SETTING
All sensor settings can be configured, in individual or group basis, by
an OS-NET Remote Programmer SRP-281. Following table highlights
the setting items and options available with ON-BRD-500. For detailed
setting operation, please refer to the OS-NET Programming Guide
available for download from www.irtec.com.

OPERATION
The ON-BRD-500 employs a digital PIR sensor together with an ALS to detect occupancy status
and ambient light level. The sensor not only controls the connected lighting as programmed
when it detects the presence of an occupant/vehicle, but also broadcasts an OCC signal to other devices of the
group to activate the respective controls. Each sensor can be assigned to be
member of maximum 4 groups for coordinated control.

Scheme Description
ON/OFF This is a typical occupancy sensing control scheme.
Lighting will be inhibited when the ambient light level is higher than the set threshold, regardless of occupancy or vacancy. When
the ambient light level is lower than the set threshold, the controlled light will be automatically turned on once the sensor detects the
presence of occupant, and turned off after the delay time elapsed.
NOTE: This scheme can be used with dimmable or non-dimmable lighting, but not for HID lighting.
OSO This is an occupancy sensing control scheme can be applied in areas that require 24-hour lighting. When space is vacant, the lights
will be maintained at Low Dim level. Whenever space is occupied, lighting output will be increased to High Dim level or continuously
regulated to maintain within the pre-set range by SmartDIM control.
NOTE: Do NOT use this scheme to control non-dimmable lighting.
OSLA This is an occupancy sensing control scheme can be applied in spaces that require automatic lighting when the ambient light level is
lower than the set threshold.
Lighting will be inhibited if the ambient light level is higher than the set threshold, regardless of occupancy or vacancy. When the
ambient light level is lower than the set threshold, the sensor will automatically control the light at Low Dim level. When sensor detects
the presence of an occupant, lighting output will be increased to the High Dim level or continuously regulated within the pre-set range
by SmartDIM control. After the delay time elapsed, lighting output will be reduced to Low Dim level or shut off if the ambient light is
higher than the set threshold.
NOTE: Do NOT use this scheme to control non-dimmable lighting.
OSLATO This is an occupancy sensing control scheme can be applied in spaces that require maintaining Low Dim lighting for a period of time
before shutting off.
Lighting will be inhibited if the ambient light level is higher than the set threshold, regardless of occupancy or vacancy. When the
ambient light level is lower than the set threshold, and any sensor detects the presence of occupant, lighting output will be increased to
High Dim level or continuously regulated to maintain overall lighting level within the pre-set range by SmartDIM control. After the delay
time elapsed, lighting output will be reduced to Low Dim level for a period of TIME OFF delay before shut off.
NOTE: This scheme requires dimmable lighting to enable dimming control. If lighting is non-dimmable , there will be no dim control
and the delay time will be extended with the TIME OFF (TO) delay.
DSVM This is a daylight sensing control scheme can be applied in spaces that require automatically dimming the lighting output to a low
level between a certain time before and after virtual midnight.
Lighting will be inhibited if the ambient light level is higher than the set threshold. When the ambient light level is lower than the set
threshold, the sensor will turn the light to High Dim level or continuously regulate the output to maintain overall lighting level within the
pre-set range by SmartDIM control. Lighting output will be reduced to Low Dim level from a certain time before virtual midnight to a
certain time after.
NOTE: This scheme requires dimmable lighting to enable dimming control. If lighting is non-dimmable , all lights will remain on
whenever ambient light level is lower than the set threshold.
DSC This is a daylight sensing control scheme can be applied in spaces that require automatic lighting whenever the ambient light is lower
than the set threshold.
The sensor will automatically turn on the light to High Dim level or continuously regulate the output to maintain overall lighting level
within the pre-set range by SmartDIM control when the ambient light level is lower than the set threshold, and automatically turn off the
light when the ambient light level is higher than the set threshold.
NOTE: This scheme requires dimmable lighting to enable dimming control. If lighting is non-dimmable , all lights will remain on
whenever ambient light level is lower than the threshold.
VSC This is a vacancy sensing control scheme can be applied in spaces that require users to manually turn on the light, and have the
sensor turn off the light automatically.
The occupant would have to press the OS-NET Button to turn on the lighting group assigned. The sensor will control the lights at High
Dim level or continuously regulate the output to maintain overall lighting level within the pre-set range by SmartDIM control. The sensor
will control the connected lighting as per OSLATO scheme.
NOTE: This scheme requires dimmable lighting to enable dimming control. If lighting is non-dimmable , there will be no dim control
and the delay time will be extended with the TIME OFF (TO) delay.
OSB This is an advanced occupancy sensing control scheme can be applied in open offices to provide background light level before the
area of entire lighting group is vacant.
Lighting will be inhibited if the ambient light level is higher than the set threshold, regardless of occupancy or vacancy. When the
ambient light level is lower than the set threshold and the first occupant is detected by a grouped sensor, the output of sensor
connected light will be increased to High Dim level or continuously regulated within the pre-set range by SmartDIM control during
occupancy, and the unoccupied areas of entire lighting group will brighten up to Low Dim level as background light. The entire lighting
group turns off after the last person leaves and delay time elapsed.
NOTE: Do NOT use this scheme to control non-dimmable lighting.
OFF This is a manual control scheme can be used when you need the light to be off for a certain period of time.
Once this scheme is set, all OS-NET controlled lighting will remain off until another scheme is selected.
