Standpipe or Not?

Not typical for stairway standpipes

We were recently going through a large senior residential occupancy. This occupancy has 7 wings and several different stairwells.

Not all of the stairwells have standpipes in them. áMost were typical connections with a valve and 2 1/2 inch connection. As you can see in this picture, this one was not a typical seen in a stairwell.

At the left of riser you can see the standpipe connection. áThey basically put the sprinkler room in the stairwell.

If you weren’t familiar with this, a person might just start turning valves or just think that there is not a standpipe connection at all.

The point here is that not all standpipe connections are created the same. Nor are all sprinkler rooms in a closet.

Get to know your buildings and the systems that operate in them. You never know when you will need to use them.

    This is somewhat common setup in my city. Usually they’re found in the ground floor or parking garage stairwell or access. I agree it could be confusing if you’re not sure what you’re looking for. The facility description you mention brings to mind one particular occupancy we hav…3 8-story towers, common underground parking, each bldg. with its own sprinkler and standpipe FDCs, 6 stairwells, each with a standpipe outlet/H20 shutoff valve, almost total elderly population. The one saving grace is that their managers and maintenance heads live on-site and are very organized with all the protection system information in one main alarm room. The other plus is that we tend to run a good amount of EMS and fire alarms there, and crews are constantly reviewing the layout/systems.

    This building is not that tall, but has several stairwells. But, not every stairwell has standpipes. There is no parking garage and this is on the ground level, center stairwell.

    Does anyone know if systems set up such as this one are more likely to have internal pressure-regulating devices, since the sprinkler and standpipe systems are integrated? Certainly might be something you’d have to ask some questions about in order to be prepared.

    Hey, great question and I will try to find out. Thanks.

  • Mike Morton says:

    I’m no plans review expert or anything, but I would think there’d be some sort of pressure regulation since the sprinklers and standpipes are not designed to operate at the same pressures, yet share risers and water supplies. I’m interested to see what you find, and I’m going to inquire as much as I can the next time I see a similar setup.
