F. Adjusting Output Volume
Step 1.
Short pins 9 and 12 together momentarily. The doorbell sound will then chime once.
Step 2.
Adjust the volume control potentiometer (see Installation).
Step 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.
H. Locking the CTG-1 for Operation
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.
I. Clearing the Alert Tone Memory
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).
