Im needing to understand the suite boundary and how does it applies? 618 is an auto slider, 707,708,711,715(Auto Doors). Inspector is saying Suite Boundary for all doors now
I couldn't determine how in the world the inspector could have found any suite of rooms from this drawing. Just not enough information.
In life safety drawings, the surveyor looks for:
The surveyor notes that an organization needs to be able to speak to the purpose of each rated barrier, and must be able to differentiate between the following rated barriers:
It appears from the drawing the rooms accesses an exit access corridor so the doors mentioned in your question (707,708,711,715) may be corridor doors meeting the latching and smoke resistance requirements of the Life safety Code.
The first thing you need to do is show the exit access corridors on your drawings (highlight in yellow). Exit access corridors are those that directly access at least two exit doors without passing through intervening rooms. Then where you have groups of rooms that do not have doors into the yellow corridors, they are a suite of rooms. Those suites are required to be bounded by construction equal to the required corridor wall construction including smoke resistance doors with positive latching hardware. I would look to see if the automatic power doors have positive latching hardware.
A suite of rooms is an alternative to having room doors directly accessing an exit access corridor.
A suite can be thought of as a large room with partitions that subdivide it into smaller spaces. To most individuals, a suite may look like a hallway with rooms opening into it. But from a Life Safety Code perspective, a suite is much different from a corridor and rooms. Rooms and corridors within a suite are not subject to all of the requirements for corridors or individual patient rooms.
The improper designation of suites poses a significant increase of risk to patients by encouraging increased risk due to additional storage and equipment. Properly designing, constructing, and maintaining suites allows for increased levels of life safety protection while allowing for increased storage and equipment use that can improve patient care.

Deficiencies and Eqivalencies
Your drawing appears to be a portion of a fairly large OR department. This type of hospital area can be a bit complicated due to the different functional areas that typically may be associated with OR as well as the need to establish and maintain sterile areas.
From a LSC perspective most any arrangement of rooms that is larger than a single room could potentially be designated as a suite of rooms. There are various LSC code provisions based upon whether or not the suite is sleeping rooms or non-sleeping rooms with corresponding limitations on size, travel distance, number of exit access doors required, etc., etc.
Without seeing the floor plan for the entire floor of the building it would be extremely difficult to give you guidance on which areas might potentially be designated as a suite. Generally we first have to start with looking at the entire floor, building limits, the total square footage, the number and location of smoke barriers, corridors, and horizontal exits and/or exit stairs. Once the footprint of the floor has been evaluated to meet LSC requirements then rooms and use areas that open off of the means of egress corridor can be marked off either as individual rooms or suites of rooms up to the limitations allowed by the LSC.
In the question you pose I'm not clear on what your inspector is saying about suite boundary doors or which doors would be included. In your question you listed several doors (707, 708, 711, and 715) which together could potentially form part of the boundary of a suite. To complete the suite boundary it would appear door 710 should also be included in this list. Im also guessing some other use areas on this floor could also be designated as suites as well.
From what I can see on the section of drawing provided it is not likely door 618 would be included as part of a suite, but may serve another role in the bigger picture of the building/floor as a whole.
Lawrence, thanks for response please see below email.
You didn't respond if we helped you. We took the time to research and respond to your question and would like to have a response from you. Were our comments of any help at all?
I have some additional information on the subject for those viewing the thread.
Back to your question: I'm needing to understand the suite boundary and how does it applies?
This video provides a basic understanding how the suite is applied in a hospital. I feel the graphic presentation was very helpful to those who have problems envisioning the code requirements. Marty through his design background does wonderful job explaining the concepts. There are more videos about suites on his site that may interest you.
