History
Leveraging Generations of
Experience, Commitment and Trust
Our company began as the successors to the
Hahl Pneumatic Clock System of the 1870´s, making us the most experienced manufacturers of Master Time
Systems, Outdoor Clocks, and Life Safety Systems in America.
Three generations and ten decades
after the founding of our company, we remain committed to our craft. From clocks driven by moving
pendulums, to the space age precision of the moving Cesium atom; from pull cord fire alarm bells to fiber
optic networks, our product solutions keep pace with advanced technologies and the needs of the
future.
Key Moments in Our History:
1877: Hahl Clock Company of Chicago, Illinois, introduces the
world's first pneumatically controlled master clock system. This invention sets the stage for the
practical use of coordinated time by building occupants. It is so impactful that August Hahl earns the
"John Scott Award" for the outstanding contribution to the "comfort, welfare, and happiness" of
mankind. 1918: Rolland Fulton, former Hahl Clock
Company salesperson, purchases the company, relocates to Detroit, Michigan and founds the Time Systems
Company. The new company continues to manufacture the successful Hahl pneumatic clock
system. 1920: The company engineers and
manufactures electric minute impulse clock systems, tower clocks, nurse call systems, automatic telephone
systems and becomes a pioneer in America's early fire alarm system industry. 1930: The Time Systems Company reorganizes and incorporates as
National Time and Signal Corporation and introduces industrial timing systems for Detroit's growing
automotive industry. 1940's: National Time and
Signal Corporation suspends product manufacturing and re-tools to support the World War II effort. A
majority of the output was destined for the famed B-24 Liberator bomber production at the immense Henry
Ford Willow Run facility. 1950's: The first
individually correctable synchronous motor driven clock system is introduced by National Time and Signal
Corporation. 1990's: National Time and Signal
Corporation develops the world's first microprocessor controlled, instant reset analog clock and unveils
its state of art digital communication intelligent fire alarm system. 2000's: National Time and Signal Corporation improves the
digital clock line creating the most green, power efficient clocks available in the industry. Remote
connectivity to their LIfe Safety systems is moved to the "cloud" with the introduction of
On-PointTM internet connectivity. Today: The company continues to develop technological advances,
which include LAN/WAN, WiFi, GPS and web-enabled systems for today's needs. Interactive Graphicial
Displays (IGDs) integrate Life Safety systems with informational displays for weather, building
directories, way-finding, room scheduling and event promotion.
