Why do we have a siren? 

The Town of Slave Lake installed a siren as part of its emergency notification system. It will only be used when there is evacuation order issued for the Town of Slave Lake.

What does the sound of the siren mean?

If you hear the siren, outside fo the monthly and annual testing period, an evacuation order has been issued by the Town of Slave Lake 

In what parts of town can I hear the siren?

If you are outside you will be able to hear the siren in most areas of town. It is not meant to be heard inside. It is a rotating siren so the sound will be softer when it is facing another direction. It will also be affected by wind direction, cloud cover and other factors.

How loud is the siren?

The sound will be the loudest at the centre of town.  The siren’s steady sound is 128 decibels at its loudest (about 50 feet from the siren) and 70 decibels at Gloryland, Big Fish Bay and the Northeast Industrial area. Most residential areas will fall within the 100 to 80 decibel range.  Check out the map of the coverage area below and the specific siren model.

Who decides when to activate the siren?

The Town’s Director of Emergency Management – usually the CAO – makes this decision based on the information at hand. It will only be used when an evacuation order has been issued for the Town of Slave Lake.
