Everyone’s heard the siren of a fire truck as it zooms down the street. But the sounds associated with fire alerts have changed over time. All around the Pittsburgh region, fire stations alert volunteers and the public in distinct ways.

A Boston man described by his lawyer as a "die-hard Patriots fan" has pleaded not guilty to pulling a fire alarm that roused the visiting Pittsburgh Steelers from their hotel beds ahead of their playoff game against New England.

Dennis Harrison was released on personal recognizance at his arraignment Monday on charges including disorderly conduct and disturbing the peace.

Police say the 25-year-old East Boston resident pulled the alarm at the Logan Airport Hilton at about 3:40 a.m. Sunday. Authorities quickly determined it was a false alarm.
