1. A speaker system with acoustic event detection, the speaker system comprising: a number of speakers;a head unit including an output circuit structured to output an output signal to the speakers to cause the speakers to output an audible sound; andan acoustic event detection module structured to receive signals from the speakers and to detect an acoustic event based on the signals received from the speakers,wherein the head unit further includes a supervision circuit structured to provide electrical supervision to the speakers,wherein the acoustic event detection module includes a processing unit structured to analyze the signals received from the speakers and to determine whether the signals indicate the acoustic event, andwherein the acoustic event detection module includes one or more filters electrically connected between the supervision circuit and the processing unit and being structured to filter out the electrical supervision and to allow the signals received from the speakers to pass through. 2. The speaker system of claim 1, wherein the acoustic event detection module is disposed in the head unit. 3. The speaker system of claim 1, wherein the acoustic event detection module is disposed in one of the speakers. 4. The speaker system of claim 1, wherein the output circuit is an alarm output circuit and the output signal is an alarm output signal which causes the speakers to output an audible alarm. 5. The speaker system of claim 1, wherein the acoustic event is a gunshot. 6. The speaker system of claim 1, wherein the electrical supervision is direct current supervision. 7. The speaker system of claim 1, wherein the acoustic event detection module includes an analog to digital converter structured to convert the signals received from the speakers to digital signals. 8. The speaker system of claim 1, wherein the speakers each include a capacitor electrically connected in series with a transformer or a capacitor electrically connected in series with a speaker element. 9. The speaker system of claim 1, wherein the speakers each include a speaker element structured to detect sounds and output signals representing the detected sounds to the acoustic event detection module. 10. The speaker system of claim 1, wherein the speakers are electrically connected in parallel with each other. 11. The speaker system of claim 1, further comprising: an end-of-line resistor electrically connected in parallel with the speakers. 12. An acoustic event detection modification kit for a speaker system including a number of speakers, the acoustic event detection modification system comprising: an acoustic event detection module structured to receive signals from the speakers and to detect an acoustic event based on the signals received from the speakers; anda head unit including an output circuit structured to output an output signal to the speakers to cause the speakers to output an audible sound,wherein the head unit further includes a supervision circuit structured to provide electrical supervision to the speakers,wherein the acoustic event detection module includes a processing unit structured to analyze the signals received from the speakers and to determine whether the signals indicate the acoustic event, andwherein the acoustic event detection module includes one or more filters electrically connected between the supervision circuit and the processing unit and being structured to filter out the electrical supervision and to allow the signals received from the speakers to pass through. 13. The acoustic event detection modification kit of claim 12, wherein the acoustic event detection module is disposed in the head unit. 14. The acoustic event detection modification kit of claim 12, further comprising: a modified speaker structured to be installed in addition to or replace one of the speakers of the speaker system,wherein the acoustic event detection module is disposed in the modified speaker. 15. The acoustic event detection modification kit of claim 12, wherein the acoustic event is a gunshot. 16. A method of modifying a speaker system including a number of speakers to include acoustic event detection, the method comprising: providing an acoustic event detection module structured to receive signals from the speakers and to detect an acoustic event based on the signals received from the speakers;providing a modified head unit including an output circuit structured to output an output signal to the speakers to cause the speakers to output an audible sound; andelectrically connecting the acoustic event detection module and the output circuit to the speakers,wherein the modified head unit further includes a supervision circuit structured to provide electrical supervision to the speakers,wherein the acoustic event detection module includes a processing unit structured to analyze the signals received from the speakers and to determine whether the signals indicate the acoustic event, andwherein the acoustic event detection module includes one or more filters electrically connected between the supervision circuit and the processing unit and being structured to filter out the electrical supervision and to allow the signals received from the speakers to pass through. 17. The method of claim 16, further comprising: disconnecting a current head unit of the speaker system from the speakers. 18. The method of claim 16, further comprising: providing a modified speaker including the acoustic event detection module; andelectrically connecting the modified speaker to the speakers or replacing one of the speakers with the modified speaker. 19. The method of claim 16, wherein the acoustic event is a gunshot.
