Someone in the Old Saybrook CT police dispatch screwed up, and sent out a terror alert message over the town's siren system. Main purpose of the sirens is warning for the Millstone power plant and storms.
Their sirens are 2805 missing a screen at the FD, also used for fire calls (5 rounds of wail), a 2910 on RT 1 replacing a 2016, and a 2008 at Saybrook point.
