At ~1:23 AM, Westmorland 911 dispatched Station 20 for a Residential Automatic Fire Alarm at 5026 Prides Court. A Station 20 firefighter responding directly to the scene, determined that the AFA was set off due to a low battery, notified Westmorland 911 of the situation, and cancelled Station 20's response as Truck 20 (4 firefighters including Lieutenant 20) was preparing to depart Station 20.
