The M1 has the siren driver built in. All you need are 8 ohm speakers, not self contained siren/speakers. However Output 2 can be configured for voltage output and a self contained siren added to it. Sort of waste of money though.
The nice thing about using the built in siren generator is that all the siren sounds are coordinated and the same siren sound is coming out of all speakers. You do not have a mismatch of siren sounds.
