## Backbone

Put all backbone takeoff in the `Area` of the Fire Command Center.
Include [[sleeving-takeoff]] as necessary.

* Measure the Horizontal and Vertical Distance from the FACR to the ECR.
* Use Typicals for the vertical riser. (10ft per floor)

### FACR to Stairwells

> [!info]
> This is for the Flow/Tamper modules in the stairwells

`COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`GEN, ELEV, FIRE PUMP & FA ROOM ASSEMBLIES`/`FACR TO STAIRWELLS ...`

* Measure from the furthest end of FACR to the furthest end of the stairwell to find length

### Terminal Cabinets

* _Garden Style, High Density:_ (2) 1"C
* _High Rise:_ (2) 2"C

Horizontal:
* Measure from the Fire Command room to all electrical rooms

Vertical:
* Use 10ft Riser in Typical

### Annunciator Panels

> [!info] Also Known As
> * Fire Alarm Annunciator (FAA)
> * Fire Alarm Annunciator Panel (FAAP)

`COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`ANNUNCIATORS`/`REMOTE SERIAL ANNUNCIATOR ...`

* Measure from the Fire Command Room to FAA or Lobby

## Devices

### Smoke Detectors

_Design Build:_
Count every stairwell at every level.

### Pull Stations

_Design Build:_
Count every stairwell at every level
and every exterior exit.

### Flow/Tamper Switches

No free-air. If wood frame, take off as EMT.

_Design Build:_
Count every stairwell at every level.

### Magnetic Door Holders

`COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`INDICATING DEVICES WITH WIRE - ...`/`MAGNETIC DOOR HOLDER - ...`

_Design Build:_
Count every set of double doors.
(Typical of elevator lobbies and corridors)

### Speaker Strobes

_Design Build:_
* Count every 75 ft,
    * measure with circles on Bluebeam
    * or divide relevant SF area by 4415
        * $\pi(\frac{75}{2})^2 \approx 4415$
* every elevator lobby,
* and every BOH room on the first floor and garage levels.

## Firefighter Phone System

* firefighter phone jacks
* fire warden station
* fire phone cabinet

Communicates directly with FACR.
Not related to responder radio.

## Fire Smoke Dampers (FSD's)

For each damper, take off both

`System` = "FA - Fire Alarm"
