AHJ's Ideal FACP Location and FAAP Mandate?

12/9/2025

From a designer's perspective, if a building is small and simple enough, and the owner doesn't care all too much about finishes, then locating a main fire alarm control panel and auxiliary equipment (like a transceiver) can often go near the front entry of a building.

In almost all other cases, I would prefer a back of house space.

From an AHJ's perspective - what do you prefer to see for the main fire alarm control panel location?

If the panel is anywhere but the front main entry, do you always mandate a fire alarm annunciator panel?

NFPA 72 (2025 Edition) states that "All required annunciation means shall be located as required by the authority having jurisdiction to facilitate an efficient response to the situation." Is that your go-to reference to make sure that either the main panel or an annunciator is at the front entry?

I understand the design side, but I'm interested in your thought process in terms of plan review and operationally what you would expect to see across a variety of projects.

Thanks in advance.

Not an AHJ.... but it's generally appreciated near the sprinkler riser.

Easier to wire. Easier to test.

Really depends on the building....a strip mall or other multi-tenant planned space spread out with multiple entrances, riser room is better. Buildings like a doctor/dentist office (single tenant) or a multi-tenant with one main entry, right by the entry door is better.

Several of my local AHJ's require it (amended IFC) in a location visible form the lobby or an adjacent room visible and accessible from the lobby, with signage of course.

I was an AHJ several years ago. I always prefered the riser room, and in the case of larger buildings; an annunicator in or near the main entry / lobby area.

Remote annunciator, or the panel itself needs to be visible from the primary entry point.

As an AHJ, I want my incoming companies to be able to find the annunciator quickly (fast and efficient) and confirm the signal that was transmitted from the Central Station and able to silence or reset the moment they walk in the front door.

It seems like some guys get hung up on the panel itself being readily locatable…. I feel like that’s some kind of old hat thing. Some guys want a remote annunciator in every unit of a strip mall… I can see the benefits of this, but it can get quite costly and if it’s a very big strip mall, it might make you step yourself up into a higher end panel to accommodate that number of annunciators.

High-rises need the panel in the FCC. But they need a remote annunciator at the primary entry point.. The term primary entry point is quite subjective and that requires you to check with the AHA every time…. There are many situation where it’s obvious when there’s only One or clearly primary Door.

In summary, there is no one good answer and having a good working relationship with the AHJ is critical.

As a current AHJ, I prefer an annunciator panel at front door on medium to large projects. The FACP can be in the back preferably with the sprinkler riser with signage on exterior of door stating FACP inside.

It depends on the type of building and the expected users. I like the idea of the riser room if it is easily locatable and accessible. I also like the idea of placing it in the main entry if there are limited accessories required to be provided with the panel.

Besides the section in NFPA72, IFC 907.6.4.1 states that a zoning indicator panel shall be provide in an approved location. That gives me as the AHJ the ability to select an appropriate location for the project. Generally, we require a remote annunciator at the main entrance if the FACU is in another location.

As an AHJ, we do not want our firefighters to enter deep into a building to find the alarm panel, when they may get trapped by a hidden fire. We want the main alarm panel in a secure location (riser room is fine), but always have an annunciator near a main entrance. In a strip center, one annunciator is often fine, we just denote the location on our preplans.

Out of curiosity (I'm not a firefighter), how often do you use/reference preplans, and how familiar are you with any one of them?

It is a "I know where all the panels are for all the buildings in my station's area" level of familiarity, or a "I'll glance at a binder in the truck on the way" level of familiarity?

Sincerely asking, not mocking or accusing or anything.

I am an AHJ and former Shift Commander for my department. We now have pre-plans electronically accessible on tablets in all apparatus and when we get dispatched the CAD mapping shows up with an icon to click to open the pre-plan (if it is completed). We used to have the binders which we hardly ever used. We are a relatively small community of approximately 28,000, but still have too many occupancies to have them all memorized as to panel locations or even which buildings have alarm systems.

Not a firefighter but Boston Fires FPE so office is next to FF. They say they never look at plans. Its just preplanning and training on buildings.

Wherever it's going. Make sure you get it in writing on the approved prints. The date, note and printed name with signature. I've had a jurisdiction change the location 3 times (yup 3 different inspectors - no consistency) all done after the walls were painted. My supervisor at that time refused to get the signatures and we moved the panel each time. Delayed the opening a week.

From the viewpoint of an AHJ with 18 years in fire operations, crews strongly prefer the main FACU located right where first responders enter the building—at the primary entrance, main lobby, or fire command center. It must be in a secure, climate-controlled space that's easy to access without searching.

Full-function remote annunciators (or graphic annunciators, GAPs) are highly recommended for larger or more complex projects at the firefighter entry point. This lets crews acknowledge, silence, or reset alarms without walking to the main panel. For small, simple systems where the FACU is already front-and-center, they're often not mandated, as they add little value.

In practice, place the FACU in a dedicated spot at the main fire department entrance. Add a graphic or full-function annunciator in the lobby for mid-size or complex buildings. For small single-story projects, the FACU alone at that entrance usually suffices if it aligns with codes and local rules.

One other bit of advice: Be cautious when proposing GAPs—consider the project type carefully. Avoid them in occupancies prone to frequent tenant improvements (TIs), as they drive up costs on new installs and become a major hassle during modifications for new devices.

From an AHJ point of view, the Building Code (in Ontario OBC 3.2.4.8) states that an annunciator shall be installed in close proximity to a building entrance that faces a street or an access route for fire department. The reasoning for this is that if an alarm was to go off, the fire department on arrival can see exactly what zone was triggered, as the annunciator is at the main entrance.
