Systems and methods for intelligent operation and testing of backup-powered safety devices such as exit signs, emergency lights, smoke alarms, and like devices are generally disclosed herein. In some embodiments, an indicator is used to provide a display of the operational status of the safety device, as well as a testing or charging procedure status for a backup power source. The indicator may be used to provide a definitive indication of whether the testing or charging procedure was conducted, and whether such testing or charging procedure either failed or succeeded. In further embodiments, a single indicator provides each of the operational, testing, and charging status indicators for predefined periods of time using a single visible indicator display provided within the safety device. |
