Wire Cartell driveway sensors to Omnipro?

A year ago, just before my driveway was paved, I buried a pair of
Cartell sensors under it. The idea was to be prepared for connecting
up to my Omnipro alarm system such that I would get an audible "ding"
when a car enters the driveway but not when it leaves. But since I did
not have the money to do the whole job at the time, I just bought the
two sensors from a home automation installer. I explained my goal and
he sold me the sensors and explained where to bury them (15 ft apart).

Looking at my notes from a year ago, it seems the sensor closest to
the house is a CP-2 and the outer one is a CT-6 probe. I have the
wiring diagram for the CP-2 (5 wires), but not the CT-6 (3 wires).
Also, I have a note saying that the installer (who did not know I had
an Omnipro system) thought I would need a Cartell CF-2C controller to
make it all work.

So my questions are:
- What are the three wires from the CT-6 probe?
- Can I do without the CF-2C and use the Omnipro only? How?

Follow-on to the second question: how do I get an audible output from
the Omnipro? I don't have any speakers connected (except for the alarm
siren). I would like something simple, like a doorbell kind of
ding-dong, but it must sound different than my front door bell.

I suggest you physically check the actual wire from the probes to determine
what you have. As I understand it you can wire 2 CT-2XXX probes together to
provide directional output. If you are using 2 of CT units, you have do to
directional determination external to the Cartell units. IIRC Tom Morgan of
www.worthingtonsolutions.com has done this with an OmniPro. Check with him
about how he coded it. He may also be able to assist you in determining
which Cartell units you have.

Most of my Cartell installations have used a single sensor. In my
experience its good to know about departing traffic as well, and it doesn't
take long before you *know* if its incoming or outgoing.

To make noise from your Omni there are a number of options:
- Trigger a timed output to power a piezo electric sounder
- Trigger a timed output to power a relay which in turn triggers a more
civilized sounder
- Send an X10 output to a Chime or Universal Modules
- Post a message to the Omni consoles and then clear it, which cause the
console to beep 3 times.
There are more exotic ways to announce them (voice) but they get a bit more
complicated.

Couple of other thoughts. Regardless of how you announce the driveway
traffic, make sure you log it in the Omni. If nothing else you will know
when UPS really was there. Also have a means to turn off the announcement
for short periods. For example, if I have to leave at 0500 hours, I don't
want the announcement to wake the family.

- Close. CT's must be wired to a control board with no directional
ability (unless you used multiple probes and control boards and an
automation controller). 2 CP self contained units can tie the white
conductors to provide directional capability. The directional is
functional but no where near as useful as using the OmniPro (or other
automation controller) to make the decisions.

My notes are correct. The sensor closest to the house is a CP-2 and
the one furtherest away is a CT-6. Tom's site gives me half the
answer, because his solution uses two CP-2 probes. I need to know what
the three wires from the CT-6 are, and maybe I can figure it out from
there.

The probes are buried and I am not going to take one of them out. With
the Omni I should be able to set up different noises for incoming and
outgoing, if I should want to do so, right?

I have a CT2B manual in front of me, and it does not say which the 3 wires
are for, just how to connect them. Cartell literature clearly states that
the CT-6 requries a CT2 controller. A CT-6 cannot be connected directly to
an Omni or other security controller. This makes sense they are the just
outputs of the magnitometer, and not a contact closure. I checked and found
that the CT-2B controller and CP with 100ft of cable are the same price at
Worthingtons (http://www.worthdist.com/catalog01/p25.pdf) Since you do not
want to replace your probe, the CT2B is your only choice. From the CT-2
controller you get the contact closure to bring to the Omni. Once you get
a CT-2B installed, you can use what Tom has posted for the Omni end of
things(http://www.worthingtonsolutions.com/Documents/CP2PRO.PDF), just
deleting the power connection from the CT2 controller.

Yes. You could expand upon the ideas I gave you earlier or go to a aural
feedback instead.
