I have an asianwolf 8000RS (scytek 5100RS) in my car. The alarm has a dual stage shock sensor which I think is a waste to even have. Anyways, I want to tie in a glass break sensor into the shock sensor. I know I have to diode isolate. First off, would it be ok to simply tie both power wires from those sensors together, or should I run a relay for the glass sensor? If I need a relay please explane how to hook it up. Also, on my alarm I can disable the shock sensor whenever I want (for instance if we are having a bad storm). Im assuming this would then also disable the glass sensor because they would be tied together correct? My last question is.... Are sensors on alarms bypassed when the vehicle is remote started? Thank you in advance for the responses.

I would suggest powering the additional sensor with an independent constant fused +12V. The power coming from the small plug is typically designed only to handle the power requirements of the impact sensor. If you are using the 506T it consumes less than 1ma of current so you should not need to worry about current draw.
As far as the bypassing of sensors, yes remote start systems typically turn off the shock sensor while running under remote start so what you are suggesting should work perfectly fine.

my glass sensor is made by scytek. It has 3 wires: red, black and blue. You said to use a relay for the power wire. So how exactly would I run that? Also, could I possibly run the ground wires together? I know to run the blue trigger wire to the full alarm wire from the shock sensor. Another problem I have is that the mic wire is only 2 feet long, so where would be a good place to mount the mic?

1. I did not say to use a relay.
2. Yes running the ground wire to the same location as the alarm's ground is fine.
3. Mic placement would be determined by placing the mic in different locations throughout the interior testing at each location to determine the most efficient spot.
I looked through Scytek's accessories site and they do not list the installation manual for the glass sensor but I would imagine it does not draw too much current so a constant hot should work fine. Also, maybe someone should let them know that it is an 'impact' sensor, not "in pack".  ------------- Installer, IT support, and FFL. I need less hobbies.

My shock sensor has 4 wires: red, black, blue, and white. My glass sensor has 3 wires: red, black, and blue. Im assuming the blue wire on the shock sensor is the full alarm trigger and the white wire is the warning chirps correct? Since my shock sensor goes off way too often (accidently) I was thinking of cutting the blue wire that way the shock sensor only has warn away chirps. I was then going to wire the glass sensor's blue wire to the blue wire going to the brain therefore I wouldnt need to use a diode. Would this work?

if you dont use the impact sensor and cut the blue to wire up the glass sensor, you dont need a diodeon that wire. as fot thew others, if u are branching them off, they all need to be diode isolated.

Does the Scytek system not have a wire or additional triggers ? I know the Compustar system do, this way you do not have to wire this into the existing sensors.

The only un-used port I have left is the scynet port.

just tap the red to red and black to black and blue to blue no need to diode. There is enough juice to run both. I've done it before on those.

Lets forget about the glass break sensor for a minute. I have a 2 stage single adjustment shock sensor. The blue wire im guessing is the full alarm wire. The white wire im guessing is for the warn away. What I want to do is only have the warn away working, thus I will have to cut the blue wire. But what I am worried about is how to wire the shock sensor then. If I keep the white wire connected, when I have a light impact on the car, the warn away chirps will sound. But if there is a hard impact, the shock sensor will want to give off the full sound alarm, but since that wire is cut, that wont happen. What I want to happen is no matter if its a light or a hard impact, I only want the warn away chirps to sound. So in order to do this would I have to first off cut the blue wire running from the sensor to the brain. Then take the blue wire on the sensor side and diode it to the white wire?

Why not adjust your shock sensor correctly...and leave the blue wire intact. Just a thought.

Because its either too low to sound on an impact or too high that it sounds all the time. Its a pain to adjust it and they give false alarms. I just want a simple warn away chirp. So how can I do that?

You anwsered your own question in you last post. I'm just curious if your an installer why did you get the skytek ? IMO those are cheap alarms.

they are reliable alarms. Everyone knows that shock sensors arent reliable becuase they tend to give off false alarms. I dont like having mine go off everytime A train goes by my house, or on days when its very windy. So I thought it would be a good idea to just have my shock sensor give off warning chirps. Then I will install the glass breask sensor to handle the windows. In my mind, there is no such thing as a great car alarm. If someone wants to break into a car, they will do it reguardless of how good the alarm system is.

Man that suxs living next to a train. I use to live next to one and hated it. Your right if someone wants to break in they will the only thing you can do is try to slow them down as much as possible.Thats why my cars got backup siren backup battery glass sensor disconnected door lock switch incase they break the windows and a disconnected trunk switch. I can lock unlock and open the trunk with my remote. Plus I have onstar. Well good luck and hopefully I gave you some ideas for your car. Happy new years
