Designed for any indoor space in which you need a multi-sensor, Recessor’s installation starts with simply selecting where you want it. Wall. Ceiling. Cavity space. Once selected, make a 75mm / 3″ aperture within the chosen surface and then secure your sensor within Recessor – it’s compatible with MultiSensor 6, MultiSensor 7, and TriSensor – simply by fastening it using Recessor’s connection mechanism. Then you’re ready for the final step; insert the complete unit into the aperture and Recessor’s spring-loaded grips will hold it in place without the need of screws or glue.
