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.

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
