Webasto Pre Heater & Alarm sensors.

<< < (3/4) > >>

Gary:
your welcome Andy

glad to be of some help mate  :wink:

I will follow this thread with interest as a webasto unit is on my wish list and I to have an alarm system on my defender.  :roll:  Mines not a LR alarm so I can possibly see some investigation will be needed when I eventually go down the same route.

Regards, gary

Andy.:
The pdf file that Webasto sent me is for a TD5 Defender, if you want I can send it too you  :?:

Just PM me your email address and I'll send it.

Andy.:
Well tried the heater without the duck and it still sets off the alarm.

I could turn the blower setting down to one but I think this will be less effective on a cold frosty morning. Or install a relay as Webasto have said, but don't really want to mess around with the alarm wires.

One more option to try is that whenever I want to use the heater I lock the motor with the key rather than the remote. This way I arm the vehicle with perimetric protection and this turns off the ultrasonic unit. When arming with the handset you activate the volumetric protection with the sensors armed.

In fact I do have a LRSS alarm system to fit, had it for over a year now  :shock:

Andy.:
Just another thought too, by using the key and arming the vehicle via the perimetric protection am I not doing exactly what a relay would do  :?:

I would only use the key for when I wanted to use the pre heater, all other times I would revert back to the remote and again arming the sensors.

Hi Andy

that's a bummer it wasn't just a case of removing the hanging item from your mirror  :(

Are you saying that when you manually lock your vehicle with a key that it activates the central locking AND "part-sets" the alarm system?

Is your alarm Cat 1, does it have an engine imobiliser built in with it?

If so, does the imobiliser activate automatically after a pre-set time or would this be actiavted by either the use of the Remote Alarm Fob or the use of the key to lock the car?

I'm just curious to see how your Alarm system operates or how it has been set up.

I'm trying to determine for you if your vehicle will be less secure if you choose to lock it manually with a key so you can operate the Pre-heater  :roll:

Also, if you choose to lock your vehicle with the key only the night before so your Pre-heater can cut-in in the morning without a false actvation of the alarm......I presume you could still you your Remote fob to unlock the vehicle in the event that the weather was that cold that the door lock might be frozen  :shock:

having said that.............

It would be nice to presume that the Pre-heat system would allow a defrosting of the engine, cab area and the door lock mechansim  :wink:
