Operation Installation Description
Operation
Powering Up
Before applying power, place the SET/RUN switch to the RUN position and the UP/DOWN/CLOCK switch to the CLOCK position.
Apply power to the unit. The displays may rotate during the power on self test and then a version number will appear for a few
seconds. Once the receiver inside the clock receives a signal from the SiteSync IQ system controller, the clock will display and
begin keeping time. At rst startup the clock may display a time such as 1:00:00 until it receives the rst time update from the
SiteSync IQ system controller. This should only take a few seconds, after which the correct time from the SiteSync IQ system
controller should appear.
Setting Time
Setting of the time is not needed for the digital clock or timer control station. The time information is automatically updated
by the SiteSync IQ system controller. The 12- or 24-hour mode option is congured by the display settings of the system
controller.
The ATSTCS timer control station will allow the user to set a 12- or 24-hour mode and time when the SET/RUN switch is in the
SET position. However, as soon as the SiteSync IQ system controller updates the 12/24 hour mode chosen, the time will be
reset to the time sent by the SiteSync IQ system controller and the 12/24 hour mode congured in the system controller. Set
the SET/RUN switch to the RUN position and the UP/DOWN/CLOCK switch to the CLOCK position to return the clock display.
Setting the Up Counter Preset Time
If you want to use the alarm and hold feature with the UP timer, you will need to set a preset time for the UP timer.
Set the UP/DOWN/CLOCK switch to the UP position.
Set the SET/RUN switch to the SET position. The hours digits will be ashing.
Using the INCREMENT switch, set the desired hours for the preset time, then press ENTER. The minutes digits will now be
ashing.
Set the desired minutes the same way, then press ENTER. The seconds digits will then be ashing.
Set the desired seconds the same way, then press ENTER. The display will then ash donE.
Set the SET/RUN switch back to the RUN position.
Note: A preset of 00:00:00 allows the digital clock/timer to be used as a standard elapsed timer with a maximum elapsed time
of 30:59:59.

Operation Installation Description
Code Blue
Description
The Code Blue feature provides an override which forces the clock into a special count up elapsed time mode. No matter
which of the three normal functions is being displayed, Code Blue input will cause the unit to begin counting elapsed time
from 00:00:00. All other functions of the unit continue to operate in the background during a Code Blue.
Operation
A Code Blue is initiated by applying a signal ranging from 12vac/vdc to 30vac/vdc to the K2+ and K2- terminals. See the
sample wiring diagram below for more detail.
The Code Blue timer is the highest priority function of the clock/timer while in the run mode. No matter which of the 3 normal
functions is being displayed, the Code Blue input will cause the clock to begin counting up elapsed time from 00:00:00.
The Code Blue timer can be stopped and the time held for viewing by pressing the START/STOP button on the ATSTCS switch
panel. The Code Blue timer cannot be restarted from the switch panel.
To reset the clock back to normal operation, the RUN/SET switch must be set to the SET position momentarily and then
returned to the RUN position.
All other functions of the clock continue to operate in the background during a Code Blue. Time of day and time corrections
from the SiteSync IQ system controller will not be affected. The standard count up timer and the count down timer will
continue as well. However, if one of these timers is switched on for display when a Code Blue occurs, that particular timer
will be reset when the clock is reset back to normal operation.

Code Blue
OperationInstallationDescription
Importan Considerations
The ATSTCS must be in the RUN mode for Code Blue to override.
The 12vac/vdc to 30vac/vdc signal that starts the Code Blue timer originates from equipment external to the Digital Clock/
Timer. The external equipment usually employs a switch device (i.e., a relay contact) to apply this signal. That switching
device is often referred to as the Code Blue contact.
The Code Blue contact does not have to open before resetting the Digital Clock/Timer back to normal operation, but must
be opened before another Code Blue can occur. The transition from no voltage to applied voltage (across the K2+ and K2-
terminals) initiates a Code Blue.
If the Code Blue contact opens and closes again before the Digital Clock/Timer is reset back to normal operation, the Code
Blue timer will start over from 00:00:00.
If a power failure occurs during a Code Blue and the back up battery is in place, and the Code Blue contact is still closed
when the power returns, the Code Blue timer will start over from 00:00:00. If the Code Blue contact is open when the power
returns, the Code Blue timer will continue counting the elapsed time including the time while the power was off.
If a power failure occurs during a Code Blue after the Code Blue timer has been stopped for viewing, and the Code Blue
contact is still closed when the power returns, the Code Blue timer will start over from 00:00:00. If the Code Blue contact
is open when the power returns, the elapsed time where the Code Blue timer was stopped prior to the power failure will be
displayed.

Operation Installation Description
Operator Maintenance
Cleaning
Occasionally the Digital Clock/Timer and the Control Station will need to be cleaned. Dampen a soft, nonabrasive cloth with
alcohol or a mild detergent. Do not use abrasives or solvents! Gently wipe the exteriors of the units with the cloth.
Battery Maintenance
The Digital Clock/Timer uses a single 9vdc Ni-Cad battery rechargeable via an on board charger. This battery retains the time
of day and timer counts when AC power is lost. If each in a series of AC power losses occur for a similar length of time, the
battery can be conditioned to provide only that amount of backup capacity. This phenomenon is called “memory” effect. The
Ni-Cad battery’s “memory” can be erased by deeply discharging the battery and recharging it.
It is recommended that the operator remove AC power from the Digital Clock/Timer once per year for at least four hours.
System Maintenance
The Digital Clock/Timer and ATSTCS Control Station have been manufactured for years of dependable, reliable use. However,
to assure the reliability of this product, it is recommended that the Digital Clock/Timer be tested at least every six (6) months
with the Control Station and Code Blue contact for operation in accordance with wiring congurations used.
WARNING
Replace the battery only with a 9v Ni-Cad
battery. Do not replace with a regular (primary)
9v transistor battery (i.e., zinc carbon battery,
alkaline battery)! An incompatible battery may
leak or explode, causing equipment damage and/
or personal injury! If battery must be replaced,
contact American Time at 800-328-8996.
