This Federal Signal Thunderbolt 1003 was tested at 6:33 PM tonight 5/5/19, I thought it would do alert like most towns do but to my surprise, it did HIGH|LOW or rather Hi|Alert as the bottom solenoid was inoperative.
It ran for a minute then shut down, the 3 SRNB's sounded Fast Wail but two didnt rotate either there programed that way or the rotator mechanism is busted.
Enjoy
