Central Alert: Updating or Removing Contact Information, Guest Access, Guardian App, and Other Information

Phone numbers, text message (SMS) numbers, and email addresses can be added to CMU's Central Alert emergency notification system by current students and employees. Additionally, guests that are not formally affiliated with CMU, like visitors to campus or contractors working on campus, may elect to opt-in via text (SMS) to receive alerts. In the event of an emergency or crisis at CMU, voice, text, and email messages will be sent to all user-provided contact numbers and addresses.


Further information on emergency preparedness at CMU can be found at http://www.cmich.edu/emergencyprep/

The Central Alert emergency notification system is powered by Rave Mobile Safety.


Summer 2020 System Changes

Over the course of the summer 2020 months, the Central Alert emergency notification system was updated to take advantage of new features. Some important changes include:

  • Contact information is now managed at cmich.edu/centralalert instead of myaccount.cmich.edu
  • Students, staff, and faculty have more direct control over their emergency notification system points of contact
  • Notifications will now be sent to cmich.edu email addresses by default
  • Campus guests / visitors now have the option to opt-in to receive emergency notifications (with the ability to opt-out at any time)
  • Weather alerts specific to the Mt. Pleasant (CMU campus) area from the National Weather Service can now be sent through the Central Alert system. Severe alerts will be sent to all Central Alert members by default, other alerts are available for an optional subscription
  • A companion mobile app (Rave Guardian) is now available that will receive alerts, provide additional safety options and methods of contact to CMU Police, and provide important contact information and / or web resources for campus and local safety resources


Student, Faculty, and Staff Auto-Enrollment Information

Current students are automatically enrolled in Central Alert using the phone number they provided in their initial application form to CMU. Generally, this number is populated in Central Alert as the student's Mobile Phone Number but can be updated with a new number on the cmich.edu/centralalert site.

Current faculty and staff employees are automatically enrolled in Central Alert using the phone number provided in the Permanent Address Information section of the Address Change form. Generally, this number is populated in Central Alert as the employee's Voice Only Contact but can be updated with a new number on the cmich.edu/centralalert site.

All current students, faculty, and staff will receive Central Alert notifications in their CMU (@cmich.edu) email accounts by default.

Guardian Companion Mobile App

Frequently Asked Questions

How does the system work?

In the event of an emergency, a notification message will be sent to each point of contact listed.


Are all fields required?

No. You may choose to include information for all listed contact methods, or only one.


How long before changes to my contact information become active?

Changes to your emergency contact information are effective immediately as long as the information is updated at the cmich.edu/centralalert site.


What happens if my contact information is invalid?

Invalid contact information in any field will result in that data being rejected. Unfortunately, due to the bulk nature of how these records are processed, there is not a way to give you direct feedback on incorrect contact information. It is very important that you make sure all contact information is valid and that no international numbers are listed in the phone number fields.


I did not receive an alert I expected, or I have another issue to report, what should I do?

Submit a ticket to the Help Desk for investigation and further assistance.


How can I remove myself from the emergency notification system?

Go to cmich.edu/centralalert and delete each individual point of contact listed. Important! By removing yourself from the emergency notification system, your CMU (cmich.edu) email address will become the default method to notify you in the event of an emergency or crisis.


What happens when I graduate, stop taking classes, or stop working at CMU? Is there a way to continue to receive alert notifications?

Students are removed from Central Alert after the conclusion of their last registered course. Faculty and staff employees are removed shortly after their last date of employment. Unfortunately, indefinite continued access to the Central Alert system after separation from CMU is not possible for a variety reasons. However, temporary access is still available to those that wish to opt-in as guests.
