PSA: That old grocery store alarm would trip if a fly landed on it

I replaced a system at a Food Lion off Route 17 in Fredericksburg last month. The old DSC panel from 1999 was so sensitive that a coolant pipe shifting in the back room would set off the glass break detector. Night crew told me they stopped resetting it after the third week because it would false every other night around 2 AM. Anybody else run into ancient panels that just need to be put out of their misery?

Is it possible those old panels actually have failing capacitors that mess with the voltage just enough to trigger false alarms? I cracked open a 1998 Ademco once and found three bulging caps on the board leaking brown gunk, probably been doing it for years. The sensitivity drift might not be "old age" but actual component rot that makes the thing scream at a moth farting three blocks away.

Man that capacitor gunk sounds nasty, totally feel your pain on that one.

Yeah that false alarm cycle thing is basically the same as my old car that started beeping at random when the battery was dying, it's like these systems just start screaming for attention before they finally give out. It's the same pattern everywhere I look, from my phone freezing up before it crashes to my neighbor's garage door opener acting possessed for a month before it died for good. Old tech doesn't just quit, it throws a tantrum first and makes you question your sanity.
