Fire Alarms in Buildings (2.0)

Some type Siemens system. First Ascend series devices I’ve seen.

Cool! Based off of the annunciator, this is likely a Siemens Desigo FC2005 50-point panel.

In this case, the compartmentation must consist of 2-hour construction, including fire doors at the entrance to every classroom. I would be surprised if that was present.

The voice evac requirement in Group E applies when the occupant load is above 100. Given that there are around 100 students and the building is also occupied by 13 teachers, other administrative staff, and potentially visitors, the total occupant load is probably over 100.

Fitting name since there are ceiling-mount devices on the wall.

Surprisingly, I did see that the classroom doors were fire rated. I didn’t see the length.

There’s a good chance the construction is only 1-hour rated if it is at all, since that is the IBC requirement for corridors in Group E without sprinklers, and I found a similar requirement in the 1966 and 1976 editions of NFPA 101 (though there was no sprinkler exception back then). I don’t know what code was used by that particular area back then.

Might be on life support, but yeah it could

Ritchie Hall- Bismarck State College- Bismarck, ND

This is a dorm building with a few suites, and a few common areas as well. Each suite has two bedrooms, a bathroom, a kitchen, and a living room.

Fire alarm system:

Panel: Siemens Cerberus PRO FC922 (or other size Compact panel)

Notification Appliances: The common areas have Siemens ZH-MC-R horn/strobes. Each suite also has a ZH-MC-R in the hallway outside of the bedrooms.

Pull Stations: Siemens HMS-S pull stations throughout the building

Detectors: Siemens OP921 smoke detectors in the common areas

Smoke/CO Alarms: Each suite has its own system of interconnected First Alert smoke and/or CO alarms.

Other Notes:

  • This is a fully sprinklered building
  • This building was built around 2016
  • There is a sister building directly adjacent to this one. It is pretty much a mirror image, and has exactly the same system.
  • This college campus has almost an even split between Siemens and Simplex systems. The only system that isn’t from one of those two brands is in the medical building, which is partly owned by another company, and has a Bosch system with Wheelock Exceders.

Something ironic:

This building is located on Edwards Avenue. Funnily enough, I’m not aware of any Edwards systems at all in that area, and Edwards Ave. is possibly one of the furthest places you can get from an Edwards system in the city. Every building on Edwards Avenue has either a Siemens or Simplex system. This interesting irony is the main reason why I posted about this building, as it’s otherwise pretty basic and boring.
