Hotel / Restaurant, Restaurant Las Vegas, NV – Sprinkler system douses overnight fire at downtown bar March 19, 2015 viking210 An automatic sprinkler helped prevent an overnight fire from spreading at a downtown bar, Las Vegas Fire & Rescue officials said. Fire dispatchers were notified at 3:16 a.m. today that the water-flow alarm for the fire sprinkler system activated at Backstage Bar & Billiards, 601 Fremont St., fire department spokesman Tim Szymanski said. Firefighters forced their way into the three-story building and found clothing and other items too close to a water heater had caught fire, he said. The sprinkler had already doused the fire, he said. Damage was estimated at $5,000, but the blaze could have done substantial damage without the sprinkler system, Szymanski said.
