# Lighting Controls Takeoff

> [!info]
> See [[lighting-controls]] for more on lighting controls systems.

> [!info] "Local Control" as a PDI proposal qualification
> The term "local control only" is sometimes used to indicate
> no consideration for _any_ lighting control beyond standard devices,
> (with `$D`'s being the triac type)
> however, this phrasing is ambiguous and non-universal.
> Confirm with [[pdi-estimating#Bid Estimating|bid team]] on what must be included.

Determine which Systems and Codes are required:
* _IBC/IECC 2021 or later:_ all fixtures 0-10V dimmable.

## PDI Lighting Control Configurations

### Stand Alone

0-10V dim -- "LV cable" is 2 conductor

Takeoff rough-in for switches and occupancy sensors
* **Branch Length** = length of room

Takeoff the lighting control relay (DLM)

Takeoff an additional controller if receptacles are controlled

Takeoff homeruns to the DLM (one per controlled circuit)
* Note: Not necessarily per room, several rooms may share a lighting circuit.

### Networked

#### Devices

##### Room Controllers

No room controllers are necessary,
lighting zones are switched from a central lighting control panel (LCP)

##### Switches and Sensors

Takeoff rough-in for switches and occupancy sensors

??
(only if time based; length based on closeness to sw/occ sensor)
??

#### Homeruns

Takeoff 1 circuit homerun per lighting zone.

### Wattstopper

PDI default configuration

Takeoff (1) DLM controller for the fixtures
and (1) Plug controller for the receptacle
* If room has both dimmable fixtures and the controlled receptacle,
  only (1) DLM controller and (1) Plug controller
* Use MC to cover room if drop
* Use EMT if exposed or MC not permitted

Takeoff normal power to the controlled load
* Add LV cable to fixture branch
* Use 12/3 for receptacles

Takeoff rough-in for both the occ sensors and the LV switch
* Free air if possible
* **Length** = length of room

Cat cabling from the controllers on is likely provided by systems
* Confirm with chief or quote language

#### Corridor Occupancy Sensors

If occupancy sensors are shown in the corridors:

Takeoff homerun back to the electric room

Takeoff (1) DLM controller for each electric room
* Run free air down corridor

Takeoff rough-in for each occupancy sensor shown.

#### Network Bridge

Check systems quote to determine if network bridges are needed.

Takeoff (1) back box for every ==group of rooms you want together==

??
If not showing, put one in every room with a controller
??

#### Homeruns

Need a HR into the room for the controllers
* Can link multiple controllers (aka rooms) together if you have the same circuit
* Go back to closest electric room

## Custom Switch Boxes

For switch combinations not in `COMMON ASSEMBLIES`,
create [[heating-designations]] based on the most similar.
