Time Base: In the "Set Up Clock" screen, click this pull down menu to select the CTG-2's time base. With "Internal
Clock" selected the CTG-2 will base its time off its internal crystal controlled (quartz) real time clock with an accuracy
of approximately 2 ppm which is +/- 63 seconds per year without atomic clock sync.
With AC Line 50 or 60
Hz selected the CTG-2 will base its time off the AC voltage powering the unit. The clock accuracy will then follow the
power company fluctuations. This can be useful for matching the CTG-2 time to existing AC powered clocks.
Time Zone: Clicking this pull down menu will allow you to select the correct time zone for your region.
Set Clock: Clicking this pull down menu will allow you to select the method used for setting the CTG-2's internal clock.
Selecting "Manual" will allow you to manually adjust the time and date parameters then click "Set" or "Upload" to set
the time and date in the CTG-2's internal memory. Selecting "Use PC Time" will load the current time and date from
your PC into the "Clock Time" parameters then click "Set" or "Upload" to set the time and date in the CTG-2's internal
memory. Selecting "Sync to ACTS" will allow you to force an Atomic Clock Sync from your PC by clicking "Set" or
"Upload". This process will take approximately 30 seconds. The current time and date will then be loaded into the CTG-
2 and displayed under "Clock Time".
ACTS Phone Number: "ACTS" is the abbreviation for "Automated Computer Time Service" provided by NIST (National
Institute of Standards and Technology). This field is factory loaded with the typical phone system line access number 9
and a comma (1 sec pause) then 1 and the 10 digit number for the ACTS. This number can be user programmed with
up to 50 digits, allowing the use of calling cards, etc. to reduce long distance charges. The telephone number for ACTS
is: 1-303-494-4774.
ACTS Sync: Clicking "ACTS Sync" will activate a forced Atomic Clock Sync. The internal modem in the unit will seize
the phone line, speed dial ACTS and download the current time and date. This process will take approximately 30 sec-
onds. The current time and date will then be loaded into the CTG-2 and displayed under "Clock Time".
Security Code: This is a programmable 6 digit touch tone code for entering remote touch tone programming. This
code is to be entered after the CTG-2 has answered the line and given a confirmation beep.
Daylight Savings Time Enabled: Check this field to enable
automatic daylight savings time correction. The CTG-2's internal
clock will then be advanced 1 hour at 2:00 AM of the Starting
Sunday and dropped back 1 hour at 2:00 AM of the Ending
Sunday.
Daylight Savings Time: In the "Tools" pull down menu. This
screen allows you to program the starting and ending month and
Sunday for the automatic change to Daylight Saving Time. Use
the pull down menus to select the starting and ending month and
Sunday then click "Upload" to send the data to the CTG-2. The
CTG-2's internal clock will then be advanced 1 hour at 2:00 AM of
the Starting Sunday and dropped back 1 hour at 2:00 AM of the
Ending Sunday. (top right)
Triggers: Clicking the "Triggers" button in the "Event
Programming" section will open the "Set Up Triggers" program-
ming screen where you can enter/program the parameters for
Trigger Inputs 1-4 such as which wave file to play, Contact
(N.O./N.C.), Trigger Mode (Alt Action/Activate Only), Play Count
(1-99 or Continuous), Volume setting, Type (Mom / Cont) and
Playback Mode (Interrupt/stack).
Trigger 1: Evac Signal.wav (ANSI S3.41/ISO 8201
Audible Emergency Evacuation Signal)
Trigger 2: Attack Wail.wav
Trigger 3: Alert Siren.wav
Trigger 4: Buzzer 4sec.wav
