scrambled or something somehow and deactivated the siren early.
2.) Newer sirens have secret detectors that detect if someone is nearby. Hey, it's a good idea... they don't want to get sued for blowing someone's eardrums out...
3.) Something in the siren broke (blew a fuse?)
4.) The power line went down.
Now, if it was 4 seconds...
1.) The sirens might possibly be coded to only sound for certain times. For example, if a siren is surrounded by houses it will be coded for only a few seconds, if it was in the forest it would sound longer.
2.) Something broke later ^.^
3.) Someone somehow decoded the data sent to deactivate the siren and "flipped the switch", so to speak, with a radio transmitter of some sort.
4.) Someone messed with the power.
Now, I know all of these answers are improbable, I'm just giving random answers for fun (hey, one of them may be right.)
And for the non-rotating siren... most likely they either disconnected the rotator motor for some reason (direct the sound to only one location) or the belt broke. And that is only if the siren is an older model. Although you said it was placed there 10 months ago, it may still just be an older model scrapped by another community. You never know.
If at first you don't succeed, destroy all evidence indicating that you tried.
