At ~ 4:08 AM, Westmorland 911 dispatched Station 20 (Murrysville VFC) for an Automatic Fire Alarm (AFA) at the Murrysville Dairy Queen. Station 20 responded with Truck 20 (2 firefighters), with Lieutenant 20 going directly to the scene, and an additional firefighter at the station ready to deploy Engine 20. Westmoreland 911 dispatched the following stations to support Station 20: Station 64 (White Valley VFC), Station 22 (Export VFC), Station 78 (Sardis VFC), Station 236 (Holiday Park VFC), and the Murrysville Police. Lieutenant 20 was first on scene, established command, found no fire or smoke coming from the structure, and cancelled all responding fire units except for Truck 20. Upon arrival of Truck 20, entry into the structure was made using the "Knox Box" Key, and the interior search found no smoke or fire. The business key holder was notified, and the AFA System was reset. Upon securing the building, Command 20 returned Truck 20 to service.
