Firefighters responded to a sprinkler flow alarm at approximately 9 p.m. Tuesday evening at the Chapin Mansion in Niles.

Chief Larry Lamb, of Niles Fire Department, said the building uses a boiler for heating purposes and there was a small leak in the building’s steam pipe located next a sprinkler head. The leak caused the sprinkler to go off.

“It was in the basement so very little damage to the historic building occurred,” Lamb said. “We called a restoration company in to limit any additional water damage as well as a sprinkler firm to reset the system.

Lamb said several City of Niles staff members responded, with some remaining at the property working with the contractors until roughly 2 a.m.

Niles Township Fire assisted on the call.
