Operation Control Station Clock/Timer
The Digital Clock/Timer is a six digit multi-function clock/timer. This clock functions in a 12 or 24 hour mode which is
updated by the SiteSync IQ wireless clock system.
When combined with the ATSTCS Control Station, the clock can also be used as an up or down counting elapsed timer. The
elapsed timers can be started, stopped, resumed, and reset. Both timer modes have a programmable preset value. When the
timer reaches the preset value, a two second audible alarm sounds from a speaker in the control station. The clock/control
station contains a Code Blue count-up timer that overrides all other modes of operation.
Indications
Audible Alarm - Used to indicate that a timer is done counting.
6 Digit Clock Display - Used for displaying time of day, displaying counter value, for setting time, and setting up or down
counter preset values.

Operation
Powering Up
u
Before applying power, place the SET/RUN switch to the RUN position and the UP/DOWN/CLOCK switch to the CLOCK
position.
v
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.
w
If using an SQA261RSAES, this clock will only copy what is displayed on the SQA261RSAEA it is connected to. If power
is turned off to the master clock, this clock will also turn off.
Setting Time
Setting of the time is not needed for the digital clock or 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 control station will allow the user to set a 12 or 24 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 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 up the 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.
u
Set the UP/DOWN/CLOCK switch to the UP position.
v
Set the SET/RUN switch to the SET position. The hours digits will be ashing.
w
Using the INCREMENT switch, set the desired hours for the preset time, then press ENTER. The minutes digits will now
be ashing.
x
Set the desired minutes the same way, then press ENTER. The seconds digits will then be ashing.
y
Set the desired seconds the same way, then press ENTER. The display will then ash donE.
z
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 99:59:59.

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.

Important 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 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 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.

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 120vac power is lost. If each in a series of 120vac 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 120vac power from the Digital Clock/Timer once per year for at least four hours.
nNote: There is no 9v battey in the SQA261RSAES clock. Only the SQA261RSAEA clock it is connected to has a battery.
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 866-748-3796.
