Hi, Sorry about the capitals, every part of the system works fine and has worked fine since it was fitted have done the alarm tests the only thing that does not work is the strobe test as per the manual. Only noticed the fault when the light in the bell box was not on witch it it has been since it was fitted.
assuming it has worked (sorry i dont know if it has or has not) and since everthing else still works, and you are following the test procedure, its a safe bet the strobe has exceeded its life expectancy
short of you going up there and connecting 12v directly to it, there is not much else you can do
