Fire Alarm Drawings and Blueprints

This is a topic where you can post pictures of fire alarm drawings and blueprints!

You start! :smiley:

lmao, I think only a few people here could do that. I’m not even sure they could even do it anyways depending on what it is you are looking for. Some stuff like that could be sensitive information.

Okay here is a aimplex 2099-9754 t bar pull station.

Here’s a bunch of drawings:

I agree with you and I do not think this topic is going to go very far.

Here is the schematic for the Quick Alert 2400 (Homemade) FACP. I am currently developing the 2450 (has supervision).

Ok, ready for a good laugh… Here is a small daycare I designed a long long time ago. One of the first systems I had to design by myself with very little design training or experience. Yes, this is a very crude drawing but it worked! The company I worked for at the time this is how they did their drawings. No software, no computer - just pencil, drafting paper, and a stencil. Fire marshal approved it, system got installed and certified, and as far as I know, still in operation today. The panel was a Napco 6024 conventional zoned system. Installed in a house converted into a commercial daycare. I did remove all the confidential information from the prints such as the job name, address, license number, etc. I also tried to resize the images down small enough without loosing too much detail - but if they are too big and an admin wants to remove them that’s understandable. I do have another set I can post if these look fine.

You didn’t put zone ID’s on any of the devices?

Looks like a decent FA drawing to me, for what it is. :smiley:

Out of curiosity, what were the pull stations and notification appliances?

Yeah, I noticed that too! Not sure how that got through the FM office. I think things were a bit more relaxed back then.

I know the smoke detectors were System Sensor 2100 series. Pull stations were either the Edwards 270’s or Firelite BG-10’s when they were just about disappearing, I don’t remember. System Sensor Spectralert (old style) for the horn/strobes and System Sensor PA400R sounders. FACP was definitely a Napco 6024 with the old PROM chip and programmer.

Funny too because I look at that print and see how much I can improve the system. There are only two horn/strobes on the first floor and no strobes near any of the “classrooms” - just those little sounder units. Probably wouldn’t hurt to add a smoke detector in the office. But that’s what the boss wanted to put in and had to go with it!

Yea, I noticed no strobes in the restrooms and I assume some of them are public use and those sounders would have to be horn strobes nowadays.

It’s amazing how much notification is required today though when you look at what’s in older systems. We replaced a system in a school built in the early 90’s that had a single horn strobe per corridor (some well over 100’), right in the center. One in the gym, one in the lunchroom, a few in the library… :lol: I think we more than quadrupled the devices when it was all said and done.

That happened to my elementary school, which was built in 1990. Original alarms were Simplex 2901-9838 horn/strobes on 4903-9101 strobe plates. There was one in the cafeteria, one in the gym, one in the library, and some more scattered around the hallways In 2005, they completely upgraded the system (Simplex 4100U with addressable TrueAlert’s as the NA’s). Now, there are (about) three alarms in the cafeteria, four in the gym, four in the library, even more in the hallways, and one in each classroom. That makes me wonder if the school will get another upgrade in 2020, and if so, what new changes that will bring.

Before they upgraded the system, I remember my class missing a fire drill because everybody was talking/being loud and we couldn’t hear the horn out in the hallway, so it’s probably good that the code requirements changed. :lol:

Speakers and amber strobes for mass notification. :smiley:

Is that at all required or regulated by code yet? That would be good to have in schools though. Just a few months ago, actually, there was a lock down drill during my band class that we completely missed because we couldn’t hear the one quiet intercom speaker in the room over everyone playing.

Doesn’t signalling code mention it should be louder than average room noise ?

In Delaware the code applies to when the building was built, or if there was a major renovation. If the building was built in 1940, whatever the fire code was in 1940 is what the building owner is required to follow. If the owner does a major renovation on the building, meaning stripping down to the studs or changing the layout or occupancy, then they have to update to current life safety codes. If they only update a small section, normally nothing is required. They have tried unsuccessfully to force building owners to update systems to current codes, most noticeably are the fire codes in the city of Wilmington. After a highrise fire where there was a loss of life in an unsprinklered building, they wanted to force the owners of the three remaining unsprinklered highrises to install sprinkler systems. Never went through. About the only thing they were able to do was about 20 years ago require all residential multifamily buildings (apartments or condos) to install a fire alarm for residential corridors and common areas - nothing required in the tenant spaces except single station smoke detection. Even if a building like a school has an existing fire alarm from the 1960’s and the fire alarm panel gets fried, you only have to replace the panel. Don’t have to touch any for the field devices except replacing end of line resistors.

Best example of this craziness is the Christiana Mall in Newark right off I-95. You will walk into a store that has been there for years and there are absolutely no fire alarm devices within the store - no horns, pulls, smokes, duct detectors, anything. The music would be blaring and the place on fire and nobody in that store will know. Right next door, a recently renovated store will have speaker/strobes, smoke detection, waterflow switch on the sprinkler line feeding the store, audible shut down, the works!

If I remember correctly, I think we didn’t have to put strobes in the bathrooms because they were not ADA compliant rooms to begin with. This was a house that was converted into a daycare, I don’t even think today they could get away with that without renovating the building to ADA standards. Plus they would have to retrofit in a sprinkler system, something this building lacked.
