Wheelock

Founded in 1922 as "Wheelock Signals, Inc.", Wheelock, Inc. is a long-time maker of fire alarm notification appliances. After being independent from 1922 to 2005, the company was acquired by Cooper Industries in 2006. In 2012 Cooper Industries themselves were acquired by the Eaton Corporation, and so were Wheelock along with them. Nowadays the Wheelock name is not as prominent as it once was, but the company still continues to produce notification appliances for fire alarm systems.
