Master Clock

The Telecor Master Clock is a precision clock that provides timing signals to a network of secondary clocks ensuring that all clocks display identical time.

In addition to providing time correction and synchronization, the master clock provides the ability to control the operation of external devices such as bells, tone signals, and external relays throughout the day based on pre-scheduled times that are programmed into the master clock.

Timekeeping precision to ensure all clocks display identical time accurately.

Built-in event scheduling provides the ability to activate remote devices to transmit tones or activate bells to signal class changes in educational facilities or shift changes, breaks, etc. in factory environments.

Multiple time schedules can be programmed on the master clock and enabled for the activation of different events on different days. Schedules can be edited, enabled or disabled by the end-user. In addition, events can be activated by the front panel controls or by push buttons wired to available input points on the Master Clock.

Events can include a variety of elements such as bells, tones, activating relays and auxiliary devices, coded messages and playing audio such as announcements or music.
