The Jersey City Fire Department responded to a small fire at the Monaco luxury high-rise early Wednesday morning, authorities said.
After arriving to the Washington Boulevard apartment complex at 1:30 a.m., firefighters located a fire in the heating component of one of the building's units, Jersey City spokeswoman Kimberly Scalcione said.
The small fire, which set off two sprinkler heads, was determined to have been caused by a faulty heating system, Scalcione added.
One apartment sustained fire damage and two others had minor water damage, the spokeswoman said, adding that no injuries were reported.
