# Fire Alarm

## Info

## Sequence

### 1. Preparation

1. Initial the OneNote
2. Read about the project specifications and construction type
3. Find Fire Alarm plans (if present)
4. Locate the following rooms:
    * Fire Command Center (FCC)
    * Generator Room
    * Fire Pump Room
    * Elevator Control Rooms
    * Elevator Shafts
    * Stairwells

### 2. Takeoff

#### Fire Command Center

#### Generator Room

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

#### Fire Pump Room

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

#### FACR to Elevator Shafts

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

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

Measure Length from the most distant points of the FACR and each shaft.
Input adder length to reach the bottom of the pit
(Minimum 15ft adder).

```
|           1 shaft           |            2 shafts            |
| || +--------+ +--------+ || | || +--------+ || +--------+ || |
| || | Elev 1 | | Elev 2 | || | || | Elev 1 | || | Elev 2 | || |
| || +--------+ +--------+ || | || +--------+ || +--------+ || |

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

* Measure the Horizontal and Vertical Distance from the FACR to the ECR.
* Use Typicals for the vertical riser. (Ex// 10' per floor)
* Add [[sleeving]] as necessary.

#### FACR to Stairwells

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

`COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`TERMINAL CABINET`/`ACE D ACCESSORY CABINET ENCLOSURE (2) 2" ...`

* _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
* Add [[sleeving]] as necessary.

#### 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

#### 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)

Take off both FA

### 3. Review

* Sleeving
