Controls Sequence of Operations

Typical Sequence of Operations for Lighting Control Systems

Lighting controls always seem to be a bit of a moving target, with technologies and codes changing rapidly. We always recommend providing a general narrative in your plans or specs for how the system should function. This helps us to fill in the gaps with all the appropriate parts and pieces to ensure your sequence of operation (SOO) is met.

Below we have provided some standard SOO’s that we see from project to project. Please reach out to us if there are any space types you would like added, or if you have any questions on what we’ve put together so far. You can also download the complete PDF document at the very bottom of this post.

Interior Spaces

General
Provide override switches as shown on plan. Owner shall have the ability to adjust and save scenes, and adjust timeclock schedules via touchscreen or software application.

Provide photocell and daylight harvesting programming wherever a daylight zone exceeds 150W of lighting. All private offices, storage rooms, conference rooms, and any room less than 300SF shall be provided with vacancy sensor. Provide dimming [A/B switching] for all site lighting between the hours of 10pm and 6am.

-OR-
Provide UL924 rated transfer device for all emergency fixtures shown with zoning tags. Emergency fixtures shall be controlled with normal, until loss of power, when fixtures are required to go to 100% output. [Generic note once zoning is shown on plans]
-OR-
All emergency fixtures shall be unswitched nightlights.
-OR-
Fixtures are provided with integral batteries. UL924 devices are not required.
