Alarm sounding when windy
Looking to get this sorted as it's totally doing my head in, any time it's windy my alarm goes off it's nut and it's been the same through different batteries that have been fitted, I have to try and park between 2 cars anytime it's windy to stop it happening........ I have no idea where to start with a problem like this but know I need to do something, any advice appreciated

Cant you dis arm the interior sensors for a few nights, see if its that?

Warning: Impreza and Forester models from 2003 model year and Legacy models from 2004 model year are equiped with double-locking doors. People should not be left inside these vehicle s with the alarm armed under any circumstances. When armed, the vehicles doors double-locked automatically and cannot be opened internally! If armed in error, with an occupant in the vehicle, the system should be disarmed and a door must be opened and shut to prevent auto-rearming and locking occuring. Arming the security system without ultrasonic interior protection will be necessary, yet still provides limited protection, if you wish to leave animals inside the secured vehicle or the windows/sunroof open whilst the vehicle is left unattended. Sensible safety precautions should be exercised if considering these actions! To do this: Turn the vehicle s ignition on,give the radio transmitter button a quick press. The dashboard mounted LED will flash once. Turn off the vehicle s ignition immediately. Vacate the vehicle closing all doors, boot and bonnet. Give the radio transmitter button a quick press, whilst standing near the vehicle. The security system will acknowledge arming with 8 flashes of the vehicle s hazard warning lights, instead of the normal 4. The doors will double-lock as normal. Ultrasonic interior protection will be restored the next time the security system is armed in the normal way. * Also possible using the multifunction keypad. See page 11 for details. Excluding Ultrasonic Interior Protection (Option 2 on the keypad) Arming the security system without ultrasonic interior protection will be necessary if you wish to leave people or animals inside the secured vehicle (sensible safety precautions should be exercised if considering this action!). This facility may also be used to provide limited protection of the vehicle if left unattended with the windows and/or sunroof open. To do this turn on the vehicle s ignition, give the radio transmitter button a quick press, type 2 on the keypad and immediately turn off the ignition. Vacate the vehicle, closing all doors, boot and bonnet. Now arm the security system in the normal way. The security system will acknowledge arming with 8 flashes of the vehicle s hazard warning lights, instead of the normal 4. Ultrasonic protection will be restored next time you arm the security system in the normal way. |
Have you tried closing the air vents ? If you have anything dangling down from anywhere in the car then air being forced through the vents may move the object(s) thus causing the alarm to activate. Even a small amount of movement could be picked up by the internal sensors. Worth a look. Andrew. |
Will give both a try, just seems very sensitive to wind round about the car

As mentioned, some (most?) alarms have some kind of manual sensitivity adjustment - usually located on the actual hardware (normally mounted in the engine bay).
So you might be able to reinstate the interior sensing facility, if you first turn the sensitivity down. Trial and error adjustments maybe be required. |

So you might be able to reinstate the interior sensing facility, if you first turn the sensitivity down. Trial and error adjustments maybe be required. Note regarding ultrasonic operation and adjustment: The ultrasonic system in the Sigma M30 employs a sophisticated micro processor controlled method of detection. Unlike conventional ultrasonic detectors this method ensures that an actual entry has occurred rather than just air movement, air pressure fluctuation, seat belt movement etc. The detection system also employs a movement/time method where a certain amount of movement in a given time is required to cause a trigger. This method of detection offers a high level of protection against false alarms commonly associated with other systems employing inferior methods of detection In order to test the operation of the ultrasonics it is important to understand how they works when the system is initially armed: • For the first 16 seconds (settle time) the system allows the air movement inside the vehicle to stabilise. (During this period the LED flashes dimly) • During the next 16 seconds (threshold settle time) the microprocessor monitors the interior of the vehicle - reducing the sensitivity (from the maximum sensitivity programmed by the installer, if necessary to suit the interior and climate. (During this period the LED flashes brightly - latching on for a second only if movement is detected and the sensitivity has been reduced) • After the first 32 seconds the system is now fully armed and the ultrasonic sensitivity is set to the programmed maximum or the reduced level if some movement was detected during the “threshold settle time”.(LED now flashing dimly) Because of the way the ultrasonics operate, if there is a disturbance within the “threshold settle time” the ultrasonics will re-adjust to compensate for this disturbance, if the movement is excessive the ultrasonics may turn themselves off. This re-adjustment can be detected by the dash mounted LED changing from flashing, to a static state for a second. This may happen if the ultrasonics are tested in windy conditions with a window open. If this is the case then the folowing test method can be performed: Close all doors, bonnet and windows sitting yourself in the rear of the vehicle. Arm the alarm system keeping very still, and observe the dash LED during the “settle time” and then the “theshold settle time”. The LED must remain flashing and should not latch on. After these 2 periods the LED will then flash dimmly again, moving your head forward now should trigger the alarm. |
