times in quick succession as before. The LED will stop blinking when sound is restored to its
previous setting.
ADJUST TIMING (OPTIONAL)
The default timing for the CT-A1 is set at the control unit (see “Adjusting Sounder (Annunciator)
Time” on page 2). However, if a longer sounding time is desired for individual CT-A1’s, it can be
lengthened by turning the pot on the sounder’s circuit board counter-clockwise (CCW).
CONNECTING CT-A1 SOUNDER TO CT-2B CONTROL UNIT
See Figure 4.
Connect wires to CT-A1 first, then to the CT-2B.
At CT-A1, connect a wire to terminal “V.” At
CT-2B, test resistance as noted above and
connect to terminal 3.
At CT-A1, connect another wire to terminal “G.”
At CT-2B, test resistance and connect this wire
to terminal 8.
At CT-A1, connect a third wire to terminal “S” (for steady tone) or “P1” (for fast pulsating tone) or
“P2” (for slow pulsating tone). At CT-2B, test resistance and connect this wire to terminal 9.
NOTE: The three extra functional buttons on the CT-A1 (“ON”, “RESET”, “EXIT”) are non-functional
when used with the CT-2B. They should be ignored.
For using CT-A1 with a two or three-driveway system, see manual that came with CT-A1.
INSTALLING CT-11 SOUNDER
See Figure 1 on page 1. 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 8.
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 9.
INSTALLING AA-1 SOUNDER
See Figure 1 on page 1. Connect the RED lead to the terminal marked SON on the sounder.
Connect the BLACK lead to GND 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. 9. Twist the BLACK lead to the SHIELD wire and connect to terminal No. 8.

us
, there are some simple procedures you can follow. The vast majority of all
service problems result from a fault with the control unit and not from the probe.
Disconnect the probe wires from the control unit and perform the resistance tests listed in "CT-6
Probe and Wire Check-Out” on page 3. The resistance tests will determine the health of the probe
and wire.
If the probe reading indicates a bad probe, do not immediately dig it up. Rather, if there is a splice
in the line, locate it and cut the wire on the probe side of the splice. Then retest it. If the probe still
tests bad, go to the sensor probe itself and cut the wire one foot from the probe and retest it. If the
