Product information "HIR28"

HIR28 is a PIR stand-alone motion sensor designed for independent lighting control with relay ON/OFF output. It is suitable for retrofit and small-scale applications where simple, reliable switching control is required. The sensor provides occupancy-based switching and optional absence detection, while an integrated photocell prevents unnecessary light activation when sufficient natural daylight is available. Configuration and commissioning are handled via a handheld remote control, enabling quick setup and one-key commissioning for multiple devices.
