Does a Sauna room require fire alarm notification?
Is there any code requirement on this one way or another? Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

Before people say, "Ask the AHJ," I am him; he is me.
I have an applicant who has combined plots of land with a mid-rise and some detached townhouses. A shared fire line supplies the two structures, but only the mid-rise FACP monitors the supply tamper. The townhouse FACP will not know if the water is off (except for the tampers at the risers within the townhouse). The buildings are owned by the same ownership. They are arguing they are technically meeting IBC 2015 903.4 "Valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels, and temperatures, critical air pressures, and waterflow switches on all sprinkler systems shall be electrically supervised by a listed fire alarm control unit." It is being monitored, but the fire marshal and I are of the opinion this doesn't provide monitoring for the townhouse and does not meet the intent of the code. Does anyone have any thoughts on whether a shared line can be monitored by only one building that it serves? Sent in anonymously for discussion.

I would like to include the testing requirements in the statement of work. I looked through NFPA 72-19 Chapters 14 and 26, as well as other chapters and codes. I do not see the requirements for central station headend testing. I think the subscribers will need to ping the central station with the date, emergency code, building, etc. Does code require a minimum amount of information the subscribers must send to the Central Station? If so, could you tell me the required subscriber information that needs to be sent to the central station or provide the location in code for the information to be sent to the central station from the subscribers? I don't see any requirements or criteria for testing, and I want to be sure we're conducting this appropriately. Thanks in advance. Sent in anonymously for discussion.

Alternatively, removing the detectors can be considered in this situation. Looking for relevant code and standard basis. We're under the 2021 IFC, 2021 IBC, and 2019 NFPA 72. Thank you!

The required smoke detector outside the elevator door, installed under the soffit overhang, will quickly fill with dust/dirt. Any thoughts about using a heat detector at this spot that ties into the elevator recall requirement? I am the AHJ. Thank you. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe I hear so many times that if the fire alarm panel dies, the entire building's fire alarm system must be brought up to current code.
Can anyone educate the world on when building fire alarm systems must be completely upgraded to the current code? The International Existing Building Code (IEBC) Section 6 lists all possible combinations. Level 1, level 2, and Level 3. None of them require a full upgrade to the current code when the main panel hits its end of life. If a system was to need to replace all items in its location with a different system, reusing locations and wire, it would not meet a Level 3 requirement alone and would simply be using new equipment or fixtures that serve the same purpose. Can someone give me an actual code path that requires a full upgrade in this scenario? Thanks in advance. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe I have an R-2 convent with existing 120v smokes in the sleeping areas and they are installing a new FACP including low frequency notification in the sleeping areas.
I’ve read the commentary for IBC 907.5.2.3.3. Would you say based on this section that they would need to either replace the existing 120’s and install system smoke detectors, or change the existing 120’s to a combo audio/visual model? I'm trying to determine if the intent behind this is that the existing 120v smoke alarms now would also be required to activate visible signaling as well. Appreciate your input!

Click Title to View | Submit Your Question | Subscribe Does a sprinkled tenant space Group M with an occupant load of 51 and sprinklers separated by fire-rated walls from the rest of the mall need automatic fire detection?
I think a pull station or the flow switch to active the notification would be enough. The existing plans show detection in the main sales area, in the electrical room and where the power supply for the NAC is located. According to my analysis the only mandatory detector should be the one in the power supply room. Wouldn't you agree? Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe Are stand-alone clean agent systems required to be monitored by a supervising station or constantly attended location?
I am reviewing plans for a small, remote equipment shed that is equipped with a clean agent suppression system. The building is remote enough and small enough that IBC wouldn't require a fire alarm or sprinkler system. The designer claims that it doesn't have to report out, but I think they're wrong. I think this would fall under the IBC 907.3 requirements for a dedicated function panel, which still requires supervision of the detectors at a "constantly attended location." Since the building isn't constantly attended, it would have to dial out to the central receiving station, not just to some guy's email. From what I've gathered, a full-blown FACP wouldn't be required, but a dedicated panel to dial out would be. What is your take on this? Thanks in advance. Sent in anonymously for discussion.

Could you use one detector to activate both recall and door closing, so long as you comply with the spacing requirements for both the doors (based on ceilings) and distance to the elevator(s)? I don't see why you couldn't if you have an intelligent system that could achieve this through programming, and I don't see anything in NFPA 72 that would prohibit this either.

The last tenant was a large pharmacy chain that monitored their own fire alarm or sprinkler systems. When they left they removed the alarm panel.
The tamper and flow switches are still there, as well as an exterior electronic flow bell. Does this sprinkler system require electronic monitoring? Currently they have nothing monitored. I would like it to be monitored, but need something to back me up. We adopted the 2021 I-Codes and 2015 NFPA 101 (Statewide). Thanks in advance. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe Hi, I am a Fire Alarm system installer and have been active for 25 years.
I am writing today because the change from the UBC to the IBC, or some other change that I am unaware of, has removed the requirements to do anything in an existing un sprinklered building in Washington state. Looking at the requirements for E occupancy, specifically for a sprinklered building, it says to install heat detectors in most locations. There is no guidance for what to do in an existing non-sprinklered building. This has led some to remove smoke detectors from projects and install only heat detectors other than the one for the panel and power supplies, treating sprinklered buildings and non-sprinklered buildings the same. I am alarmed by this and think it’s a mistake we will regret. On a sprinklered building, you have suppression, so the fire will likely be in a controllable state when first responders arrive. It makes sense that early warning would be redundant, other than areas like exit pathways or sleeping areas where someone could be overcome with smoke or the exit path may be blocked. Early warning devices are necessary in those cases. If we get the people out safely, then the firemen don’t need to go in. Early warning devices achieve that. But on a non-sprinklered building there is no suppression. Heat detectors do not go into alarm until the fire reaches them, they are mounted on the ceiling so the walls and building will be on fire before they activate. Smoke detectors will go off when the fire is smoldering getting the first responders on the way before the building is on fire. Oh, and getting the people out of the building before it’s on fire, one of my personal favorites. My goals, 1. I wanted to add some beam smoke detectors over the gym floor area and some smoke detectors over the stage due to the large amounts of fabric. 2. I intended on replacing all the devices on the permitted installation with like for like. Resulting in smoke detectors in the areas that currently have smoke detectors. Both of my submittals (to the architect) showing smoke detectors were rejected and I was instructed to show heat detectors. I have no way to argue for the smoke detectors, there is no guidance I can find. We are removing all the life safety out of the life safety systems. Is there something I am missing, is there a way I can fight to get smoke detection in the halls and classrooms that do not have an exit doors? I looked at the 2021 IFC chapter 11, specifically 1103. I hoped I had found my solution but reading it more carefully, I see the intent of that statement is the table. I can’t find anything on that table that will keep the early warming detection in the life safety system. I know the goal is to reduce false alarms. Smoke detectors have a bad reputation for unwanted alarms. On this project they were suffering from false alarms. That is the reason they are wanting to eliminate smoke detectors. With in a half hour of being on site the existing system went into alarm. I viewed the point, found out it was a 135 fixed temp heat installed in an attic that was at 150. So Heat detectors false alarm as well when incorrectly applied to the environment or poorly maintained. Are we going to regret this or am i just an old man with old ways of doing things?

Click Title to View | Submit Your Question | Subscribe We were looking to tie multiple fire alarm systems together from various vendors such as Honeywell, Siemens, Notifier, intermesh, etc. The end goal is to bring all the zone data for a building to a Siemens Desigo Fire Server.
Currently, the Monitoring-Only Solution Assembly (MOSA) ring will not accommodate the Honeywell, Notifier, or other non-Siemens panels to bring in a complete data stream in. We are limited to the standard supervisory signals for trouble, alarm, duct detectors, pull station, and smoke detectors as a limited set of data. Does anyone have an interface that would bring multiple data points from other vendors' fire alarm panels to the Desigo front-end? Siemens and Honeywell do not support each other’s components. The MOSA ring is a Siemens product. A 3rd party would be required to facilitate the interface panel. Sent in anonymously for discussion.

They wish to install a static airplane fuselage for training airplane cabin personnel. This would be a functioning fuselage with standard airplane doors with ramps.
