This detector was part of my Yale SR alarm system that worked very well. Unfortunately a damaged siren has meant that a new system was required and this sensor has to go. No box, batteries (3*AAA batteries req.) or instructions included as these were thrown away at installation/removal although I am more than happy to help you with installing it via messaging. The Yale Easy Fit PIR Motion Sensor SR or EF is a white, battery-operated motion detector designed for indoor use. This unit features keypad control, Wi-Fi connectivity, and is pet-friendly. Please note : This sensor is for YALE SR or EF systems.
