INSTALLING CT-A1 SOUNDER (replacement sounder for FC-9, CT-8 and CT-8A)
See Figure 5.
Connect wires to CT-A1 first,
test resistance, then connect to
the CF-2C.
At CT-A1, connect a wire to
terminal “V.” At CF-2C, test
resistance and connect this wire
to terminal 6.
At CT-A1, connect a wire to
terminal “G.” At CF-2C, test
resistance and connect this wire to terminal 15.
At CT-A1, connect a wire to terminal “S” (for steady tone) or “P1” (for fast pulsating
tone) or “P2” (for slow pulsating tone). At CF-2C, test resistance and connect this wire to terminal 14.
At CT-A1, connect a wire to terminal “E.” At CF-2C, test resistance and connect to terminal 9.
At CT-A1, connect a wire to terminal “R.” At CF-2C, test resistance and connect to terminal 10.
At CT-A1, connect a wire to terminal “M.” At CF-2C, test resistance and connect to terminal 8.
INSTALLING CT-11 SOUNDER
See Figure 2 on page 2. Please read the instructions in the introduction. First make the
connections at the CT-11 plate and then to the control unit as follows:
Connect one colored wire to the terminal marked “−”. At the control unit, test the resistance as
noted above. Then proceed to connect this wire to terminal 15.
Connect another colored wire to the terminal marked “+”. At the control unit, test the resistance as
noted above. Then proceed to connect this wire to terminal 14.
INSTALLING AA-1 & CT-11 SOUNDERS
See Figure 2 on page 2. Connect the RED lead to the terminal marked SON (or +) on the sounder.
Connect the BLACK lead to GND (or —) on the sounder. At the control unit, test the resistance RED
to BLACK as noted above. If resistance proves correct, at the control unit connect the RED lead to
terminal No. 14. Twist the BLACK lead to the SHIELD wire and connect to terminal No. 15.

See Figure 6. The exit-delay time (potentiometer “C”) can be adjusted from 50 seconds to 15
minutes. To determine the exit delay time, first remove the RED probe wire from terminal No. 17.
This will put the CF-2C into PROBE FAULT mode (see page 6). When the exit delay timer times out
the annunciator relay will constantly cycle on and off.
To activate the exit delay timer on an installed CT-A1 annunciator, press the exit delay button on
the annunciator plate. If other devices are being used to activate the exit delay timer (such as an
alarm panel, etc.), take a wire and short the terminals between No. 9 and No. 15 at the CF-2C
control panel. Doing this for 2 seconds will trigger the timer. When the timer is activated, the
annunciator relay will stop cycling.
Measure the time from when the relay stops and when the relay begins cycling again and you will
know the exit delay time. For longer exit delay time, adjust the potentiometer marked “C” clockwise
and repeat until the desired time is achieved. Re-attach the RED probe wire to terminal No. 17 when
finished.
