While out the alarm strobe activated then siren (for about an hour) then just strobe. Teenager returned and unset the alarm (no useful info) - zones all reset. However, strobe still flashing. Read Operating instructions & Engineering information cover to cover and can find no reference to this type of fault.
Have tried testing and reseting -all appears to work but strobe still doesn't reset. Anyone had this problem? and or knows how to rectify it? Help would be appreciated.

Yes come across this and many other problems with the Accenta. It is normally the battery that is dead that causes this. Dont ask me why, how the battery is connected to the strobe is anybody's guess, Change the battery, and your probably find you resolve the problem.
