The KRONOsync transmitter is at the heart of the Innovation Wireless clock system. This powerful transmitter has been providing K-12 schools with synchronized school clocks, hospitals with maintenance free clocks and manufacturing/business with accurate wall clocks for years.

The KRONOsync transmitter operates on a frequency band of 467 MHz. The key attributes of this frequency band is its reliability and complete coverage. The 460-470 frequency bands has traditionally been used in paging applications because of its reliability.

A wireless clock system is a paging application. The transmitter broadcast or pages the clocks with the time code so that all the clocks tuned to the frequency can receive the time code and update their electronic quartz movement thereby ensuring that the clocks are always accurate.

Our standard clocks have become the industry standard for school clocks when a school is in need of sync clocks. These clocks operate on two D cell batteries and receive their time from the KRONOsync transmitter. They receive an accurate time update everyday 4 hours. Additionally, they automatically adjust for Daylight Savings Time in the spring and fall.

The KRONOsync transmitter broadcast can provide a broadcast area of appromiately 300,000 square foot area. If you are unsure about the square footage of your facility this is not a problem. One of our knowledgeable sales people can determine what will be needed to cover your complete facility. We cover complete campuses, multiple buildings or single high rise buildings.

The KRONOsync transmitter can be outfitted with an external antenna in order to provide coverage in a campus setting. The antenna size is small enough so that it is ascetically looking and suitable for any rooftop. The transmitter itself must be located within the building where it is protected from large fluctuations in temperature and humidity.

When the coverage area is larger than 300,000 square feet you also have the option of using a repeater to provide the additional coverage. By using repeater (s) or external antennas we can ensure complete coverage of your facilities.

The KRONOsync repeater has 5 watts of power and will add of about 250,000 additional square footage of coverage. The reason the repeater does not achieve the same coverage area that the transmitter achieves is because the repeater must be placed within the coverage area of the transmitter in order to repeat the signal. The result is that the signal will overlap to a certain point.

Our engineering of the transmitter makes for an extremely simple installation. The transmitter has two sources of time to choose from. One option is to retrieve time from GPS satellites. This option is very simple just plug the GPS receiver into the back of the transmitter. The receiver itself is no bigger than a small donut. The receiver comes with a mounting bracket providing you with different mounting options. It has suction cups on it so that it can be mounted directly onto a window. It also has screws so that it can be screwed into a permanent structure outside and it comes with a U bolt so that it can be mounted to a pole.

The second option to get time into the KRONOsync Transmitter is via your computer network via NTP (Network Time Protocol). This is also a very simple process whereby our NTP receiver is connected to the back of the transmitter and to the Ethernet network. Either GPS or NTP will provide the clock sync necessary so all the clocks display accurate time.

Once the transmitter has the time source the transmitter will broadcast the time code immediately throughout your facility. The only step needed on the clock side is to put batteries into the battery operated clocks and they will sync with the transmitter and display accurate time. The LED Digital Display Clocks will receive their time instantly when they are plugged into an electrical outlet.

The KRONOsync transmitter is the most powerful transmitter on the market and is the heart of our clock system. It can provide complete coverage from a single building to multiple buildings or a complete campus.
