White light filters minimise the risk of a FA, sometimes installations don't lend themselves to installing the best way. Especially in retro situations. Often for example on a landing the best corner is over the stairs. I wouldn't install there due to future access issues so then your usually left with facing a window. They have some tolerance but you minimise the risks just like anything else. I'm not saying a good quality quad couldn't be fine. When you have the option available you install them in the best possible corners. Which the simple version is always pointing away from sources of light and heat (the sun) and perpendicular to the movement of any possible intruder. All manufacturers instructions say this and if you ignore it and have a false alarm it's your own fault. Had a job Tuesday were some tool had pointed a Honeywell PIR at a patio door in an open plan extension, it had false alarmed every day all the week prior. The system is 5 months old fitted by some clueless spark (scribbled colours/terminals on manuals...), seems to be a mess. It's only just started these FA's but you can see from the time in the log it's happening during the day when it's competing with the sun on the back patio. Re-siting has solved it, maybe a quad could but I don't see that as the correct solution... it's just a workaround, the bad positioning was the issue and would still be there IMO. Anyway, tis true G3 is pointless at a DIY level, it's much greater chance of headaches than ever genuinely detecting what it's there for. It could also affect everything I am saying about positioning. For example, they are designed for open commercial spaces if your fitting in corners with possibly of curtains or tall furniture you may have to consider a less ideal corner. Master bed you have cupboard doors opening onto the ideal corners, this will likely cause a mask. Or if not and maybe you left the doors open you have no detection. There is more to design than the ideal manufacturers instructions or looking at top view building plans and more unnecessary issues to jungle throwing G3 components in the mix.

Thanks for the welcome messages guys... I've managed to track down a suitable course. Booked in next month ? Will update this thread with my experience and looking forward to getting my first install ?
