How is re-sounding them every 8 minutes worse?! Every siren system should do that! Everybody's email including mine was not about making them sound the sirens longer anyway, it was about adding more sirens to their 5 year old system and getting better ones!2t22boy wrote:Their nasty E-mails made the situation worse...they will keep re-sounding them every 8 mins!
