Morning all! Hoping someone can give me some help or advice! I bought my house in feb of this year and immediately began doing the usual fixing and replacing. One thing I haven’t yet properly sorted is the Racal Guardall RLC1 light control unit that’s in my kitchen on the wall. it was faulty when I moved in, in that if the rocker was in the centre nothing worked, but if I had the rocker on auto, or on, the light outside would stay permanently on. I can also see the light has a separate sensor further up the wall. Not sure if that’s what is broken so that it was always on when on auto or if it was the panel. either way, I needed a security light up and quickly, so I removed the old light, put up a light with an integrated sensor and flicked the rocker to always on. This was I figured it would power the light and it’s sensor and job would be a good one! All worked as should up until this morning when my boiler wasn’t working. Breaker switch had gone, but this is labelled in the box as “light control unit”. pit the breaker back to on, boiler now working but the light isn’t. i suspect it’s taken it’s last breathe. now because I’ve got the light with PIR outside already which literally has a mains going in to it from the wall, can I replace the RLC1 unit with just a normal light switch for example? Im really not up on where the power is pulled from for the light itself and how the box and sensor all triggers it. Assume there’s a relay somewhere so the box has power, sends that to the sensor, sensor says yep we see something then it flicks a relay in the box and that then send s power to the light? i want to avoid having to run any new cable through walls as it’s really not the weather right now for that! Blizzards galore up here in West Yorkshire! muchly! Joel
