It has the fuses yes but they didn't blow or protect the PCB enough as the power spike blew it.

Zone 6 has a wire loop link in the contacts only. All others used.

We have a lot of power cuts in our rural village and our solar inverter shows our mains voltages all over the place. Our alarm panel was killed by our last power cut which flickered on and off about 3 times before going off. I have a new panel so I wondered if I can add some sort of breaker...

In the command list is the option zones omitted in part set? And another saying zones not used but it's really not clear what to set in the instructions. I've a hand written key suggesting what the zones were from 1 - 4 but I think an extra pir was added? Should I use the "zones not used" and...

In a power cut my 9448 alarm must have been damaged as when power was restored no green light came on and the board was dead. I've bought another main unit and swapped the PCB over and it's now up and working partly. I reset to the default settings and wired it up exactly as before. I can't work...

does that make the green power light come back on? All seems dead?

We have 3 key pads and all are lit with beeping buttons but none responsive i.e. no red lights and the engineer or user codes don't work.

After disconnection of the transformer it now seems to be working ok but still no green light. All 3 fuses on the board are ok. Battery ok and leads getting 12v supply ok to battery. So has my circuit board failed I wonder?

We often have power cuts and I often have to reset our alarm as the back up batteries run out when we get all day cuts as per the last one. Now the main box with battery seems dead as no green power light. I've tested for mains 240v in which is live but if I take the transformer plug off the...
