Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Oh, I forgot that they all have to be interconnected and the batteries have to last 10 years. No interconnected system has batteries that will last 10 years so ipso facto you have to have a hardwired system.
What, you mean blazes caused by the plethora of licences electricians that installed dodge Chinese wiring that was in theory recalled? But many owners had no idea about these dodgy cables and some electricians who did their work kept poor paperwork of what parts (supplies cables in this instance) were used in their job… And these professionals didn’t want to spend the effort to chase things down
So wired alarms aren’t the solution that is being pushed… Paint your walls is usually enough to kill the performance where even wired fire alarms wont trigger So the hint is to not throw away those plastic covers that came packaged with the unit and use it to protect the sensor from contamination when painting.Ever seen a painter do such? Over here an electrician signs off on the work and provides the owner with a certificate of compliance. Then in theory once the electrician submitting the paperwork, which he has three days from completion to do, an inspector is supposed to come out and inspect the work within a few weeks. Now I built a house myself and that was finished over four years ago and the inspector never came out, like the regs say he is supposed too. Likely because Town is almost two hours away. Yet in this new house of ours we moved in 7 months ago and are still waiting for the electrical inspector to come out and view the completed works.......What, you mean blazes caused by the plethora of licences electricians that installed dodge Chinese wiring that was in theory recalled?

Concequence, professionals did the work, authorities had no idea where the 10’s maybe 100’s of km of dodgy cables ended up and now we see an increase of house fires… Surprise surprise…
Make the AU/NZ standards free and accessible by anyone who wants to read them. That way anyone who understands what is written within should be more than capable to do their own work safely and to code and simply have their work inspected and signed of by the electrical authority…
Instead, professionals do the work and in one instance didn’t even follow the code around derating cables runnin* tnrough insulated walls…
But nah, protectionism is profitable for the a-graders
We now have the strictest smoke alarm laws in the country. Like I said, battery powered for 10 years isn’t a problem, battery powered for 10 years and interconnected is a problem.
This particular cabling issue can’t be picked up by current requirements. It needs the installer to keep good records of what cable (manufacturer, part numbers, date codes, etc) were used on each job. Then some time down the track if/when it is determined there is a faulty manufactured cable and an associated recall, these professional electrician need to actually perform some work and go back through their records to ensure none of that recalled cable was used by them. They may need to go back over years of work… If such recalled cables were used on any job, then some corrective action needs to be applied to remove and replace the dangerous cables.… How is this funded? May be the corrective action is payed by yje supplier but not all the paper checks which can be substantial work depending how quickly the recall was announced from first importation of these shitty cables..
