Retail, Shopping Mall Phoenix, AZ – No injuries as sprinkler system knocks down fire at Guitar Center December 9, 2016 viking210 The sprinkler system was the hero of the day after a fire broke out at a Guitar Center off of I-17 and Peoria Avenue overnight Wednesday. Phoenix fire officials said sprinklers put out most of the flames before crews arrived. The Guitar Center has water damage, but fire officials said had the sprinklers not been in place, the story could have gone much differently. The Guitar Center doesn’t have a fire wall, meaning the flames could have easily spread to surrounding businesses in the strip mall. Luckily, no one was injured. Detectives will now investigate what cased the fire to break out.
