At ~18:47 PM, Westmoreland 911 dispatched Station 20 (Murrysville VFC) for an Automatic Fire Alarm (AFA) at a home on Murry Highlands Circle. Station 20 responded with 10 firefighters (including Assistant Chief 20 and Captain 20) going to the station to crew Truck 20 and Engine 20, while 3 firefighters (including Sergeant 20) went directly to the scene. Westmoreland 911 also dispatched the following stations to support Station 20: Station 9 (Level Green VFC), Station 22 (Export VFC), Station 64 (White Valley VFC), and Station 78 (Sardis VFC). Command 20 returned all dispatched stations, after the direct responding firefighters found that the home's AFA System had a false activation. Truck 20 and Engine 20 remained in service and in station.
