MasterSync Wireless Clock System
While not strictly “signage,” the MasterSync Wireless Clock System by Acroprint is certainly a system that allows everybody on the premises to see the same thing whenever they look! I’m also a bit of a sucker for anything that’s wireless – when it comes to our electronics, wireless is the WAY TO GO!
Synchronize the wall clocks throughout your facility with atomic accuracy. A single transmitter with a standard antenna can cover up to 250,000 square feet!
MasterSync at a glance
- Economical — A single transmitter with a standard antenna can cover as much as 250,000 square feet. Compare to other systems that require repeaters or additional transmitters — at extra cost — to cover your entire facility. Because the transmitter is wireless, it can support an unlimited number of wall clocks.
- Easy — Installation is as easy as hanging a picture! Simply place the wireless clocks where you want, connect the transmitter to the GPS unit and you’re up and running. No special tools, equipment or expertise required.
- Accurate — The transmitter receives time signals from the world-wide GPS satellite network, keeping your wall clocks incredibly accurate and perfectly synchronized. (NTP time synchronization available for those who prefer.)
- Attractive — Wall clocks are available in a wide range of styles and mounting options. Clock styles can be mixed and matched to meet your needs and to coordinate with the décor throughout your facilities.
Easy to install
Imagine perfectly synchronized clocks, helping keep everyone on time no matter where in your facility they might be. Now imagine being able to install this system without cutting holes in your walls, running wires or petitioning your Information Technology department for help. With a MasterSync wireless clock system, it’s possible.
Installing the wall clocks is a snap. Some models are even available with battery power, so you don’t need an electrical outlet nearby. Models are available in wall and ceiling mount in a variety of styles. Simply hang them where you need them.
The compact, lightweight wireless transmitter can be placed anywhere there’s an available electrical outlet. Position the GPS receiver where it gets a clear signal, connect it to the transmitter and turn the transmitter on. Visible indicators show the system is powered up and receiving signal, while a bright, clear digital display confirms the time that’s being broadcast. That’s all there is to it. Plug-and-play — it’s as simple as that!
The system’s operating frequency of 467 MHz is optimal for indoor transmission, providing reliable signal penetration of all types of building materials. This system is highly economical — a single transmitter with a standard antenna can cover up to 250,000 square feet, eliminating the need for repeaters or multiple transmitter units. Unlike old-fashioned wired systems, there’s no limit to how many wall clocks can synchronize with a single transmitter.
