Abstract: The system and device for rapid communication with emergency responders during a crisis includes a wearable alarm and notification device. The wearable device is worn by, for example, the staff and faculty members of a school. When activated, the wearable device sends a signal to a central system or server, the central system simultaneously triggering numerous actions. For example, the server simultaneously performs the following actions: sending alerts to parties based on predefined groups; causing the public address system to play an alarm or a prerecorded message; sending messages by additional other means, for example SMS, email, phone calls, push notifications, and so forth; and triggering a lockdown, the lockdown either of the area around the activated mobile device, the entire campus, or a subset of the entire campus.
