All Cobra alarms have an alarm memory , ie each time the alarm is triggered for any reason, the system remembers the cause of the alarm or intrusion attempt.
When switching off the alarm, which means every time you enter the vehicle, instead of the traditional lights and ringing the buzzer flashers, we have four winks and four rings of buzzer or siren, indicating that there was an intrusion attempt or just a false alarm. Often we leave the glass half open, if not installed a module to increase the glass, there may be a malfunction of any of the sensors or door switches or any other cause that is unknown.
If you want to know what was the cause of the alarm ringing just pay attention to the flashing of the LED inside the car before turning on the ignition and the engine running you can view the information provided by said memory the Cobra alarm that possui.Atenção from the moment you turn the ignition off until this information is the next attempt of theft or false alarm.
Count the LED flashes and identify the reason for the false alarm.
Flashing indicates an attempt to open doors or tailgate.
2 flashes indicate the intervention of the volumetric sensor.
3 flashes indicate the bonnet (very common, bad contacts).
4 flashes indicate an attempt to boot.
5 flashes indicates the entry of the sense of speed or additional sensors.
6 flashes are not used in most alarm Cobra models.
If your alarm rings Cobra often without apparent reason, do not despair, though often the reason these alarms are caused by the switch bonnet (very exposed to moisture and therefore subject to bad contacts and is very easy to clean or replace), note transmitted by the LED flashes the alarm and transmit this information to the technician who will check your system alarme.Essa information is essential to enable the alarm as sometimes the damage does not manifest itself in the workshop.
I hope these have been more useful tips about alarm charges.

Hello, I have an alarm installed in a Cobra Polo 2005. From the pictures it seems to me a 3868 model with the command key.
Lately the alarm has fired for no reason. The code of the LED blinks 1 time / second so that the alarm is the manual opening of door / tailgate.
How can I check the connections and contacts for myself?
There is no installer / shop to recommend in London?
Thanks
Good night
You can check the bonnet switch in a place, take the test off the wire for a few days.

Good morning, how can I do? I do not know which switch and wire hood.
A signal should not be led door / tailgate?
Good morning,
Open the hood and look for a switch (white) and unplug the power cord, is usually in the zone near the headlamps.
It is a simple test and not a diagnosis, may also be the case that the line will be (should at least) linked together through the doors of diodes to separate lines.

good night my car now for a moment's notice kando closing the doors to the presence of light does not wane in the starting of the bag ... there should be alarm ... how can I delete this error? and lock the doors with the command before giving the car vexes 2 4 4 or 5 of flashers vexes ...
Good afternoon,
The problem in that respect has nothing to do with the alarm, probably has one of the switches, port or bag that does not turn off, giving an indication of door / trunk open.
Which vehicle and model?

Good. I have a cobra alarm installed in 2000 in an Alfa Romeo 164. At the moment it happens that, when activated the alarm (with central locking of the doors) it mimics a continuous sound for nearly a minute, but never had any problem.
Yesterday after working the past few minutes it began to trigger the alarm for no apparent reason, and without information (warning light flashing). In other words I had to "turn off" alarm What could it be?? Some contact switches ...
Can you give me a hint, please.
In principle will be the bonnet switch, think is more likely.
You can do a simple test, open the hood, press the switch and turn on the alarm or remove the power switch and turn on the alarm.
If you continue to play will be another switch or sensor (less likely).
I assume that everything else is good: battery, no water entered for any component, etc..

Good, now my congratulations for the excellent work ... He asked for help the following scenario, I had to install the Ford Fiesta 1.4 TDCI (year 2006) my son a Cobra alarm, I think it's a mod. AT-3800 has a sensor on each front pillar, bonnet and a switch attached to the side and use the original command of the car. Almost always after a trip to the rain, to activate the alarm after a few minutes this fire for no apparent reason, I believe from what I read, this might have to do with the switch and more moisture for it to be fixed in the pipeline side where the bonnet is based and where the water circulates. Is it the humidity? What solution is there for this? This situation is sometimes annoying because the solution to turn off the emergency alarm installer is given by loosening the four cover screws and remove the plug, there is no other solution and ignore the hood switch? Grateful for the attention.
It must be checked against the details given by the reason which led the false alarm in order to confirm that fact is due to the bonnet switch, the LED flashes normally 3.
See this image at the correct location of the hood switch
