Ron,
Here is the alarm I have.
http://www.clifford.com/Products/Pro...?ProductID=716 I have the older style remotes, but the same system. The one I have has impact sensor, glass break sensor (microphone), door open sensor, trunk pop, dual starter interrupt (even if you disconnect the alarm, you have to know were the 2nd interrupt is or the car will not start), and it is programmed to auto arm. I also got the data port installed, so the shop can hook up a laptop and change my programming without having to tear into the car. Even if I disarm it and walk away it will re-arm after a couple of minutes. When I get out of the car and close the door, it will chirp after 15 seconds and lock and arm after 30 seconds. I can disable auto arm by turning the ignition on and off quickly. The next time I start the car, auto arm will be re-enabled. This is helpful for gas stations. Valet mode is set by pressing a 2 buttons sequence on the remote, or by the valet switch. The valet switch is not a toggle, it is 2 buttons that you must "dial" the code in. Button one is the number, and 2 is enter. You program your own code. For code 34, you would press button 1 3 times, button 2 one time, button 1 4 times, button 2 1 time. This prevents anyone from not knowing the code to disarm it and you never have to give the valet/service center your remote. My version also allows for 2 accessories to be added
