What solution might you try for this situation?
In a remote mountain lodge, I replaced the main board of a lightning fried Siemens Pyrotronics CP-30 FACP. The caretaker reports that a few minutes after the boiler goes on, the alarm sometimes goes into trouble. There's a fan operated water to air exchanger on the same sub-panel. Likely the motor startup is enough to disturb the linear power supply on the old CP-30. The location is a 4 hour drive away, and it does not happen all the time, so diagnosis is not so easy.
Note: To address the lightning surges, I added a panel mounted TVSS surge protector (basically a knockout mounted version of those in Whole House Surge Protector Guide ). That protects the entire sub-panel, but of course that won't address motor noise.
