Description
Detection parameters
LED operation test
Off
ON or Off
When this option is activated, a red LED on the sensor flashes when it detects
movement. Use this function to check that the sensitivity levels are suitable.
Timeout
20 minutes
0 to 99 minutes
Once the detector is turned on, this value sets how long the lights will stay on once
movement has ceased. Select 0 for a 10-second period (for commissioning only).
Manual timeout period
10 minutes
0 to 99 minutes
When a manual operation occurs, either via the switch input or the infrared, it
invokes the timeout period.
Example 1: a detector in presence mode has a detector timeout of 15 minutes and
a manual timeout of 3 minutes. When the user leaves the room, they press the off
button. The sensor will revert to automatic mode after 3 minutes, then walking
back into the room will turn the lights on.
Example 2: using the settings above, the user turns the lights off (say for a
presentation) but stays in the room. Every time a movement is detected, the
manual timeout period is re-triggered, but if it doesn’t pick up over a short period,
the detector will revert to automatic mode. This means that the lights may come
on inadvertently during the presentation, even if the occupants are still present
during the manual timeout period, so adjust the timing carefully.
Sensitivity On
9
1 (min) to 9 (max)
Sensitivity level for detecting movement when the detector is already on.
Sensitivity Off
9
1 (min) to 9 (max)
Sensitivity level for detecting movement when the detector is off.
Lux time
0
0 (disabled)
1 to 99 minutes
If the detector measures the Lux level and decides that the output needs switching
on or off as a consequence, the Lux time must elapse first. If at any time during the
timed delay the Lux change reverses, the process is cancelled. Lux time enables
absence detection to be implemented with a Lux Off level set. When the button is
pressed, the lights will go on, regardless of ambient light level. However, if there
is sufficient ambient light, they will turn off again after the Lux time. Note that
whenever an external switch is pressed, whether in absence or presence mode, if
the lights were out because of the Lux level, they will be immediately turned on
again for at least the Lux time.
Power-up state
On
On or Off
Select Off for a 30-second delay on start-up. If On is selected, there will be no delay
on start-up and the detector will always power up detection.
Factory default
-
-
Restores the factory default settings.
User Mode
Override On
-
-
If the lights are off, sending the IR command will turn them on immediately and
revert to automatic operation after the manual timeout period.
Override Off
-
-
If the lights are on, sending the IR command will turn them off immediately and
revert to automatic operation after the manual timeout period.
Cancel
-
-
Cancels the on or off override, returning the detector to normal operation.
Channel 1 - Switching
Detection mode
Presence
Presence or absence
Presence mode allows the output to turn on when movement is detected and
off when movement ceases. Absence mode allows the output to turn off when
movement ceases, but must be manually turned on first.
Lux On level
9
1 to 9
For a higher
resolution a range of
101-199 is available
Sets a minimum light level below which the PIR sensor is enabled, allowing the
lights to be turned on by movement.
Note: The "Lux Off level" value must always be greater than the "Lux On level” value.
