Advanced Bell SchedulingAccurate timekeeping is essential to the function of our society. For decades, we have relied on synchronized wired clocks to measure our lives.
The master clocks of wired and wireless systems share similar characteristics, including:
The main difference between wireless and wired clock systems is how they connect all the clocks within the system. As the name implies, the master clock of a wired system has a physical connection to each clock with a wire. Wireless master clocks, in contrast, send the proper time to their connected clocks using radio frequencies or internet signals.
Wired clock systems also self-adjust to ensure accurate readings. While the specific correction protocol can differ between clock manufacturers and models, it typically involves correcting minutes and seconds on an hourly basis. Additionally, most master clocks correct the hour display every 12 hours. This automatic correction ensures the clocks will continue to give an accurate reading even after experiencing a situation like a prolonged power outage.
One common use for wired wall clocks is in schools. Synchronized wired clocks for schools help instructors stay on track in their classes, while a consistent bell system ensures students leave and arrive on time. If clocks were asynchronized, students may move to the next classroom before that class gets out, so having the same bell schedule in every room is essential.
Wired clock systems are also valuable for hospital settings, where keeping accurate time is of the utmost importance. The time determines:
The reliability of a wired clock system allows health care facilities to stick to their strict timelines and ensure smooth, consistent operation, whether personnel is at the nurses' station or in a patient's room.

Wired clock systems are timeless for a reason. There are many advantages to using them in your buildings, including:
Our wired clocks are designed to last the life of the facility with minimal maintenance.
With a large range of universal replacement options at different voltages, we can provide reliable replacements for broken clocks without the cost of an entirely new system.
In addition to sending time to our clocks, National Time's master clocks provide extensive bell scheduling options, as well as time-sync to PA systems.
With our network-enabled master clocks, you can ensure your clock system is synchronized with National Institute of Standards and Technology (NIST) atomic clocks or your own building's computer system.
Wired clocks are better able to withstand electromagnetic interference (EMI) than wireless clocks, making them more reliable for areas that experience high electrical noise.
With our network-enabled master clocks, you can ensure your clock system is synchronized with National Institute of Standards and Technology (NIST) atomic clocks or your own building's computer system.
Rest assured that all wired clocks throughout your facility are accurate and on the same time for consistency throughout your operations. That al
With a wired clock system, you don't have to worry about changes in wireless technology, FCC rules or IT infrastructure. Your clocks will provide reliable time regardless of the infrastructure changes around them.
At National Time & Signal, we build a wide assortment of digital and analog wired clock systems for schools, theaters, hospitals, spas and other facilities. Our most popular models include the following.
Our Rotary Drive Synchronous (RDS) Analog clocks are the most advanced analog clocks in the industry. The systems incorporate innovative microprocessing technology with infrared positioning sensors to create the smoothest, most accurate timekeeping system possible.
The mechanism in our RDS Analog clocks is especially durable thanks to its powerful rotary stepper motor and indexing technology. These features also make it remarkably cost-effective — powering one of these clocks costs less than 10 cents per year, according to our findings.
Additionally, the revolutionary rotary drive design enables our RDS clocks to instantly correct all connected clocks in the system to the exact hour and minute, saving you the time and effort you would have spent adjusting individual clocks. They're also compatible with existing three-wire synchronous clocks, so you can easily integrate them into your existing system.
National's Spectrum Wired clocks are compatible with a range of wired clock system types, including:
The Spectrum's energy-efficient design uses less power than previous models, making it an eco-friendly clock system. Its low power consumption also allows you to create longer wire distances between the clock and the master clock with fewer power supplies, making it possible to keep time accurately even throughout large buildings.
What's more, the onboard microprocessor works to monitor hand position, which ensures an accurate time display without user intervention. Instant correction and increased hand visibility make it an ideal option for hospitals and care facilities that need to quickly view accurate, consistent times.
The powerful synchronous motor and wear-tolerant mechanism of our EX Analog clocks combine to create a low-maintenance system that can outlast even a building's useful life span.
They're compatible with most master clocks, so you can easily install them into almost any existing system, like a school building or hospital. They also feature a simple resetting scheme, so if you find an errant clock, you can easily set it to the correct time. These clock faces come in up to 24-inch diameters and are available in single- and double-face designs.
Like with many of our analog clocks, the current consumption of our digital wired clocks is incredibly low, helping your institution increase its environmental friendliness while still delivering the high performance and accurate 60Hz timekeeping you need.
National Time & Signal produces three series of digital wired clocks:
While each product series has its own distinct characteristics, they all share the following key features:
Wired master clock systems from National Time & Signal can handle thousands of events on multiple schedules, making them suitable for busy environments like medical facilities and school buildings.
Here's what's special about our master clock systems:
Partner with National Time & Signal for the most reliable, long-lasting wired synchronized clock systems in the industry. With our century of experience in providing top-quality clock products, you can rely on us to help you meet your timekeeping needs.
