Description
Sensor walk test LED
Disable
Enable
Enable or disable the sensor walk test LED, triggered
when movement is detected. This is useful for
commissioning, (or if the detector is to be used in
bedrooms). Note that the walk test function can also
be turned on and off via infra-red remote control.
Sensor sensitivity
0 to 9
Increase or decrease the detector's sensitivity to
movement. 0 is least sensitive, 9 is most sensitive.
The sensitivity can be overridden via infra-red
remote, but will be overwritten when parameters are
updated via ETS.
Movement timeout
0 to 65,535 seconds
How long to wait after the last movement is detected
before signalling a 'movement cleared' state.
Lux multiplier
Floating point
Value to multiply raw light level readings by to obtain
true lux value. In practice, this will need to be set with
the aid of a light meter in the environment that the
detector is used in, as reflected light and even choice
of furnishings will dramatically affect the readings
obtained.
Send light level telegrams every
0 – 65,535s
Defines how often to send light level telegrams. It is
only possible to send cyclically: immediate
transmission would overload the bus.

Description
Light Level Output
9.4 DPT_Value_Lux
Simple cyclical output of current brightness in lux.
Basic movement detection
The basic movement detection parameters are designed to provide raw access to the movement sensor itself.
Movement detection by this function is not affected by the movement timeout parameter in the General parameters
settings section – i.e. an telegram indicating an absence of movement will be sent relatively quickly.
'For operation as a slave device in a multi-sensor environment, it is necessary to configure the sensor to send an 'on'
command when movement is detected. There is no need to configure the corresponding 'off'
command, as this timeout is handled by the master detector. The switch state group object should be linked with the
corresponding slave input on the master detector.'

Send cyclical telegrams every
0 – 65,535s
Defines how often to send switch state telegrams if
cyclical sending has been chosen.
