Also, there are multiple ways that an emergency communication system might receive an original warning. One example of this might be a building’s fire control system sending a notice that a smoke detector has found smoke. An emergency communication system that was built the right way should be able to receive that notice and turn it into a message that the people in the building can understand and use to decide what to do in order to save lives and property. Another example might be of the National Weather Service sending a severe weather warning (for example, by using RSS). In this example, the emergency communication system should be able to turn that warning into a message and send it in a similar way as the smoke detector example, so people will know what to do.
