My dti dss-52 will no longer sound the test alarm when attempted?

If you don't tell me what's going on then I can't help you.

I have the book here and that's something you will struggle to find.

I'l tell you something I've noticed in the manual unlike our UK panels,there's no fuse protection for the battery/charging circuit so if the battery is hooked up wrong or there's a short,then you can kiss the panel goodbye.

So if you have replaced the battery and reversed the polarity.....BOOM BABY!.

Is the AC "power" light lit and have you replaced the 1.5Ah battery?.

Check the AC transformer if the light is not lit.
