is it mandatory to install sprinklers and speakers for fire evacuation in workers accomodations?
Your question is to broad with a lot of variables involved
if you want to restate
if existing building probably not.
a brand new building, not built yet, depends
New building ... 5 floors above ground... 1500 workers
Will have to look at 101
Do you know what edition/ year 101 is adopted??
is it all business office??
No other type of use??
NFPA 1: Automatic sprinkler systems, where required. #FireCodefridays
Sleeping areas 1st to 4th floors
Amenities at ground
And worshops at 3 basements
With just that description
yes fire sprinklers
yes fire alarm system
So how long a stay would it be for the average person
What kind of workshop? What do they do??
Is this Mentally/ physically handicap living and work????
It would be interesting why you couldn't find the requirements in NFPA 101?
If NFPA 101 is the adopted code in your area, you should be consulting with it as to when the fire protection systems are to be installed and what additional occupant based requirements that apply to your particular situation. Simply depending on someones simple answer may be a big mistake. Be cautious of the responses of someone on some forum that is not intimate with the project's design. Investigate the details yourself with the designer of the building and come to you own conclusions. Trust me you will be better off.
I am just asking since it is not much clear for me in the nfpa
This will be a labor camp where the workers will go to site in the morning and return to sleep at night.
Duration of stay will depend on the works to do.
Workshops will be steel and wood workshops
Ok, need to do a little 101 research
But appears fire sprinkler and fire alarm will be required.
Is this in the US???
I guess sprinklers are required but am not sure if a voice evacuation system is needed as well
Still need to look at 101
Voice evac should not be required
Just audio visual through out, the entire building.
Plus depending on what year of NFPA 72 is adopted,
might require “ low frequency sounders” in the sleeping areas.
So how are you connected with this project
Using 2015 101
With the limited info appears:
Calling it a chapter 28 apartment or dormitories
18.104.22.168 Requires a fire sprinkler system
22.214.171.124 Requires a fire alarm system, and appears just normal audio visual devices throughout, and possibly smoke detectors in the corridor.
The sprinkler and fire alarm would also be required to be through out the building, to include the work shops.
Just briefing through 101, appears this is the close answer.
Thank you ... that what i concluded as well... but for me evacuation system using speakers and fire fighting telephone are not clear when i read the nfpa
Here is a presentation to help you navigate NFPA 101:

After you have found the code sections that may apply to your situation, then please ask the questions so we can have meaningful discussion.

There is nothing to prevent installing a voice evacuation system in your building. I consider voice-based systems better alternatives to buzzers and horns. A voice is typically less frightening to cause panic, and can give specific instructions.
NFPA 101 requires you to install voice evacuation systems in certain types of buildings. It defines assembly occupancy as including, but not limited to, "all buildings or portions of buildings used for gathering together 50 or more people for purposes as deliberation, worship, entertainment, eating, drinking, amusement, or awaiting transportation."
More specifically, voice evacuation applies only to Class A and Class B assembly facilities that house more than 300 people. NFPA 101, Section 8-3.4.1 states that all Class A and Class B assembly occupancies and art theaters with more than one audience-viewing room shall be equipped with an approved fire alarm system. Other requirements include:
• Occupant notification shall be by means of voice announcements, either prerecorded, or initiated by the person in the constantly attended location.
• The announcement shall be made via an approved voice communications or public address system, provided with an emergency power source above the ambient noise level of the assembly occupancy.
• The authority with jurisdiction determines if it's "impractical to have a constantly attended location" and allows installation of a manual pull station-type fire system.
• Emergency voice alarm/communication systems are a requirement in high-rise buildings more than seven stories.
