huatai ht 800d false alarms

Another EBAY disaster. I have a 2006 dodge magnum HEMI and this alarm really sucks. Its got features but not nice like others. Any way I keep getting false alarms when I lock the doors. First off this alarm will not chirp your remote if a door is left open the alarm will just go off and embarace you as your walking away from your car. I will lock my doors then 15 seconds later the alarm will go off saying I left a door open. Then I will unlock then lock again with out even touching the car and now it works fine. Some times it will not do that, and I can keep walking to my destination. But I have to sit by my car for 15 seconds so I can cut off the siren fast before every one looks at me.

I need advice as to what to look for. Why is the alarm saying my door is open, all I have to do is rearm and its fine.

Sounds like you have some back feeding to your door trigger. Get something that i at least heard of haha. Spend some money and get your self something worth the value on what your car is worth. Some times i just don't understand why people but junk into their nice expensive rides? But hey you live and learn. Did you at least get it perfessionally installed? Get your but into a compustar pro for a car like that doodie. P2W900FM-AS. WORD

"dont ground out!"

thats the only real problem I have with it, evry thing else is fine and the range is better than my last DEI hornet.

any body else can help me

its to bad know one was able to help me. I found out all I needed to do was diode Isolate on my door trigger. I know this is known and am surprised no one was able to help me. I hope this helps some one else.

Vehicles with Body Control Modules that shut down causing false triggers on the door and rear hatch/trunk inputs. Generally, when body control modules shut down to save power there is a change of state on the door trigger wires that aftermarket alarms see as a false trigger. Isolating the door switch wires using either diagram eliminates the false trigger. All diodes are rated at 1 Amp.

You need to diode isolate the door triggers. You can purchase the 1 amp diodes needed at Radio Shack.

Update the bypass I used must have been defective some how. The false trigger came back. What I did is ran the alarm directly to the door triggers with diodes. I used the bypass for every thing else except the door triggers. Now every thing works great.
