Impulse systems

An impulse system drives the connected clocks by 24V DC polarized impulses sent from a time base (master clock/master clock programmer or time-central).

The impulses can be sent either at 1/1-minute, -minute or 1/1 second intervals, depending on how the connected clocks show time.

The clocks are connected to the time base via a 2-wire cable. At installation the time displayed on the connected clocks is programmed into the master clock and the master clock then automatically by fast impulses sets the clocks to correct time.

At power failure the connected clocks stop running. When the power is back the clocks are automatically set to correct time with fast impulses.
