The table below lists the commands supported by the Lighting Output Object.

For the Release Operator Override, Release, and Release All commands, if all Command Priorities have been released and a Relinquish Default is not defined, the supervisory controller gives control to the actual hardware.

Table 1. Lighting Output Commands
Command Name	Parameters	Description
Adjust	Value	Releases Command Priorities 9 through 15 (Scheduling) and then writes to the Present Value at the Default (16) command priority. The percentage must be less than Max Actual value and greater than Min Actual Value.
Disable Alarms	None	Disables all types of alarming: alarm extensions, BACnet intrinsic alarming, and BACnet Event Enrollment objects.
Enable Alarms	None	Enables all types of alarming: alarm extensions, BACnet intrinsic alarming, and BACnet Event Enrollment objects.
Fade To	Value Fade Time	Sends a Fade To BACnet lighting command to the object. Specify a percent value (target level) and a fade time in milliseconds.
Operator Override	Value	Updates the Present Value at Command Priority Operator Override (8). The Operator Override command sends the specified command to the internal engine object, which is then only sent to the field device when not Out Of Service.
Ramp To	Value Ramp Rate	Sends a BACnet lighting command to the object in which the Present Value of the Lighting Output object is ramped to a target level by percentage. Specify a percent value (target level) and a ramp rate in percent per second.
Release Operator Override	None	Releases Command Priority Operator Override (8) from Present Value.
Release	Attribute Priority	Releases the identified Command Priority from the specified attribute and allows the next highest priority to control it.
Release All	Attribute	Releases Command Priorities 3 through 16 (Default), from the specified, writable attribute. Command Priorities 1 and 2 remain. Important: The Release All command may not cause an immediate return to automatic operation. The Release All command clears all command priorities, including those that come from applications and features. When this happens, the output point goes to its Relinquish Default condition. In some cases, the application or feature may have sent a command that does not match Relinquish Default. In this instance, the output point does not end in the state that the applications or features intended. This situation can cause unexpected operation to occur; for example, a space could overcool or overheat, a fan might run longer than expected, and so on. If an operator has overridden an input, use the Release Operator Override command.
Step Down	Step Increment	Sends a BACnet lighting command to the object in which the Present Value of the Lighting Output object is decreased by one step. Specify a step increment in percent.
Step Off	Step Increment	Sends a BACnet lighting command to the object in which the Present Value of the Lighting Output object is stepped off by one increment. Specify a step increment in percent.
Step On	Step Increment	Sends a BACnet lighting command to the object in which the Present Value of the Lighting Output object is stepped on by one increment. Specify a step increment in percent.
Step Up	Step Increment	Sends a BACnet lighting command to the object in which the Present Value of the Lighting Output object is increased by one step. Specify a step increment in percent.
Stop	None	Sends a BACnet lighting command to the object in which any ramping of the Present Value of the Lighting Output object is stopped immediately.
Temporary Override	Value, Hours, Minutes	Overrides a point temporarily for a specified period of time. Specify a value in percent, with hours and minutes. After the specified time period passes, the Override is automatically released.
Warn	None	Sends a blink-warn notification to the Lighting Output object at the specified priority.
Warn Off	None	Sends a blink-warn notification to the Lighting Output object at the specified priority, then sends a 0.0% command to the controlled lights after a delay specified by the Egress Time.
Warn Relinquish	None	Sends a blink-warn notification to the Lighting Output object at the specified priority, then relinquishes the value to the controlled lights after a delay specified by the Egress Time.
