SensorView Terms
100 Hour Burn-In: Overrides relay on and/or dimming output to full bright (typically
used for lamp seasoning)
Auto Set-Point: Photocell calibration procedure for detecting optimum lighting control
level
Auto to Override On: Special Mode where lights are turned on initially by occupant
detection but then left in the Override On state
BACnet Instance (Number) A device’s instance number is used to uniquely identify
nLight devices connected to BACnet.
The instance number is combined with other parameters in BACnet, such as Object Type
or Object Name. Because BACnet services many facilities and many different companies,
the instance number compensates for and eliminates any possibility of duplicate
identifiers across the BACnet network. It is similar to the WHOIS function for domain
names on the Internet. Requesting devices across the network can identify the device,
its address information and its relative position in the network hierarchy. More
information on BACnet Instance Numbers.
BMS (Building Management System)
A Building Management System (BMS) is a network which monitors and/or controls
devices in a building, campus, or in multiple facilities.
When used for monitoring, the BMS polls and displays information from various types
of equipment. BMS may monitor alarm conditions for equipment dependent up
humidity or temperature. SensorView polls nLight devices, for example, and collect
sensor information on occupancy, light levels, microphonic activity, among others.
When used as a control system, the BMS has the ability to change settings on
networked devices. This can be done manually by facilities/BMS managers, or by pre-
programmed conditions, where settings of devices are modified in response to readings
collected by other networked devices. Slave devices pass data from sensors to the
master, which processes collected data and issues instructions for any necessary
settings changes. Instructions can also be issued to devices based on Profiles which may
be scheduled to start at a certain time of day, or triggered by readings and thresholds of
other devices. nLight products integrate with BMSs using Internet protocols and open
standards such as BACnet.
Broadcast Analog Input: Input mode that senses a 0-10 VDC input
Button Mode: Overrides a device and enables its push-button to toggle the device’s
internal relay(s) or dim level
Dimming Offset: Fixed voltage difference of dimming output from dimming photocell
