See Figure 2 on page 2. A proper earth-ground is essential. A proper earth-ground is established
by using an 8 foot copper or copper-clad ground rod driven deeply into the earth.
Use a ground wire of at least 12 gauge. Solder wire to ground rod and then clamp it. Tin the other
end of the ground wire and connect it to terminal No. 3 on the control unit.
SPECIAL NOTE
:
A galvanized ground rod will not give this system a proper ground. Use copper-clad.

The trip-test button, located center right on the circuit board, is a tool to evaluate most of the control
electronics and to help in setting the relay time. To test the control unit, a working probe must be
attached to terminals No. 17, 18, and 19 (see Figure 2 on page 2). If the probe is disabled or not
connected, simply connect a 500 - 1000 ohm resistor between the probe terminals No. 17 and 19.
NOTE: The TRIP TEST button will not work if the PROBE FAULT LED is lit (this indicates a disabled
probe).
Set the probe sensitivity potentiometer "G" to the halfway point, i.e., vertically up and down (see
Figure 6 on page 10). Push the TRIP-TEST button on and off quickly. DO NOT hold the button on.
The signal generated simulates that of a detected vehicle. No response indicates component failure
on the circuit board or failure of the power supply. It may be that the EXIT DELAY timer has not
timed out as well (the EXIT DELAY time may have been preset anywhere between 50 seconds and
15 minutes (see “Adjusting CT-A1 Exit Delay” on page 9).

The annunciator relay has a second set of Form “C” relay contacts on terminals No. 11, 12, and 13.
These contacts may be used to trip an alarm panel, trip a dialer, trip a line carrier interface, trigger a
transmitter or trip a door bell. Potentiometer “F” controls the relay time of these contacts.

See Figure 2 on page 2. The CF-2C has a floating, dry relay contact that can be used in
conjunction with any security or home automation (H. A.) system.
Two things will help you have a successful installation:
1. The manual for your home automation or security panel
2. A resistor, if required (security or H.A. system manual will tell you if a resistor is required)
Note:
Use the power supply that came with the CF-2C to power it rather than relying on the H.A.
or security panel for power.
Hook the CF-2C to two zone inputs on your security or H.A panel. If your system’s contacts are
normally closed, use terminals 11 & 12 on the CF-2C. At your system’s panel, place a resistor (if
required) between the terminals in parallel (see system manual for correct resistor size).
If your security or H.A. contacts are normally open, use terminals 12 & 13 on the CF-2C and place
a resistor (if required) between the terminals in series (see system manual for correct resistor size).

It is advisable to check the CT-6 probe assembly before and after installation in the earth. Use a
good multimeter. With the probe wire disconnected from the control unit, measure the resistance
between the RED and BLACK leads. It should read between 500 and 800 ohms for a single probe.
Additional probes on the system will add approximately 620 ohms each. The reading should be
stable with zero fluctuations.
