No, you entered into program mode 4114800 + 21 (I think, been awhile since I've programmed one of those) and add it as a "sensor" which requires you to press and hold a button which the serial number and/or MAC address of the key fob is written into be allowed to communicate to the controller. Than reboot *99 and you're good from than on.

Check your manual there is a particular zone range for these to be added too.

You don't say what kind of control panel you're trying to add this to, but I would guess a Vista 20 based on the symptoms. You cannot use a 4208U for this panel...what you need is a 4219, but even that may not work because Honeywell has changed the components without changing the part numbers, making the new expanders incompatible with older controls. You may need to upgrade to a Vista 20P.

I'm sure you found out by now, based on the age of this question, but just in case, that the 998PI is hardwired and does not have a battery of its own.
