Plafondgemonteerde passieve infrarood bewegingsmelder GIRA 210602 — bedrade PIR, 2 m bereik, 360°-detectie, wit, AC

The GIRA 210602 is a ceiling-mounted passive infrared presence and motion detector with integrated KNX bus coupler and wired AC power. Designed for indoor use, it provides 360° coverage and a detection range up to 2 m. The device combines three crossed-path PIR sensors and an integrated brightness sensor to detect presence, perform ceiling-observer motion detection, or send alarm telegrams; sensitivity and operating behavior are configurable for integration into lighting and security systems.

Advantages

The detector is a flush-mounted unit with a visible programming LED/button that remains operable after installation if the ornamental ring is removed. Three PIR sensors provide separate long-range evaluation with overlapping detection zones, and a manual sensitivity adjuster is available on the device (can be deactivated in software). Motion indication can be permanent or limited to a walking test, and manual operation is possible via IR remote control. Up to seven function blocks (5+2) are configurable to support modes such as ceiling observer, presence detector, light control, and brightness limit monitoring, plus options for adaptive delay, teach-in, and external object control.

Key specifications

How to use

Install the GIRA 210602 as a flush-mounted ceiling unit and connect the KNX bus and AC supply according to the installation instructions and applicable electrical standards. Remove the ornamental ring if you need access to the programming LED/button after installation. Configure required function blocks and operating mode using KNX tools or the device interface: choose ceiling observer, presence detector, or alarm device modes, and set sensitivity, detection ranges, delay times, and twilight thresholds as needed. Use teach-in or external communication objects to set brightness limits, setpoints, or to change function blocks (for example day/night or weekday/weekend modes).

Recommendations

For reliable detection, mount the detector centrally on the ceiling of the monitored area and verify coverage with the walking test. If manual sensitivity adjustment is not required on-site, disable the device adjuster via software to prevent accidental changes. Use teach-in and external communication objects to integrate brightness limits and setpoints into your KNX automation for consistent light control behavior.
