NAPCO RP1-CAE2 KEYPAD PROBLEMS...

system, on power up the keypad compatibility number change in the keypad. Only one keypad as well per site, so not as if it was a single site issue.

I use Napco panels exclusively. Long long time ago, I had some issues with the "compatibility" feature in a commercial job. Now that I do mostly residential, I don't use that feature. I'd suggest that if you don't have to use it for a high security situation, there's no reason to do so. Could never figure out what real purpose it had anyway.

It's an anti-takeover measure, Paradox has it as well

I KNOW what it's SUPPOSED to be but what difference does it make if someone changes a keypad on a job, or not? No one could take over the job if they can't get into the panel anyway ..... is what I was alluding to. I guess it's to stop someone from stealing your keypad? I haven't heard of a rash of keypad stealing, in many moons. On the other hand, Jim DOES seem to have a lot of them in his garage.

What an idiot! The idea is to make it more expensive to do a takeover. Instead of replacing the whole panel, a competing alarm company can simply swap the chip. However, with the keypad compatability number altered they would have to replace the keypads as well -- at significantly higher cost. The thinking (I know, that's a foreign concept to you) is that the new alarm company will try to foist the expense onto the customer but the customer will balk, opting to stay with the original alarm sealer.
