National Time & Signal manufactures the industry's premier synchronized clock and fire alarm systems.
National Time & Signal
Time… It is part of our name, part of our product line.
We work with time and time has worked for us. We are among the most experienced designers and manufacturers of quality timing mechanisms in the industry. But time does not tell the whole story. While we are widely known for our achievements in master clocks and large outdoor clocks, our work in commercial fire alarm systems is sometimes overshadowed by time.
The fact is, National Time & Signal Corporation can equip your largest projects with – not just large outdoor clocks – but complete master clock systems and commercial fire alarm systems and signaling systems of the highest technology.
