Walk test initiated
Senior Airman Alan Rosales, 28th Civil Engineer Squadron electrician journeyman, initiates the walk-test feature on the fire alarm system at the Ellsworth AFB, S.D., Jefferson Dormitory during an annual inspection March 13. The feature saves time and manpower by allowing electricians to test the accuracy of each fire alarm pull station throughout the dormitory in one centralized location.
