Presence Sensor 360 (Flush Mount)

• Radar presence detection at 5.8 GHz — senses breathing and slight motion
• 360° coverage, 4 m radius
• Detection area adjustable to 75 %, 50 % or 25 %
• Dry contact output, NO/NC selectable
• Daylight hold-off at 5, 25 or 50 lux
• 12/24 V DC, ceiling flush mount at 3 m

The PIERRE Pro Presence Sensor 360 (Flush Mount) detects that a room is occupied rather than that something moved. Radar at 5.8 GHz picks up slight motion and breathing, so lighting does not switch off on someone reading, working at a desk or sitting in a meeting.

It gives 360° coverage with a 4 m radius, and the detection area can be reduced to 75 %, 50 % or 25 % where the sensor would otherwise see into a corridor or an adjacent desk.

Output is a dry contact, selectable normally-open or normally-closed, so it drives a PIERRE controller input, a lighting relay or a third-party controller. A built-in daylight sensor can hold the output off above 5, 25 or 50 lux, or be disabled.

It runs from 12 or 24 V DC, mounts flush in a ceiling at a recommended 3 m, and is rated IP20 for -25 °C to +50 °C.
