Chubb Fire Security Ltd.

Chubb Fire Security Ltd. is a British fire and security company. Chubb's origins stretch back to founders Charles and Jeremiah Chubb, who patented their Chubb detector lock in 1818. The company expanded into fire protection after the Second World War.

Chubb built specialized airport and industrial apparatus in the United Kingdom for several years. In the 1970s, they introduced the Pathfinder crash tender, a few of which were delivered in the United States.

In the 1990s, Chubb entered into a partnership with National Foam, building industrial fire trucks under Chubb National Foam (CNF) nameplates.

Today, the company is part of UTC Fire & Security, a division of United Technologies.
