1550.0. "Cause for alarm ?!" by HAMPS::TAYLOR_P () Tue Sep 17 1991 12:46

    I have just purchased an 18 month old Cavalier CDi which comes with an
    alarm system factory fitted. All was well for 4 or 5 days until I
    deciced I ought to know about all its functions !  It has a push button
    beside the ultra sonic transducers in the car and this button is
    supposed to mute the ultrasonic detection (if for instance you wanted
    to leave a pet in the car). Well ever since I pressed it inquisitively
    the transducers have produced a regular ticking and create a pressure
    sensation in the ears - presumably they are emitting ultrasound. This
    is continuous and setting/cancelling the alarm has no effect on it
    although the alarm status light functions normally. Disconnecting the
    battery does stop the effect, but reconnecting it restores the problem.
    My nearest Vauxhall dealer is A.C. Barnes and is so far baffled. Can
    anyone advise ?
    
    Thanks,
    
           Phil.

1550.1	very alarming !	UBOHUB::CROME_A		`Tue Oct 01 1991 17:41`	1
	Have you pressed the button a few more times .....
1550.2	Tick in the box ?	HAMPS::TAYLOR_P		`Fri Oct 04 1991 14:17`	7
	Yes, I've tried pressing the button several more times. I've also listened very carefully to several other Cavaliers with alarms to discover about 50% have a continuous clicking, though usually quieter than mine. My conclusion is that it is not a malfunction but a feature and that I probably have more accute hearing, especially for problem noises after I have just bought a car !!!

	Do the ultrasonics work? Mark PS Easily tested by getting my wife to lock the car! :^)

	Now, how much would it take to get her to forget to let you out again ? Ian ;-)
1550.5		NEWOA::SAXBY	Aye. When I were a lad....	`Fri Oct 04 1991 17:39`	13
	Sorry Ian, it doesn't work that way (although the answer is �25 :^)) Somehow, despite her protestations that she has locked or unlocked the car correctly, she has an unhappy knack of setting off the car's alarm. Even when all the doors and windows are locked and no-one is around! Of course, needless to say, it never happens the 99% of the time that I drive the car! Mark
1550.6	Saxby, a chauvanist, never !	CHEST::RAWSON	Things that make you go Hmmm	`Fri Oct 04 1991 17:51`	5
	Mark, naughty, naughty ! I bet you wouldn't say things like that if she could read this conference ! Alex :^)
1550.7		NEWOA::SAXBY	Aye. When I were a lad....	`Fri Oct 04 1991 18:01`	4
	She wouldn't like, but she couldn't disagree with it. Mark
1550.8	Click, Click	HAMPS::TAYLOR_P		`Fri Oct 11 1991 18:43`	8
	Now that I'm out again, I can confirm that the ultrasonics do work, when they are supposed to (i.e. locking the car without pressing the "disarm ultrasonics" button) and don't work when they are supposed not to (i.e. pressing the disarm ultrasonics button before locking the car). What I don't understand is why they transmit continuously. The clicking is there and sounds just the same whether the alarm is on or not. Phil.
1550.9	Not the cause, but the effect	TIMMII::RDAVIES	An expert Amateur	`Mon Oct 14 1991 15:07`	4
	Obviously doesn't turn off the ultasonic detector, only the triggering by detection. Richard
