Within a Medical/office type building. Approximated at 30,000sq ft. with a full sprinkler system. Smoke detection in all common hallways.

Does individual suited need smokes in corridors and in each exam/office rooms etc.

On drawing shows only a pull station at front door with horn/strobe above. Plus one horn/strobe in rear hall. One heat detector and strobe in bathroom only. I dont see no smokes at all. I am curious if any are needed and even more curious which rooms if not all need them. Where to you read to draw the line here.
 
Can I assume that your working on the "common area's" and maybe one tenant space?

If your building is to later be sub divided for tenants then your correct in only appling a Pull Station and Strobe
as you described it seems your only appling the common area with the F/A wire and devices. All Space's should have one Pull station and strobe.

Once the additional spaces are rented there design will (should) include the all the additional requirements for cover F/A and sprinkler requirements.
It will add and even change your own install with the construction around a doorway.

Depending on your AHJ rules you can read up on.

NFPA 72: National Fire Alarm Code 2007 or 2002, or
NFPA 13: Standard For the Installation of Sprinkler Systems, 2007

You beat me to it.

Also check with your local AHJ. Fire alarms are one of those things that don't really have a "national" standard or rules. Each jurisdiction usually gets to dictate what the requirements are.
 
Tenant space only

Tenant space only

This install is for only a suite fitout. All smokes/pull/strobes exist. Just need to understand in the suite only that has sprinklers. Do i install in all rooms?

It shows only one heat detector in bathroom and a strobe. One pull station at front door and horn/strobe. And one horn strobe in rear hallway. It shows no smokes what so ever. I am not sure if it even needs any due to sprinklers. Or does every room need one. Once again their shows no smokes at all in suite just items listed above.

Depends on the AHJ and their requirements. Ask first or you might end up with a huge change order.

I guess I need clarification, is a suite a sleeping quarter or is this just like offices?

I believe sleeping room require smokes in addition to sprinklers, but office spaces do not. But like said before AHJ will have the final say.
 
1. Find out what code is adopted in the jurisdiction.
2. Find out the occupancy classification and occupant load of the building.
3. Find out if, when, and by who the original installation was permitted to.
4. Call the fire authority (AHJ) and discuss the existing coverage and what is to be required moving forward.

Working with fire alarm systems requires a lot of research and coordination with fire authorities. Never make assumptions and always get the facts. Good luck with your project.
