Fire Alarm Takeoff

Fire Alarm Takeoff

Important

Complete emergency-systems-research before beginning takeoff.

[!info] See fire-alarm for information about fire alarm systems.

Assembly Selection

Free Air < PVC in Slab < EMT

High Rise (Steel & slab): Free air in Units, use conduit elsewhere. Mid Rise, High Density (Wood frame): Free air, conduit only where required.

Backbone

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

Fire Command Center

  1. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/HEAD END EQUIP/... HEAD END

Generator Room

  1. Area = Same as FACR

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

Fire Pump Room

  1. Area = Same as FACR

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

Elevator Control Rooms

Also "Elevator Machine Room"

For each Elevator Control Room (ECR):

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

    • Count = 1
  2. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/GEN, ELEV, FIRE PUMP & FA ROOM ASSEMBLIES/FACR TO ELEV CONTROL RM ...

    • Length = Length measured from the most distant points of the FACR and ECR.
      • Input adder length to reach the level of the ECR (Minimum 15ft).

Elevator Shafts

For each elevator shaft:

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

    • Count = 1
  2. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/GEN, ELEV, FIRE PUMP & FA ROOM ASSEMBLIES/FACR TO ELEV SHAFT ...

    • Length = Length measured from the most distant points of the FACR and elevator shaft.
      • Input adder length to reach the level of the shaft (Minimum 15ft).

[!important] Counting Elevator Shafts Adjacent elevators may be in the same or parallel shafts. Count the shafts accordingly:

|                             |                                |

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

FACR to Stairwells

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

For each stairwell:

  1. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/GEN, ELEV, FIRE PUMP & FA ROOM ASSEMBLIES/FACR TO STAIRWELLS 1" CONDUIT ...
    • Length = Length measured from the most distant points of the FACR and stairwell.
      • Input adder length to reach the level of the stairwell (Minimum 15ft).

Terminal Cabinets

COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/TERMINAL CABINET/ACE D ACCESSORY CABINET ENCLOSURE ...

  • Garden Style, High Density: (2) 1"C
  • High Rise: (2) 2"C
  1. Horizontal:

    • Area = Same as FACR

    ... HORIZONTAL RUN

    • Length = Length measured from FACR to all electrical rooms
  2. Vertical:

    • Area = "Typical - Building All Levels"

    ... RISER

    • Length = 10ft

Annunciator Panels

[!info] Also Known As

  • Fire Alarm Annunciator (FAA)
  • Fire Alarm Annunciator Panel (FAAP)
  1. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/ANNUNCIATORS/REMOTE SERIAL ANNUNCIATOR ...
    • Length = Length measured from the FACR to FAA or Lobby

Central Monitoring Loop

Important

Garden Style only.

Fire Alarm Control Panels from each building will send a signal to a central location.

In case of an emergency, the fire department will go to the central fire alarm station and find out what the issue is.

Devices

Smoke Detectors

  1. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/INITIATING DEVICES WITH WIRE - .../SMOKE DETECTOR W/ BASE - ...

Design Build: Count every stairwell at every level.

Pull Stations

  1. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/INITIATING DEVICES WITH WIRE - .../PULL STATION - ...

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

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

Design Build: Count 2 for every set of double doors. (Typical of elevator lobbies and corridors)

Horns, Speakers, and Strobes

  1. COMMON ASSEMBLIES/FIRE ALARM & DAS SYSTEMS/INDICATING DEVICES WITH WIRE - .../INDOOR HORN STROBE - ...

Design Build (method 1):

  • 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.

Design Build (alternative method):

  • 15ft from end of corridor,
  • then every 50ft

Fire Smoke Dampers (FSD's)

For each damper, take off both

    • System = "FA - Fire Alarm"
