Firefighters say smoke detectors helped alert a Hampden family to a fire in their home Tuesday night.
Hampden fire officials say they were called to Patterson Street just after 10 p.m.
When first responders arrived, they reported light smoke in the neighborhood.
But, with no flames showing in the house, it took a few minutes for crews to locate the fire.
During that time, mutual aid from surrounding towns and departments arrived.
Firefighters found heavy smoke in the back of the house and soon found the source in a second floor storage room.
They say within 30 minutes of the initial call, they were able to put the fire out and contain the damage to the upstairs area.
Four people staying at the home made it out safely, as did their pets.
The Fire Marshal’s Office is looking for the cause.
