When anything is "Negatively Triggered" this means that usually that, that Circuit, has a resistor of say 10K Ohms, to the Positive Voltage rail. To "Signal" that it is to be "Active: the Circuit is "Pulled Low" by a short circuit to negative/ground. This then gives a negative going signal, that's detected, and the Action performed.


Now usually any Inputs or Outputs have these Pull Up Resistors on the circuit board, and the simple grounding of the wire will "Switch" the Input. So to operate this we would install a switch, with one end on the wire, and the other end wired to the Negative/Ground, when the switch is tripped, it puts a short circuit on that Wire, and in turn, it will operate whatever is operated when that particular switch is tripped.

Most Often an Output is "Tied High" or left alone, as usually the "Logic: of that wire, High or Low, +Voltage or -/0 Voltage, is handled by the electronics internally. You can tell this by measuring the Voltage to earth when the unit is powered up, but not connected. High Out/in puts will have a +12 V voltage on it, or 0V on it. Toggling this line the "other " way activates that wire. If NOT used it is usual to "Tie them high" unless told otherwise.

All/Most Inputs and Outputs aren't needed for actual operation, and can be tested by Tying Inputs & Outputs high or Low, to activate or test a function...

A flame out relay, most likely wouldn't be used, unless you were wishing to monitor for Flame etc. (Sometimes used when running nitro)

Also I find a light bulb on the end of a pair of wires invaluable when testing inputs and outputs, using a small Bulb, you can use it to see an Output or to Trip an input and a visual indication is a lot better when testing

It seem that you do have a good understanding of whats going on, hope i haven't confused you too much and have been of some help..

There could be an issue with the antenna. Is it mounted on the windshield? If so, try moving it to a different location. You didn't mention the year, make, model of your vehicle but, some cars have a filament in the windshield that interferes with RF signals.

I?ll been trying to find the MANUAL of this new car alarm but I couldn?t so if you send it to me I probable will help you.

go to a dealer

It hard to say if your alarm is working properly beside using your transmitter which is working. 3 issue you have that you will have to try to narrow it down. 1st, I would try to contact your network provider base on GSM networks signal coverage checking does your area you live in can received the signal or how strong is the signal in your area. 2nd, does your network provider recognized the sim card or you may have to get new sim card if it defective, they may have to reset it with your network provider. 3rd, is your alarm working properly and is not defective. Have you try to activate the alarm system using it at different locations which has higher signal strength. If its still under the warranty, and you have try all the steps above, the next best thing is to send/take it back and have them bench test the unit or replace it. Being electronics, you have try and follow all steps and directions and it does not work, my only guess is the unit may have become faulty.

sorry man this is very entailed work and if you never did it before it can be very hard most impossible to do. do you have any knowledge of installing a alarm? do you have certain question i could answer for you?

there is just so much to tackle and also what kind of car are you installing it into?

Good I am sorry the other post can not be accessed...send me the info to [email protected]
As far as the other questions:
plus is says it has a wire for immobilizer bypass. do you think it will work without disabling the factory one? It may but it will not be good idea in the long run…it is up to you, my recommendation is to use one not both.
first i need to know if my car has a factory immobilizer and the aftermarket alarm has a wire for immobilizer bypass can i install the alarm without disabling the factory immobilizer? See above.
I will await your email and reply to it to let you know. Please see that grant me your approvals by rating my service and I hope that I can serve you again the future.

I understand how important sound systems are I own one myself. My advice to you is to see if you can get new batteries for the remote. It may have gotten stuck in antihijaking mode when the remote last worked. If this doesn't work try consulting the dealer which you bought your system from.

4.6 Northstar V8. It is located on the rear of engine (driver side) in front. It is in the the water pump housing cover. Remove air box and intake tube and bottom radiator hose. 2 bolts(believe 10mm) on thermostat housing. These systems are a little finicky about air pockets....so fill slowly and let run at idle until operating temp and let cool and check level.....fill as needed and repeat if needed.

A faulty central locking system might be due to several reasons, such as a blown fuse, faulty solenoid, or electrical wiring issues. Also, it's good to remember the fault might not be with the central car locking system but the key fob instead; over time, fobs require battery changes.

Hi, You need to check the output on the charger first, with a meter. Let me know and we will go from there.
