TROUBLE: NO RESPONSE
SLC 1 ADDR 012 · SMOKE · LOADING DOCK
What you find on arrival
The monitoring company logged 14 'NO RESPONSE — ADDR 012' troubles overnight, each clearing within minutes. Address 12 is a smoke detector at the loading dock. The panel is NORMAL when you arrive, and the facility manager wants to know why this 'random' fault keeps happening.
What do you do?
The fault isn't present right now. How do you hunt an intermittent addressable communication fault?
