I have a MY97 with the standard imobiliser and a Sigma Thatcham cat 1 alarm. If I fit a turbo timer, will it overide the imobiliser until it switches of at the end of the cool down period?

Also, will the car alarm set as normal, if so won't the current sensing trigger the alarm at the end of the 30 second settling period?

Hello m8
If depends if you wire the timer before or after the alarm if its after it will not affect the alarm at all.............

 

And sigma do not use current sencing!!!!!!!!!!!!

 

That's interesting, so how come operating a door switch, like the drivers one sets off the alarm or just turning on the cabin light does? I know the ultrasonics aren't set that sensitive to catch the switch/hand movement.

 

Hello mate
The alarm is wired to the door pin switches
You can,nt use voltage drop on modern cat 1 alarms thatchams will not allow it....

 

OK thanks for that. (I am sure turning the light on by hand would cause it to go off, will have to try it later).

 

If your sonics do,nt pick up a hand moving in the car take it to your nearest installer to get them set up proply
They will nead to have a sigma programer!!

 

They work fine thanks, my son sleeping in the back set them off at the garage the other day! Must have been his snoring

 

My understanding is that if you fit a turbo timer it will void the Thatcham approval of your alarm!
