Wi-Fi Digital Clock/Elapsed Time Indicator
with Code Blue Installation Manual
Introduction
Wi-Fi is a popular technology that allows an electronic device to exchange data or connect to the internet wirelessly
using radio waves. Wi-Fi and Simple Network Time Protocol (SNTP) are used to make installation and setup as
simple as possible. All you need to do is apply power to your precongured clock in an area where the intended
Wireless Local Area Network (WLAN) signal strength is sufficient.
Each Wi-Fi clock can be factory-congured to receive the precise time signal from your network server. They also
automatically correct for the Daylight Saving Time changes and require little maintenance. Wi-Fi clocks only require
synchronization twice per day using SNTP and create very little network trafc with staggered wake times. The electric
and digital models can be user-selected to synchronize at a desired frequency.
Network
Precongured Wi-Fi Clocks are plug and play on networks with Dynamic Hosting Conguration Protocol (DHCP).
A limited access point mode is also available for clocks that are not precongured at American Time as recommended.

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 completes an SNTP time sync, the clock will display and begin
keeping time.
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 Wi-Fi receiver. The 12- or 24-hour mode option is congured by the display settings of the Wi-
Fi receiver.
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, the time and the 12- or 24-hour format will be overridden by the Wi-Fi receiver settings
after it updates the time. 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 flashing.
Using the INCREMENT switch, set the desired hours for the preset time, then press ENTER. The minutes digits will
now be flashing.
Set the desired minutes the same way, then press ENTER. The seconds digits will then be flashing.
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.
nNote: 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.

Introduction
Wi-Fi Digital Clock/Elapsed Time Indicator
with Code Blue Installation Manual
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 Wi-Fi receiver 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 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 any Code Blue event, the Code Blue timer will start over from 00:00:00.
