Operation
A. Send Tones Mode
B. Timed Relay Mode
When the clock time matches an event time in the current schedule (selected by dip switch 3) and
that day is set to “ON” or “Aon”, the
CTG-1A
will output the corresponding single, double or triple
bong or buzzer alert tone. The
CTG-1A
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-1A
. Similarly, while a contact closure
is made shorting pins 9, 10 or 11 to pin 12, the
CTG-1A
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. Terminals 6, 7 and 8 will operate the same as terminals 3, 4 and 5 but
are electrically isolated from terminals 3, 4 and 5 for switching a separate device.
To switch the
CTG-1A
from the current schedule to the second, use the MODE button to set the
CTG-1A
to the TIME mode, change the setting of dip switch 3 and use the MODE button to return
the
CTG-1A
to the RUN mode. The
CTG-1A
is now running the other schedule and will output the
single, double or triple bong or buzzer alert tones programmed in that schedule.
The Timed Relay Mode of the CTG-1A changes its operation to a clock controlled relay output
device, allowing the relay to be programmed to turn on or off at certain times of the day. Any day
of the week can be set to “off” (or no relay operation) using the day of week programming. When
the clock time matches an event time in the current schedule (selected by dip switch 3) and that
day is set to “ON” or “Aon”, the CTG-1A turns the relay on for a single event and turns the relay off
for a double or triple event. When the relay is turned on by a single event, the CTG-1A will close
terminals 4 and 5 (normally open) and open terminals 3 and 4 (normally closed). When the relay
is turned off by a double or triple event, terminals 3, 4 and 5 will return to their normal states.
Terminals 6, 7 and 8 will operate the same as terminals 3, 4 and 5 but are electrically isolated from
terminals 3, 4 and 5 for switching a separate device.
To switch the CTG-1A from the current schedule to the second, use the MODE button to set the
CTG-1A to the TIME mode, change the setting of dip switch 3 and use the MODE button to return
the CTG-1A to the RUN mode. The CTG-1A is now running the other schedule and will turn the
relay on and off based on the single, double or triple event times programmed in that schedule.
IMPORTANT:
While operating, the
CTG-1A
continuously checks the event time information stored
in memory. If a problem is detected, the
CTG-1A
displays “
EEE
” to indicate an error. Normal clock
function continues in the background. To clear the error, press any button and the
CTG-1A
will
return to normal operation.
