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.

Annunciator Panels
[!info] Also Known As
- Fire Alarm Annunciator (FAA)
- Fire Alarm Annunciator Panel (FAAP)

- 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.
