At ~8:40 PM, Westmorland 911 dispatched Station 20 (Murrysville VFC) for an Automatic Fire Alarm (AFA) at the Murrysville Rehabilitation and Wellness Center. Station 20 immediately responded with Engine 20 (3 firefighters) with Lieutenant 20 going directly to the scene, and 5 firefighters going to Station 20 to crew Truck 20. Westmorland 911 also dispatched the following stations to assist Station 20: Station 610 (Murrysville Medic One), Station 78 (Sardis VFC), Station 64 (White Valley VFC), Station 22 (Export VFC) and Station 236 (Holiday Park VFC). Engine 20 was first on scene, and found no smoke or fire. Upon Lieutenant 20 arrival on scene, command was established, and a primary interior search was conducted, with negative results. It was determined that the AFA System had malfunctioned, and the system was reset by the facility's maintenance staff. Command 20 cancelled all additional responding units, and Engine 20 returned to service and station.
