DESCRIPTION
The american time ™ AllSync Plus clocks are provided in round or square metal cases with glass crystals and bold, black
numerals and minute markers on a non-yellowing white dial. Stylish hour and minute hands are aluminum with a black finish
and a red sweep second hand.
AllSync Plus clocks are designed to work with multiple master clocks and correction signals. This unit is programmed to
identify the signal it receives from the master and operate as that style of clock. Changing clock operation from one style to
another is as easy as unplugging the clock from one system and plugging it into another. If needed, changing the placement
of 2 small jumpers on the circuit board can change the voltage required to run this clock from 120vac to 24vac or 24vac
to 120vac. This clock provides 15 minutes of backup run power without the use of batteries. If a power outage should last
longer than 15 minutes, the clock will synchronize to the master clock at the hourly and 12 hour correction cycles.
Correction Signals
Works on:
• Hourly correction: 7-9 seconds starting at the 57th minute and 54th second. 12 hour correction: 13-18 seconds starting at
5:57:54 (am and pm).
• Hourly correction: 24-28.5 seconds starting at the 0 minute and 0 second. 12 hour correction: 24-32 minutes starting at
6:00:00 (am and pm).
• *Hourly correction: 54-56 seconds starting at the 58th minute and 5th second. 12 hour correction: 10 pulses of 94-96
seconds starting at 5:05:00 (am and pm) and repeating every 2 minutes.
• Hourly correction: 24-26 seconds starting at 0 minute and 0 second. 12 hour correction: 25 pulses of 24-26 seconds
starting at 6:00:00 (am and pm) and repeating every 60 seconds.
• Hourly correction: 63-67 seconds starting at the 58th minute and 0 second. 12 hour correction: 14 pulses of 63-67
seconds starting at 5:06:00 (am and pm) and repeating every 2 minutes.
• *Hourly correction: 54-56 seconds starting at the 58th minute and 5th second. 12 hour correction: 12 pulses of 63-67
seconds starting at 5:05:00 (am and pm) repeating every 90 seconds.
*Note:
When switching between these correction protocols, you must use a different correction protocol to complete the transition.
The AllSync Plus clock needs to distinguish between hourly corrections before it can change correction protocols internally.
