Operation
Sound Output Specifications
Unplug the CTG-1 from power and turn DIP switch 1 OFF. Remove the shunt as shown in the
diagram above to change from 60 Hz to 50 Hz, or replace it to change from 50 Hz operation to 60
Hz. Power the CTG-1 back up and turn DIP switch 1 ON. Set the CTG-1 to the current time.
K. Changing the Power Line Frequency Setting
A. Bong Alert Tone
B. Buzzer Alert Tone
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 terminals 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.
