Reported cause
Another common cause is the interior monitoring sensor.
Leading evidence: 'interior monitoring sensor' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'interior monitoring sensor' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check any extra wiring' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I've checked the codes for the alarm using the duratec software on 2 consecutive nights but the count of each trigger code hasn't increased dispite it going off between the 2 checks.

The only thing that has changed is that I have had a tracker fitted on Monday.

There is a backup battery in the alarm unit itself - found that when I changed my own battery and managed to somehow trigger the alarm before putting the new battery in - frightened the living daylights out of me!

Suspected cause
As Chris says, a low voltage will trigger the alarm, so I would suspect the tracker.

I've managed to locate the tracker and wiring, so the next step after double locking may be to disconnect the tracker for a couple of days so I can monitor.

It has never gone off before this week and I'm wondering if the tracker unit carries out some check or cycle which may cause a current draw to set the alarm off.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

This car of mine is starting to drive me mad [
]
Can anyone advise if the alarm can be set off due to a voltage drop?
The last 3 nights the alarm has gone off for no apprant reason.
The only thing that has changed is that I have had a tracker fitted on Monday.
It has never gone off before this week and I'm wondering if the tracker unit carries out some check or cycle which may cause a current draw to set the alarm off.
I've checked the codes for the alarm using the duratec software on 2 consecutive nights but the count of each trigger code hasn't increased dispite it going off between the 2 checks.
Please HELP..... for the neighbours sake [

Thanks
Dave
Not likely to be that, then! A tracker does draw current, but your conditioner would compensate given it will only be milliamps. There is a backup battery in the alarm unit itself - found that when I changed my own battery and managed to somehow trigger the alarm before putting the new battery in - frightened the living daylights out of me! Anyway - wonder if that's the issue?
It sounds too coincidental to me that you didn't have problems before the tracker was fitted. As Chris says, a low voltage will trigger the alarm, so I would suspect the tracker.
Another common cause is the interior monitoring sensor. If you double-lock the car it will deactivate the sensor, so you could try that.
Yet another is the tilt sensor on early cars, which is located under the alarm siren. It fills with water, which causes false alarms.
Hi Richard,
Thanks for the information, I hadn't thought about double locking it.
I looked around the siren but ther eis no sign of water - I have been keen to make sure the drains are kept clear.
I also checked to see if this had been disturbed during the tracker install but all looks OK.
I've managed to locate the tracker and wiring, so the next step after double locking may be to disconnect the tracker for a couple of days so I can monitor.
Thanks to you both for the info
Dave.
It did go through my mind that maybe it had been connected to something it shouldnt be.
The only clue I have at the moemnnt is that the 'trigger wire' is brown/red and is in the plenum chamber near to the battery.
I will have a good look this weekend.
Thanks again for all your ideas
Dave
