Tone Generator & Bell Controller

Accurately synchronise your existing bell system with the clocks on the wall or individually with a Tone Generator & Bell Controller. Alternatively, and if you already have a PA system, coordinate tones and/or music to broadcast at predetermined times, again synchronised with your clocks.  Easy to install scheduler software allows you to maintain order and eliminate confusion and chaos within your facility when the clocks and bells are in sync.

General

Our tone generator is used to activate a bell or buzzer system . It also has an audio out connector that lets you interface with an existing PA system in order to play a variety of MP3 files over the public address system at a scheduled time.

A number of schools have a poorly or non-functioning existing wired bell system. Existing systems commonly also have independent time controls (some none at all) that activate the bells completely out of sync with the clocks on the wall. The tone generator solves this problem by synchronising the old bell system to GPS time. This is accomplished by using the tone generator’s contact closure to activate the bell system at a precise scheduled time. Typically existing bell systems have all the bells wired to a master bell controller. These old systems fail over time. It is a simple procedure to remove the old controller and replace it with the tone generator.

The tone generator receives its time from the KRONOsync transmitter. The transmitter receives its time from either GPS satellites or from the internet via Network Time Protocol, NTP. Both time sources are simple and produce accurate time. The transmitter then broadcasts this time throughout the facility. The broadcast enables clocks, message boards and tone generators to receive accurate time.

Once the tone generator has the accurate time it can turn on or off its contact closure based on a schedule. The schedule is stored on an SD card within the tone generator. The SD card is programmed using the scheduling software that ships with tone generator. The scheduling software allows you to easily schedule the day of the week and time of day in which the contact closures will open and close.

The contact closures can control virtually any electrical device. Typically in a manufacturing environment it is used to turn off and on buzzers. Basically you can turn on or off any device at a scheduled time.

The other function of the tone generator is to provide an audio in source for an existing public address system. In these cases a customer may have in place a PA system and would like for tones, prerecorded messages or music to play over the PA speakers at a scheduled time.

To accomplish scheduled audio events to occur over a PA system the tone generator should be located close to the PA system. Cable the audio out port on the tone generator to an audio in port on the public address head end. The scheduling software comes with a number of MP3 files available for your use. Included are files such as bell tones, chimes, and chirping birds to name a few and you can add your own MP3 files also.

There is no adjustment needed for the spring or autumn time change for daylight savings time. The reason is because the adjustment for daylight saving time occurs at the transmitter; the transmitter will broadcast the adjusted time.

The tone generator receives it time from the KRONOsync transmitter, the bell schedule resides on the SD card located on the tone generator and the contacts are wired to a bell, buzzer or a bell system.
