We have a unit in the shop with a sapphire. When in position 3 the speakers give a quiet timed bark. If you push manual, you get the siren but it is very muted, also the PA is muted. We replaced the speakers, amp, and controller with equipment from another vehicle and still have the issue. Are there any tricks we could be missing? We even ran a jumper speaker wire from the amp to the speakers with no luck.
Thanks for any info!
