Warning:
To prevent electrical shock, do not apply electrical power to master, clock relays and clock wiring before
completing all wiring connections.
The AllSync Plus clock can run off either 24vac/60 Hz or 120vac/60 Hz. To change between the two different
supply voltages two jumpers must be set inside each clock. This setting is completed by American Time when
your clock(s) are built according to the part number ordered.
Caution:
Setting the AllSync Plus clock for 24vac and powering it with 120vac will damage the circuit board.

AllSync Plus Startup Routine
LED location on back of clock
The AllSync Plus clocks operate differently from their fixed clock protocol mechanical counterparts and from the
older AllSync clocks.
After power is initially supplied to the AllSync Plus clock run line the following will occur:
1. The clock will charge its internal backup power cell and undergo startup diagnostics.
Note: This may take from 1-9 minutes. During this charge period the clock will run through the start
up diagnostics indicated by the LED on the back of the clock and the clock hands will remain still.
2. The second hand will begin slow stepping (moving 1 second on the clock face for every 3 seconds real
time).
Note: This stage will last for approximately 3 minutes. While the second hand is slowly stepping the
LED on the back will flash green. The green flashing LED indicates the microprocessor is telling the
movement what time it is. The default time for the circuit board is 12:50. This is the time the
movement receives on startup and after extended power outages (greater than 15-20 minutes).
3. The clock will rapidly advance and the LED will turn solid red.
Note: The solid red LED indicates the clock circuit board has not received a 12 hour correction.
4. The clock will stop rapid advancement sometime between 12:50 and 1:15 as seen on the clock face
and begin running at the correct pace (1 tick per second).
Note: The rapid advancement of the hands may pause periodically for the clock to find its position.
Rapid advancement will continue shortly after the clock has completed its location check.
Note: Rapid advancement may last as long as 15 minutes. Total rapid advancement time depends on
hand location prior to startup.
5. When the time on the clock face reaches approximately 2:02, the clock hands will rapidly advance to
match the minutes on the master clock connected to it.
Note: If a master does not send a valid correction, the AllSync Plus clock cannot synchronize its minutes
to the master.
Note: The minute and second hands will be on time with the master after this rapid correction.
6. Approximately 5 minutes after the conclusion of the first 12 hour correction from the connected
master the AllSync Plus clock will rapidly advance to match the exact time on of the master (hour
hand will correct).
Note: The AllSync Plus clock is set up at the factory for clock code 01 (xx:57:54 – 8 second hourly
correction, 5:57:54 – 14 second 12 hour correction). If running a different clock protocol, the AllSync
Plus clock may require an additional 12 hour correction to recognize the different clock protocol. If this
is the case, allow 24 hours for the clock to synchronize.

Installation Introduction
General Operation
AllSync Plus accuracy
The AllSync Plus movement continually makes adjustments to its own internal clock. With each correction
received from your master clock it will make an adjustment to match the time on the master. For this reason,
the longer the AllSync clock is connected to your master the closer it will get to your master’s time. After
approximately 2 days the AllSync Plus clock should be ±1 second to the master system clock.
Movement corrections
The AllSync Plus clock has two primary yet completely separate parts: the circuit board and the movement. The
circuit board listens to your master and tells your movement, when asked, the time in its own language. The
movement will ask for the time 4 times a day at 2am, 8am 2pm and 8pm. For this reason if your master time
is changed, the AllSync Plus clock will not correct until it has both received a correction from the master and
reached one of its four daily correction times.
Note: The AllSync Plus clock(s) starts its internal clock at 12:50 when power has been removed from it by more
than about 25 minutes.

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.
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.
