In this video I’m fitting a Texecom 360 ceiling PIR step-by-step, exactly how I’d do it on a proper UK install. I start by popping the cover off (little grub screws on either side) and walking you through what you actually get inside: the terminals, the sensor, the DIP switches, and the resistor block. Texecom are moving away from paper instructions now (it’s a barcode/scan job), but the key takeaway is the resistor block setup—on Texecom I’m using the option that gives you 2K2, 4K7, 2K2 for double end-of-line. From there I show the cable prep with standard 8-core alarm cable and explain why I use it: flexibility for extra devices, longer runs/volt drop, or future changes. For this sensor I’m only keeping four cores (red, black, blue, white) and trimming the rest because I’ve got plenty of slack. I drill the entry hole, strip about 12mm, twist the cores, and terminate before it goes up on the ceiling—work smart, not harder. Finally, I fix the base properly (yes, it’s a security device, so I’m not making anyone’s life easy), making sure the rear tamper is doing its job, then re-fit the cover. I also explain why I like 360 ceiling sensors: they give true room coverage and avoid the headache of relying on perfect corner first-fix cable positions.
