Walkthrough
If a movement is detected for a time of less than 20 s, the sensor will decrease
the set time delay to 3 minutes. If the set delay time set is already less than three
minutes, it will remain as such.
Eco
The load is switched on manually while switching o is automatic:
- if no movement is detected at the end of the set delay time.
After switching o the load, if any movement is detected within 30 s, the load is
automatically switched back on (retrigger function on). At the end of this time
interval, the load must be switched back on manually.
Detection mode
Set of technologies used for detection.
Initial: set of technologies used for the rst detection.
Holding: set of technologies used after the rst detection.
Retrigger: set of technologies used for the Retrigger function.
After switching o , any new detection within 30 seconds will cause the load to switch
back on automatically. After 30 seconds, the load must be switched back on manually.
Available only in Eco mode.
Alarm: before switching o the load the sensor emits an audible warning signal.
Intervals: 1 minute, 30 seconds, and 10 seconds.

Calibration
To calibrate the sensor, it is necessary to measure the lighting level present using
a lux meter and send the value to the sensor using a con guration remote control
(BMSO4001).
Calibration procedure:
Step 1: with only arti cial light.
Switch the load on at maximum intensity and close the shutters (if you cannot do
this then wait for sunset).
Measure the level of lighting and send it to the sensor via the remote control.
Step 2: with only natural light.
Turn o the load and open the shutters.
Adjustment
This function allows the sensor to switch o the load 10 minutes (plus a safety
threshold to avoid inappropriate switching o ) after the lighting level exceeds the
brightness threshold, even though movement has been detected.
Contribution of light: amount of supplementary light supplied by switching on the
load.
When the contribution of light parameter is set to "auto" the sensor automatically
calculates the contribution of light.
• BMSO4001-088230: advanced con guration remote control
• BMSO4003-088235: simpli ed con guration remote control
When the sensor receives an IR command from a con guration remote control, it
beeps to con rm that the modi cation has been acquired.
For more information on the parameters please refer to the technical info sheet of the
remote control BMSO4001.
Return to factory settings:
1st press: Brie y press LEARN, the LED will blink slowly.
2nd press: Press and hold LEARN for 10 seconds until the LED ashes quickly.
