# Fire Alarm Takeoff
|
|
|
|
> [!important]
|
|
> Complete [[conest-emergency-systems-research]] before beginning takeoff.
|

|
|
> [!info]
|
|
> This note is intended for practice specific to [[pdi-estimating]].
|
|
> 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.[^1]
|
|
* _Mid Rise, High Density (Wood frame):_ Free air, conduit only where required.

## Devices
|
|
|
|
Takeoff should always(?) use the
|
|
`DOES NOT INCLUDE COST OF DEVICES AND CABLE` assemblies,
|
|
since we will always(?) have a fire alarm quote.
|
|
|
|
### Smoke Detectors
|
|
|
|
1. `COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`INITIATING DEVICES WITH WIRE - ...`/`SMOKE DETECTOR W/ BASE - ...`

|
1. `COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`INITIATING DEVICES WITH WIRE - ...`/`PULL STATION - ...`
|
|
* **Count:** As shown, otherwise (1) every stairwell at every level and every exterior exit.
|
|
|
|
### Flow/Tamper Switches
|
|
|
|
1. `COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`INITIATING DEVICES ...`/`ADDRESSABLE DUAL MONITOR MODULE - FLOW/TAMPER - ...` (No free-air)

1. `COMMON ASSEMBLIES`/`FIRE ALARM & DAS SYSTEMS`/`INDICATING DEVICES WITH WIRE - ...`/`MAGNETIC DOOR HOLDER - ...`
|
|
* **Count:** As shown, otherwise (2) 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[^2]
|
|
* every elevator lobby, and
|
|
* every BOH room on the first floor and garage levels.
|
|
|
|
[^2]: $\pi(\frac{75}{2})^2 \approx 4415$
|
|
|
|
_Design Build (alternative method):_
|
|
* 15ft from end of corridor,
|
|
* then every 50ft

## Fire/Smoke Dampers (FSD's)
|
|
|
|
> [!info]
|
|
> Refers to fire, smoke, and combination fire/smoke dampers.
|
|
|
|
In [[pdi-building-types#High Rise|high-rise construction]],
|
|
usually found on every level with units.
|
|
|
|

|
|
> If possible, use
|
|

|
|
|
|
For each damper, take off both
|
|
|
|
1. * `System` = "FA - Fire Alarm"
