Hi, so I've inherited the above, obsolete I believe, alarm system and everything seems to be working OK aside from one thing. Every night on the stroke of 23:00 it will emit a series of bleeps from the internal speaker that lasts around a minute. These bleeps commence as two bleeps, onto three and finally four before falling silent until the next night.
It baffles me as I cannot see any reference to this phenomenon, and the previous owners don't either, in any manual.
Anyone got any clues?
