Fire Alarm

Sequence

1. Estimate 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

Riser

Fire Command Center

{Building Type} Head End CA.30.23.X

Generator Room

CA.30.22.2

Fire Pump Room

CA.30.22.4

FACR to Elevator Shafts

Elevator Shafts (CA.30.22.8)

FACR TO ELEV SHAFT 1 ½" (CA.30.22.10/11)

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            |

FACR to Elevator Control Rooms

Elevator Control Room (CA.30.22.6)

FACR/FCC TO ELEV CONTROL ROOM (CA.30.22.13/14)

• Measure the Horizontal and Vertical Distance from the FACR to the ECR.
• Use Typicals for the vertical riser. (Ex// 10' per floor)

FACR to Stairwells

FACR TO STAIRWELLS 1" PVC (CA.30.22.17)

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

• This is for the Flow/Tamper modules in the stairwells

Terminal Cabinets

TERMINAL CABINETS (2) 2" EMT/PVC (CA.30.26. __)

Horizontal:

• Measure from the Fire Command room to all electrical rooms

Vertical:

• Use 10ft Riser in Typical
• GA or HD - 1" conduit / HR - (2) 2" conduits)

Annunciator Panels

• Fire Alarm Annunciator (FAA),
• Fire Alarm Annunciator Panel (FAAP)

ANNUNCIATORS (CA.30.27.2/3)

Remote Serial Annunciator, LCD Display - PVC

• Measure from the Fire Command Room to FAA or Lobby

Sleeving

Devices

1. Takeoff floor plans in order
2. Takeoff enlarged drawings

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

Mech Connection - PVC AL Flex - 20 A

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.

Fire Smoke Dampers (FSD's)

Take off both FA and Electrical

• Misc Assemblies

Area of Refuge (AoR) / Two-Way

PROPOSAL "STAND ALONE SYSTEMS"

CA.31.27. 4/7

Horizontal

Take off once

• Length:
  • If shown on Plans (FA/Systems/ etc.)
  • based on FCR to Elevator Lobbies & FCR to Stairwells* (Whichever is longer)
• Count: Number of boxes run to. If not shown, use the largest count between Elev. & Strwlls.

Vertical

Typical on all floors

• Length: 15ft x per count
• Count: match Horizontal
