Got up this morning and the alarm panel is humming pretty loud should I disconnect from power? It’s a diy install and secondhand panel been in for couple of weeks been ok until today .
The panel is galaxy 2-12 I’ve just taken lid off panel and removed battery
Put lid back still buzzing
Reconnect batt
Taking off lid can’t hear it but putting back on can (when I put ear on panel )
I’ve also just powered up my old panel which is a galaxy (this one does same when I put ear to panel )
