The Village of Sherman has installed a new emergency outdoor siren warning system replacing a 1960's era system that was unreliable and expensive to maintain. The new system is intended to warn residents, when they are outside, of an impending emergency.

Alert Warning Signal - is a five (5) minute steady siren. The sirens rotate when broadcasting a signal and will have a sound that will decrease in volume as it rotates away from you and increase in volume as it rotates toward you. This is still considered a steady siren warning signal. This signal is used during severe weather or other peacetime emergencies such as an evacuation needed due to a hazardous materials incident, etc. When you hear this signal you should take shelter and turn on your radio or television and listen for essential emergency information.

Attack Warning Signal - in case of an attack on the homeland, the village warning signal is a five (5) minute wavering siren tone. This signal means that an actual attack against the United States has been detected and that protective actions should be taken immediately.
