Lynx battery replacement in motion detector?

["hfx_chris" <grady.chris@xxxxxxxxx>]

Greetings,

recently my Ademco Lynx woke me up by beeping in the middle of the
night to tell me the batteries are running low in my wireless motion
detector.
I've had this happen a few times in the wireless smoke detector, and
it's quite easy to replace the batteries in that one -- it takes two 9-
volt batteries.
I opened the cover on the motion detector, and the panel downstairs
immediatly started making a rapid beeping sound -- I did a <code> +
off and it silenced it, I assume this is some sort of tamper alarm? So
basically what I want to know is, when I remove the battery (it's a
small little 3-volt I believe, had to find it at Radio Shack), is it
going to mess anything up as far as the motion detector is concerned?
I recall when it was installed, the installer said something about
setting up the motion detector so that our cat wouldn't accidently set
it off, so I'm wondering if these settings are stored in the motion
detector, and will removing the battery reset it?

Thanks for any help,
Chris
