For the past three years, I have been treated to a regular, but very weak beep, beep - several minutes gap and then a another, but not even constant, it came and went.
I have a linked fire alarm system, I seemed to have traced it to somewhere up stairs, but it alluded any attempt to be sure where it was coming from. Yesterday, I needed something from the loft space, where I have an electronics workshop, accessed by a loft ladder. Just as I dropped the ladder down, there was a loud beep, beep. Found it at last. I installed a smoke monitor up there, not connected to the main system.
