BUILDING AUTOMATIONS Motion detector: communication objects Motion detector 20850, 19850, 16850, 14850 Passive infrared motion detector, KNX standard, grey 2 modules. 20850 19850 16850 14850 Functionality This device detects motion within the sensor's range of action. When the movement has been validated by an internal filter, a "presence message" is sent over the KNX bus and the green LED lights up. This is done according to the set brightness threshold. Note that the green LED does not light up every time a movement is detected, but only when a "presence message" is sent. The device is capable of activating a movement event from an external source or from any KNX device. A twilight sensor is also present which causes the lights to be turned on or off according to daylight brightness levels. It is possible to set two types of threshold (upper and lower) and to perform various operations according to the current level. These actions allow individual or cyclical On/Off messages to be sent. It is also possible to postpone message sending to validate the effective level of the light sensor. For MASTERSLAVE operation with multiple motion detectors, refer to the explanation of KNX object no. 2 "External trigger". Behaviour after bus on/off Bus off: data are not saved. Bus on: motion detection is enabled after 30 seconds, the time necessary for the IR sensor to stabilise. Behaviour after reset As for bus on. Communication objects List of existing communication objects Communication objects KNX objects: motion detector in detail. Motion detector communication objects Number ETS name 0 Motion detector 1 Motion detector Function Movement switch Forced Disabled Description Length (if the "Motion Detector" parameter is enabled) - a bit that goes to "1" if a movement is detected 1 bit (if the "Motion Detector" parameter is enabled) to deactivate the motion detector via the bus so that the device does NOT send multiple messages 1 bit on detecting a moving body Flag 1 C RWT U X X X X 2 Motion detector External trigger (if the "Motion Detector" parameter is enabled) if there are multiple PIRs set as "Motion detector" controlling the same light, choose one as MAS- TER and associate its "Command on movement" object with the "Trigger" objects of the other SLAVE PIRs in the same group as the relay to be con- trolled (so for the SLAVE PIRs the "Command on movement" object will be unused). This way each SLAVE PIR will be able to reset the time count 1 bit of the MASTER PIR, which via the "Command on movement" object ef- fectively activates/deactivate the light relay of the same group. For exam- ple, in a long corridor this ensures that the light does not go out during the time it takes to walk from the detection zone of one PIR to that of another X X 4 Twilight Switch 5 Twilight Forced Disabled if the "Twilight" parameter is enabled: the light turns on/off according to daylight brightness levels 1 bit (if the "Twilight" parameter is enabled) to deactivate the twilight sensor via the bus so that the device does not send multiple messages on reaching 1 bit the set daylight brightness threshold X X X X C = Communication; R = Read; W = Write; T = Transmission; U = Enable update 161 BUILDING AUTOMATIONS Motion detector: communication objects Twilight function "Twilight function" parameters For automatic power on/off according to daylight brightness levels.

MASTER-SLAVE operation: if you want the light to be turned on by the SLAVE PIRs and turned off by a PIR defined as MASTER, in the relay group you must associate the "Command on movement" object of the MASTER PIR and the "Trigger" objects of the SLAVE PIRs (in which the "command on movement" object will remain unused). Detection performance: the data are approximate (the device is not a LUX measuring instrument) Motion detector: FAQs (20850, 19850, 16850, 14850) 1. The sensor has turned the light on but it does not detect me if I walk in front of it and after a while the light goes off. You need to set a lower value for the "Movement timeout" parameter, which is the delay time before further ON commands are sent if the sensor continues to detect movement 2. Once the sensor has turned oFF the light, it does not turn it on even when someone walks directly in front of it. You need to set a lower value for the "Minimum wait before sending new message" parameter, which is the delay time before further ON commands are sent if the sensor continues to detect movement. 163 BUILDING AUTOMATIONS Motion detector: communication objects ETS reference parameters General You can choose to enable a different device function.
