Defaulting Napco Gemini P800

One of the Napco tech support guys once told me how to do it by shorting certain points. It's been a while and I didn't write it down. The "official" Napco story is it can't be done but like most things in life, the official story has little to do with reality.

Hi all,

How do I go about defaulting the dealer code on the Napco Gemini P800? I think it's locked out. Thanks.

ISTR there was at least one point on the EEPROM involved but I really don't recall for sure. I'm disinclined to offer a guess that might cost you a board.

Solution? New board? Send to Rojas? Thx.

I can wipe it clean.

Jim Rojas

Yeah, I figured you could. Is there any way for me to do it so he doesn't have to wait a week or two? Thanks.

EEPROM opposing corners?

You can use an eprom programmer to wipe the chip.

Then if you place a jumper between terminals 3 & 15, the firmware will then load the default values to the eprom. The problem is getting an eprom reader to wipe the chip in circuit. Most eprom readers will require you to unsolder the eprom to accomplish this.

Much like the story of your life.

Sorry about the delay.. heh... but an 800 can be reset to factory defaults by power> Solution? New board? Send to Rojas? Thx.

Does this really work?

Yes, but it only works if the panel isn't locked out.

So ..... yer sayin that if the panel isn't locked out ..... one has the choice of using the factory default code or shorting the terminals ?

Oooooooow wowweeee! That's really, really cooooool.
