Purposeful Redundancy

Redundant communication channels are vital in an emergency.
Using a combination
Because of the possible limitations of each system, a campus should not rely on any single technology. Using redundant systems will increase the likelihood that vital information will reach people when they need it most. A combination of a siren, text-message system, outdoor voice speakers, intercoms and LED signs will give campus administrators and security staff the best opportunity for disseminating vital information during an emergency.
Electricity is critical for operating many of these systems, so redundancy in power sources also is critical. In case of a power loss, have a battery pack, a generator or solar system available for backup.
And that is not the end of communications opportunities. Two-way radios provide a communications channel. Almost all campuses have an Internet site that can be used to post updates and warnings that will be available to those near a computer or a phone with Web access. An advantage of this source is that updates can be posted frequently and remotely.
Many colleges and universities, as well as a few high schools, have a radio or television station. During a crisis, these broadcast outlets can disseminate information. Also, some campus stakeholders may turn to local commercial radio and television stations, as well as local news websites for information. So be sure to keep these outlets updated.
Remember that a campus notification policy should be part of a larger emergency plan. As with any plan, it is important to put it in writing, share it with anyone involved — and then practice, practice and practice it.
Also, remember to incorporate other security tools that already exist on campus. For example, a camera system can play a vital role in making quick decisions at a time when events are transpiring quickly. If an evacuation is in order, cameras can help administrators and security personnel make sure the selected site is safe.
The goal of an emergency communications plan should be to make as much information as possible available through many different communications paths. In an emergency, when people are in danger, information is critical. By planning ahead and using redundant systems and outlets, lives may be saved and property damage limited.
