Alarm going off

[R32crew]

Hi guys 

I’ve read in another post about the CT200 Alarm going off at night.

Mine went off 4 times last night & 3 times the night before.

No interference around the car checked cctv cameras.

Has anyone figured out how to solve this issues.

Cheers.

Check you don't have a fly buzzing around in the car. The ultrasonics will pick this up...

One of your windows slightly open ?

Does your remote work ok?

is there an option to disable the motion-sensor, as an experiment?

Heavy rain?

Hi guys 

Thanks for the replies.

Couldnt find any flies in the car the windows where all shut & the remote is working fine too.

I find it a bit strange.

Hi guys

I turned the Theft sensor off & on last night before I parked up for the night.

And guess what it was ok no alarm sound through the night...

Strange 🤗

Excuse my ignorance but what is the Theft Sensor. I only have the remote to set the alarm on mine, unless I've missed something.

Just realised that what you mean by theft sensors are the lnternal movement sensors which are controlled by the switch by the front interior light.

Correct mate 

I thought I’d switch the sensor off & see if the alarm keeps sounding.

I tried it one night off & last night switched it back on the alarm was ok it didn’t go off through the night.

It is lol 😂

I don't think it happens as much with the more modern alarms, but it used to be the case that some alarms

could be triggered by radio transmissions. When I was working and had a transceiver in my van, if I were

transmitting on 70cms (about 440Mhz) it could set off some car alarms.  Discoveries used to be particularly

susceptible.

Mine is ok now. Switched interior sensors off then did an air con freshener incase there was a moth or something in the car. Hasnt happened since.

When my previous Auris did this, i started checking the door switches with a multimeter for good continuity. Found a dodgy one on the driver's door but the main problem was a faulty micro switch on the bonnet release mechanism that I believe was randomly operating the alarm. 

Not sure if the CT has a similar bonnet release or a separate switch some where for the bonnet but worth a check.
