We recently had some painting work done to the outside of the house and the contractor (bless him) silenced the alarm whilst he carried out the painting behind the alarm box. I suspect he removed the alarm box cover, strapped down the tamper device and carried on working before putting everthing back as it was.
Anyway, the alarm system would not work and there were no "day" and "power" lights lit on the numeric control pad. Suspecting a faulty battery in the control box, I ordered the correct Yuasa type and when it arrived, I fitted it. Instantly back to normal -I thought!
But on testing things out, I find that although an alarm situation fires off the outside strobe light and inside warble alarm, the outside siren does not work. However, when I looked in the outside alarm box to check if the wiring was all in place, the tamper alarm sounded straight away.
What might be wrong and can I sort this out (reset it?) myself please?

no need to be sorry mate,we don't use these panels,they are what we call electricians speacials,,try a bell test ,see if sounder operates

So sorry qts. What I meant to say is that I have tested every single fuse in the control box with a multimeter and none of them are blown. Therefore all seems ok - except of course the siren doesn't work!

seems fine sounds like you just looked at it without testing it with a meter ,

No e manno, the F3 fuse seems fine. Anyone else got an idea to sort this one out?

Have you checked it as it protects sounder/strobe.
