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
|
|
|
|
"LV Cable" is [[twisted-pair-cable]]
|
|
|
|
#### 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 proximity to switch or occupancy sensor)
|
|
??
|
|
|
|
#### Homeruns
|
|
|
|
Takeoff 1 circuit homerun per lighting zone.
|
|
|
|
### Wattstopper
|
|
|
|
PDI default configuration
|
|
|
|
#### Room Controllers
|
|
|
|
For all rooms with dimmable fixtures
|
|
and/or automatically controlled receptacles,
|
|
take off (1) of either or both as appropriate.
|
|
|
|
`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/`DLM LTG RM CONTROLLER - ...`
|
|
|
|
`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/`REC PLUG CONTROLLER - ...`
|
|
|
|
Takeoff normal power to the controlled load
|
|
* Add LV cable to fixture branch
|
|
* Use \#12/3 for controlled receptacles
|
|
|
|
Takeoff rough-in for both the occ sensors and the LV switch
|
|
|
|
`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/`... LV SW - WALL ROUGH IN ...`
|
|
|
|
`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/`... SENSOR LOW VOLTAGE - ROUGH IN ...`
|
|
|
|
* 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
|
|
|
|
`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/`DLM LTG RM CONTROLLER - ...`
|
|
|
|
??
|
|
Run free-air down corridor
|
|
??
|
|
|
|
* **Length** = Length of 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.
