Calhan tests their Federal 550-AT siren Once Annually, first Friday in May at 7:00PM. Test is postponed if cloudy that day. Test protocol is: three one minute activations. Allow to wind totally down and then go into three-minute Alert.
My siren out at the Paint Mines is tested once a month on the second Monday between noon and 4 PM if weather permits, otherwise, it is Silent Tested.
Same goes for my other one at home, in Calhan, it is Always silent tested, except for on test day, then its activated along with the town's siren.
Still close enough to a Fed Sig 550AT to drive out on test day: First Friday in May - 7PM!
