DESCRIPTION

The

american time

™

AllSync Plus clocks, with “Chameleon intelligence” 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.

The

american time

™

AllSync Plus clock is 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: 28.75-35 seconds starting at the 59th minute and 30th second. 12 hour correction: 13 minutes and 52

seconds-18 minutes and 8 seconds starting at 5:12:00 (am and pm). Note: This protocol switches off the run line during
the hourly correction.
