A system and method for testing fire detection and fire annunciation devices of a fire alarm system includes a central operations system, which provides a link between a control panel of the fire alarm system and a mobile computing device operated by a technician. During a walkthrough test, the on-site technician activates fire detection or fire annunciation devices of the fire alarm system and the activated devices signal the control panel and event data are generated. Event data from the control panel are sent to the central operations system to be stored. The central operations system sends the event data to a mobile computing device operated by the technician. The on-site technician is then able verify that the devices are physically sound, unaltered, working properly, and located in their assigned locations.
