postheadericon Calhan Siren Activation: June 1 2009 (All Clear)

Calhan Siren Activation: June 1 2009 (All Clear) Tube. Duration : 3.10 Mins.


This is the all-clear siren. The 1024 does NOT sound an all-clear. A hard power surge set off the COWS-1024S for about 10 seconds about five minutes after this video was taken, it was quickly shut off. Otherwise, Perfect activations for both the Federal Signal 550AT and the COWS-1024S.
