Curious - Interior Detectors For Alarm

[TigerFish]

I always though the little clear'ish red knob on the dash was the motion sensor for the alarm. I now know this is the solar sensor for the aircon. This leads me to wonder how the car detect/protects the interior. Where are the interior sensor(s) for the alarm? Anyone know?

i always wondered that on the mk1

maybe in the dome light like the IS?

are you sure they have sensors and are not just activated by the doors etc .

I assume not but you never know. The manual says to press the lock button a second time to arm the alarm without interior detection, for when pets or people are left in the car for a short period of time. I can't imagine they are expecting the pets to open the doors

I've checked round the dome light and nothing there.

I quite often wash the car, forgetting to turn the alarm off, and as soon as I start washing, it goes off, so have to rush indoors for the keys, so where the motion sensors are, I haven't a clue.

Funny you should say that, I did exactly that today. :tsktsk: was it loud, never heard an alarm that loud before, it made my ears ring.

The GS has a Thatcham approved alarm so it has to have interior sensors, either microwave or ultrasonic. On the Series II it is in the centre console however the series I alarm isn't factory fitted, it was installed when the vehicle enters the country, so it's not a well integrated.

Does that mean that on the Mk1, it could be the little "speaker grill" next to the clock?

I believe that's a temperature sensor for the climate control...???
