I believe I've seen postings similar to this, but I don't recall the response. The scenario: A system that includes various components, all listed/approved/evaluated according to 'product family specific' standards. While the system can/normally does operate independently, a user can monitor/communicate with this system using a standard off-the-shelf personal computer via LAN/WAN. OR the PC can be co-located with the system and connected directly via RS232. Further, with an off-the-shelf consumer add-on card, the PC can also send a signal to an alarm panel. The question is, does the PC fall under the product family standard of the system - in either case. PS: the user can buy a PC themselves if they like and merely connect it and add the software. Does that change the requirements? John A. Juhasz
