Wired a custom home 6 mos ago, owner says that smoke alarms will sound off for a second then stop, happens maybe once a week and will only be one alarm that warps and each time it will be a different room that goes off for instance last night it was his room and the week before his sons room? he sent me a certified letter stating his complaint but I do not know how to approach this?
