Troubleshooting a Siren

When troubleshooting a siren, always disable all of the options to simplify diagnosis. Turn off Siren Lock and remove the wire from the Park Kill input. If the PA microphone is a plug-in model, unplug it. With these options disabled, determining the problem is much less complicated. Be sure to re-enable all of the options after the problem is fixed.
