Viking's model CTG-1 is a clock controlled tone generator designed to provide accurately timed bong alert
tones or buzzer alert tone sounds over an existing
paging system.
The CTG-1 can be programmed to output single, double or triple alert tones with up to 128 events in a 24
hour period. These bong/buzzer sounds are ideal for
indicating the start and end of shifts, break times,
lunch periods, etc. for factories, schools, or any busi-

Connect the CTG-1 between your phone system and your paging amplifier as shown in the diagram below. The factory
installed rechargeable 9V battery will maintain the clock time for over 8 hours.
IMPORTANT: The CTG-1 leaves the factory with the battery backup DIP switch turned OFF to avoid discharging
the battery during shipment. The battery backup DIP switch MUST be set to ON (see Programming section J) to
maintain clock time during a power outage.
Clock and Event Time Setting Buttons: Press
the + or -/CANCEL buttons to increase or
decrease time. The -/CANCEL switch is also
used to cancel an alert tone event when reviewing programming.
Alert Tones Programming Buttons: After setting an event time, press SINGLE, DOUBLE or
TRIPLE to program 1, 2 or 3 alert bongs/buzzer
sounds for that event time.
Secondary Button Functions While in the SET

A. Setting the Clock Time
1. Press the MODE button repeatedly until the SET TIME indicator lights.
2. Increase or decrease the clock time by pressing the + or -/CANCEL button until the desired time is displayed.
3. Leave the set time mode by pressing the MODE button.
Note: Either the + or -/CANCEL button MUST be pressed at least once prior to leaving the set time mode. The clock will then start to run the moment you leave
the set time mode, allowing you to synchronize the CTG-1 with your building clocks.
B. Setting the Day of the Week
Note: This step is only required if you want to turn off the Alert Tones on certain days of the week.
1. Press the MODE button repeatedly until the SET DAY indicator lights.
2. A flashing “A” indicates all 7 days of the week are “on” and today’s day has not been set. The day of the week has already been set if a flashing number
(1-7) and “on” or “of” are displayed.
3. Select today’s day of the week using the TIME (+ and -/CANCEL) buttons. As a general rule, Sunday is day 1 and Saturday is day 7. When today’s day of
the week is flashing on the display, set it by pressing the DOUBLE alert tone button. Today’s day number and “on” will now be displayed.
Note: The day of the week setting and turning the alert tones off on specific days of the week is a one time set up and does not need to be reset unless you
have experienced a brown out long enough to discharge the 9V battery backup (approximately 8 hours). To reset the day of the week and turn off tones on specific days of the week, you must power down the CTG-1, set DIP switch 1 to OFF, power up the CTG-1 and repeat steps 1-3 above. If you had alert tones turned
off on specific days of the week, repeat steps 1-4 in section C below. When finished, set DIP switch 1 back to ON.
C. Turning the Alert Tones On/Off for Specific Days of the Week
D. Setting Timed Alert Tones
1. Press the MODE button repeatedly until the SET EVENTS indicator lights.
2. Increase or decrease the event time by pressing the TIME (+ or -/CANCEL) button until the desired time is shown.
3. Move DIP switch 2 to OFF for bong alert tones or ON for buzzer alert tones (see Programming section J).
4. Press one of the single, double, or triple ALERT TONES buttons to program the number of alert tones you wish to output at the specific event time. A single,
double, or triple confirmation beep should be heard.
5. Repeat steps 2-4 for the remainder of your scheduled events.
Note: If more than 128 events have been entered, a long beep will be heard indicating that the event memory is full.
E. Reviewing and/or Cancelling Timed Alert Tones
1. Press the MODE button repeatedly until the REVIEW/CANCEL indicator lights.
2. Press one of the ALERT TONES buttons (single, double, or triple) repeatedly to rotate through the event times associated with that alert tone button. A red
LED at the bottom right corner of the time display will light to indicate a buzzer event time (versus a bong event).
Note: Event times are stored in the order of programming, not chronologically.
3. Press the -/CANCEL button to permanently cancel an event tone. A single acknowledgement tone will be heard. The next consecutive event for that
specific alert tone will then be displayed.
4. Repeat steps 2-3 as needed to remove the events to be cancelled.
5. When all events for a given alert tone have been cancelled, the display shows three dashes (- - -).
F. Adjusting Output Volume
1. Short pins 9 and 12 together momentarily. The doorbell sound will then chime once.
2. Adjust the volume control potentiometer (see Installation).
3. Repeat steps 1-2 until the desired volume is achieved.
G. Activating Contact Closure Alarm Tones
To activate different sounds, short the corresponding pins with a dry contact closure as
shown right (see Installation, section A). Note: The evacuation sound and siren will be
repeated continuously, as long as the closures are maintained.
1. Press the MODE button repeatedly until the SET DAY indicator lights. The current day of the week and “on” or “of” will be displayed. “on” = alert tones are
ON and “of” = alert tones are OFF for that day of the week .
2. Pressing the SINGLE button will toggle between flashing the day of the week and flashing “on” or “of”. The flashing portion of the display is the section that
can be changed.
3. With the day of the week flashing, use the TIME (+ and -/CANCEL) buttons to select the day of the week you would like to set to ON or OFF. When the
correct day of the week is displayed, press the SINGLE button to flash “on” or “of”. The day can then be set to ON or OFF by using the TIME (+ and
-/CANCEL) buttons.
4. Review your day of the week programming by pressing the SINGLE button until the weekday (1-7) is flashing, then increment through each day of the week
with the TIME (+) button and monitor each day for its on or off setting. Exit the SET DAY mode by simply pressing the MODE button.
When finished programming, press the MODE button until the LOCK indicator lights. In the lock mode, the time and alert tone keys will be disabled and the current time will be displayed with the colon flashing once per second.

Turn DIP switch 1 OFF. Unplug the CTG-1 from power. Pause a few seconds and then plug the CTG-1 back in. Push the CANCEL and SINGLE buttons at the
same time and release them. Repeat, and after releasing the buttons the second time a long beep will be heard indicating that the CTG-1’s memory has been
cleared. Turn DIP switch 1 back ON to enable battery backup. Note: After completing this procedure, it will be necessary to reset the clock time (see
Programming section A), and if enabled, the day of the week (see Programming section B) and alert tones on/off (see Programming section C).

When the clock time matches an event time and that day is set to “ON” or “A”, the CTG-1 will output the corresponding single, double or
triple bong or buzzer alert tone. The CTG-1 will also open terminals 3 and 4 (normally closed) and close terminals 4 and 5 (normally
open), allowing the capability of switching out the audio from the phone system and switching in the alert tone from the CTG-1. Similarly,
while a contact closure is made shorting pins 9, 10 or 11 to pin 12, the CTG-1 will output the corresponding sound (doorbell, evacuation
signal or emergency siren). In the case of the siren or evacuation signal, terminals 3 and 4 will open, and terminals 4 and 5 will close
and the sound will continue for the duration of the contact closure input. Terminals 3, 4 and 5 will return to their normal states at the end
of each doorbell tone. Note: Terminals 6, 7 and 8 will operate the same as terminals 3, 4 and 5 but are electronically isolated from ter-
minals 3, 4 and 5 for switching a separate device.
IMPORTANT: While operating, the CTG-1 continuously checks the event time information stored in memory. If a problem is detected,
the CTG-1 displays “EEE” to indicate an error. Normal clock function continues in the background. To clear the error, press any button
and the CTG-1 will return to normal operation. If the “EEE” display persists, contact Viking Technical Support at 715-386-8666.
