You cant directly tell if the siren is on or off. Yiu could check the alarm state. If the alarm state is 3, it means the siren should be on.

The siren times out after 5 minutes and the alarm state changes from 3 to 2.

The command S? returns the alarm state.

eg
command: S?
Reply: S?03 menas alarm state 3
