Hello all, I’m pretty uninitiated in electrics and wonder if this garden installation is possible and what I might need to achieve it. I have a garden room which I am finishing and having wiring put in. I will have 240v external sockets and bare cable that can be wired directly to a transformer if needed. I wish to place two EZVIZ EzGuard security cameras on the Garden Room. They each come with a DVE Switching Adapter (input 240v 0.5A, output +12V 1A, Efficiency Level 'V'). I also wish to run some garden lights starting from the garden room running along all along the garden wall. The first 10 - 15m of the wall will be draped in some LED fairy lights, and the next 10 - 15m further along the wall will continue with 6 bollard/post lights (about 50cm high ones). From a cursory glance it looks like 2 x 10m LED light strings would be 2W each (4W), and 6 x LED bollard lights about 2W each (12W). I would like all three zones switched independently. My first question is, can these all be run off one transformer, and if so, which one is suitable? If not should I install 3 transformers? One for both cameras, one for the fairy lights and one for the bollard lights? 12 or 24V for the lights? I know there are generic transformers and also generic lights out there, and there are also bespoke ones from the likes of Techmar, in-lite and Konstsmide. Is it easy enough to work with the off-the-shelf stuff or much better to go with these all-in-one premium brands? Secondly, is it possible to switch the two sets of lights independently and does this mean they must be powered by separate transformers? Can they be controlled wirelessly with a Kinetic Self-powered Wireless Remote Control and receiver like the Curv CV05 on the output of the transformer? The details are: Wireless Receiver: CV05 Power Supply Input: 220V - 230V AC, 50/60HZ Output Type / Channel Numbers: “On” or “Off” output of power supply / 1 channel Max Load 5A Load Of Filament Lamp: 500W Load Of Fluorescent Lamp: 200W Load of LED: 200W Static Power Consumption: <1W

Not quite sure to address this, so I will just ask this question about connections such as hard wired fire alarms and PIV fans (typical load 10W) etc Now, there is no issue with us doing those on our own home, provided we do it right. Or having an electrician do the same. I am interested as a landlord. The big issues (obviously) are the linked ones of tenant safety and potential liability, with cost getting a look in once appropriate standards are met. My practice in a full rewiring would be to get the electrician to do hardwired alarms then it is certified with the rest under the 5 year inspection. In a non-wiring small refurb or existing house I currently use 5 or 10 year sealed battery alarms to avoid the ‘tenant not replacing battery’ safety issue. I need to check current regulations before I do the next one. My questions ... probably for tradesmen mainly, are: 1 - How are low power connections regulated? Is it Ok for a non Competent Person to connect up a PIV fan to say the lighting power wires? is it OK if the connection is to a Competent Person pre-installed Connection unit in the loft? The latter would save a second visit by the Electrician. 2 - What about fire alarms? 3 - What about 12v fire alarms? IIRC 12v is not regulated. 4 - Is there a significantly different fire hazard from using 12v vs 240v wiring for eg fire alarms? 5 - Does this mean that running a stepped down to12v circuit into the loft space is a good idea? 6 - Are there many pros or cons to using 12v lighting? Thanks for any replies Ferdinand
