Alright, I tried my best to comprehend the installation of this sensor using the shock sensor's harness to tap into. I have searched and have found out alot of different things I am confused with. First, I read Suspended's How-To and found out that none of the wires on the AU94T and shock sensor is backwards. I also looked at the way to tap into different sensors with diodes, but there is a looped green wire on my shock sensor. I even searched the internet and they said I don't even need diodes, I can just twist the trigger wires because my alarm is a multiplex. Could somebody tell me how to wire this into my 791xv. Thanks for all the info so far Suspended and I didn't use a relay on my domelight , hope this was safe.

 

the au94t isnt made by DEI, and are you talking about the motion sensor?

also, what color DEI shock sensor are you using,.... the black or see through one?

 

The title was just to state I was using the Crime Guard AU94T with a DEI shock. The shock I got is the clear one.

 

Off of the shock sensor 3 pin plug harness there should be a green wire that is cut at one end and looped at the other. Connect your trigger to that green lead that is cut free. It should be a (-) input.

I do not recommend doing dome light supervision without a relay.
The dome light supervision output H1/9 black/white is a 200mA output, that's less then 1/4 amp.
Page 19...
Connect this wire to the optional domelight supervision relay as shown below:
IMPORTANT! This output is only intended to drive a relay. It cannot be connected directly to the
domelight circuit, as the output cannot support the current draw of one or more light bulbs.
H1/9 BLACK/WHITE (-) 200 mA domelight supervision output 94

 

Who do you believe, the guy that has 2 years experience and can't remember the last time he installed a 791 if it was 200mA output or a real ground output, or fcm, the guy that has 30 years experience? Yeah listen to fcm.

The au94t is a motion/proximity sensor.

Unplug the DEI shock sensor and toss it in the trash. Plug the AU94T into the shock sensor harness. Adjust it according to the instructions in my FAQ.

On some of the AU94T's, the blue and green pin positions were reversed when compared to the DEI sensor pins.

 

Assuming the wires of the AU49T are in the same position, when you replace the DEI shock sensor with AU94T (or AU49TM), do you:

A: cut the green wire and connect the sensor's side of the green to the sensor's blue (and leave the green wire from the alarm side free)?

Or,

B: connect Blue/Green of the sensor straight up to the Blue/Green wires of the DEI alarm (Blue to Blue, Green to Green).





note: as suspendedHatch said, it would be better to get power from the orange (-) ground when armed wire from the DEI alarm. I was just too lazy to draw it

I bought the AU94-TM advertised as a CrimeStopper, but it came in a generic box (no brand name), with instructions by Omega Research and Development, Inc.
This is what the manual shows:

This is what pg 32 of the DEI alarm manual shows:


If you wanted to add another sensor (like a AU94TM/AU94T) to the shock-sensor,
It would look like this:

What alarm do you have?

On the newer DEI shock sensors the blue and green wires are already looped together. Basically it all depends on how you want your triggers setup. Both the blue and the green wires are multiplexed inputs so both of them have a warn, and a full on. According to your manual there both zone 2 but on mine they have different zones. Basically you can hook the sensor up in your "Setup A or Setup B" both will function the same exact way. I would use setup A and leave the green wire off to be used for another sensor later down the road.

 

Thanks White Smoke... It all makes sense now

 

If you ground it to the chassis as opposed to the orange wire, the sensor will always be on. If you leave your alarm on for a week or so w/out driving it, it will drain the battery.

There is more then enough current on the DEI alarms orange, ground out when armed, to supply the radar sensor and the starter cut relay.

However I do agree that you should not use the red power lead for the alarms impact sensor, unless you are not using the impact sensor. 94

 

As I said I would not use the orange wire because you already have a power and ground what will be killed when the alarm is not active (and when remote started for that matter).

EDIT: Use orange wire. lol

I know it's been a while since I did one but as I remember it, both power and ground for the impact sensor are present even if system was turned off, and it was the trigger input that the system "ignored", [along with ign. input] when in remote start mode. 94

 

Hey guys, I'm getting conflicting information.

White Smoke, you say to don't use the orange for (-) power when <U>replacing</U> the DEI shock sensor, because the provided (-) power black sensor output lead is only active when the alarm is armed.

suspendedHatch and fcm say that the black sensor output lead is always active regardless of if the alarm is armed or disarmed.

So who is right? I'm using a Viper 5900. Is it possible that the newer DEI alarms don't always power the sensor, when the older ones did? I guess the only way to really find out is to check the voltage across the red / black wire, when arming and disarming the system.

That is what I would do, meter the black and red leads with alarm disarmed, as I said I remember them being "live" at all times, but that may have changed on the newer units.
We always used the orange for ground on prox sensors we added to alarms. 94

BTW, let us know what you find out.

 

fcm and suspended are correct. the shock sensor harness has 12v constant and a ground at all times. you can plug in the shock sensor and shake it and see the led illuminate at anytime whether the alarm is armed or not. as far as your new sensor goes if you're replacing the dei shock sensor you can use the power leads in the shock sensor harness if you want it to have power all the time. if you want it to get power only while the alarm is armed then use your 12v constant in the dei shock sensor harness and the orange ground when armed wire for ground.
if you're keeping your dei shock sensor and adding your new sensor then get 12v from your 5900's main harness. if you want it powered all the time get ground in the main harness also. or use orange ground when armed if you only want it powered when the alarm is armed. and i personally would get 12v constant in the main harness either way.
now as far as the trigger wires go, you should have a free green wire in your dei shock sensor harness that you can hook your new sensors trigger outputs too.
I HAVE NO EXPERIENCE with the new sensor you have so you should read the instructions or listen to fcm or suspended on whether or not you need to diode isolate its outputs from each other. i hope this helps and good luck.

There is noting wrong with hooking the black wire up to the orange ground wile armed wire, I just didn't believe it was necessary. Maybe I checked mine out wrong, I will go over it aging this weekend and report back.

You do not need to diode isolate the triggers with this setup.

 

a 50.5x has a built in shock sensor. it is possible that its twin sensor ports work different then the norm. as they are bitwriter controllable as to what icon shows up on the remote and such. the alarm in ? from what i read was a 5900.

 

I'm pretty sure the shock sensor on the 50.5x is not built into the brain (if that's what you were saying). Mine came with an external one and has the 4pin shock sensor harness just like the 5900.

Like I said I am going to double check the power output on mine this weekend. Mine very well could be different then yours so just meter the red and black wires to be sure. If there always hot then use the orange wire

 

I checked mine out. The shock sensor is Always being powered, even when the system is disarmed. This is for a Viper 5900.

I'm not positive, but I believe the Viper 5900 and Clifford 50.5X are the same thing in a different package. These four alarms have the same exact manuals, except for minor changes on the brand names. Even the Clarion, which is not owned be DEI has the same thing.

Alright, Hatch and I win, and it means DEI has not changed how they power the impact sensors on there lineup of alarms. for everybody.94

Hmm...looks like I've got to re-wire my AU-94tm sensor. I just hooked it straight to inplace of the shock sensor. But I can't imagine it using that much power, just as the shock sensor didn't use much power.
