    Well neither the BC-30 nor BC-31 appears on the list, so your kind of low budget will have to include a BC-35 if you're upgrading to a CP-35. There is also a battery retention system made for the System 3. I'm hoping that your surge suppressor costs are already covered

    Regarding the newer Siemens SXL-EX panel, why would this be considered an installation? Could this not be handled as an emergency panel replacement? You have already indicated that the panel goes crazy during bad weather. How much more life do you figure is left on the several remaining 37 year old daughter cards anyway?

    In battle, in forest, at the precipice in the mountains,
    On the dark great sea, in the midst of javelins and arrows,
    In sleep, in confusion, in the depths of shame,
    The good deeds a man has done before defend him.

    In followup:
    Thanks for everyone's help. In this end the fire panel was repaired, with a surge protector added to the feeding distribution panel.

    In California unlike other states, repair does not trigger a code upgrade requirement (reference: http://osfm.fire.ca.gov/informationb...L_20080910.pdf )

    The 37 year old equipment issue is interesting, but as far as I could gather the equipment is not actually nearing effective end of life. There are still active repair companies such as http://hvfire.com/ , widely available spare parts, and the System 3 is regarded as not just bulletproof but standard equipment on Nuclear Submarines. All the zones are supervised and inspected monthly, so perhaps we can have this conversation again in a few more decades after the plastic parts start to degrade.
