connected to the momentary input terminals of the gate operator, typically the key pad input or RF
radio receiver input. The time adjustment for the relay adjustment "A" should be set at its minimum
setting (see “Adjusting Sounder (Annunciator) Time” on page 2). Longer relay time may be
necessary for those installations where the vehicle stops, then restarts near the sensor probe after
the gate is open.

In addition to tripping the gate operator, the CT-2BG can be used to trip a sounder inside the home.
Run a wire to the gate operator from the home and use the extra set of relay contacts (terminals 8
and 9, see Figure 1 on page 1) to trip the sounder inside the home. For more information, contact
technical support by calling
(800) 878-7829.

You will need two things to have a successful installation:
1.The manual for your home automation or security panel
2.A resistor (consult your manual for the correct size)
The CT-2B has a floating, dry relay contact.
Note:
Use the power supply that came with the CT-2B to power it rather than relying on the
home automation or security panel for power.
Use two wires to connect the CT-2B to a single zone on your panel. If your system’s contacts are
normally closed, use terminals 5 & 6 on the CT-2B. At your system’s panel, place a resistor between
the terminals in parallel (see your H.A. manual for resistor size).
If your H.A. contacts are normally open, use terminals 6 & 7 on the CT-2B and place a resistor
between the terminals in series (see your H.A. manual for resistor size)

It is advisable to check the sensor 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.
The resistance between the RED lead and the SHIELD, or the BLACK lead and the SHIELD should
be millions of ohms. The resistance between the SHIELD drain wire and earth-ground should be
millions of ohms.
While making measurements to the SHIELD drain wire, do not touch the bare wire or the
mulitmeter leads with your fingers as that will spoil the readings.
If a bad probe is indicated, it may be an improper wire splice (see "Splicing Probe Cable" on page
8). Before digging up the system, dig up the wire splice only, cut the wire on the probe side and
retest the system. If the bad readings still exist, cut the cable several feet from the probe and retest.
See "Splicing Probe Cable" on page 8 for proper splicing. Call
us
for further troubleshooting before
digging up the system.
