Yep, though I think at these schools, some students may break the glass for fun even if they don't pull the alarm. I know at one of the schools I've seen them in, roughly half of them have replacement glass in them.
They probably installed it that way due to the trophy case that was probably there before the Simplex 2001 system was installed.

I have a few questions to ask you safetech 1 how long does it take to test a fire alarm system. 2 if you were testing the system and a fire happens at the same time what happens the alarm will sound but people know it a test and not the real thing 3 I may asked this before but why do u do walk test why can't you leave the system in normal mode while testing I want to hear the signals whole time Durning testing and 4 what the loudest system you ever ever heard and the last question has the alarm ever scare you when testing ?
Hi Stephen thanks for your comment. 1. The length of time varies depending on the size of the building, number of devices, issues encountered while testing, ect. Inspections can little as a couple hours ranging to days and weeks at a time. 2. Believe it or not this has happened to me before. Luckily it was during a lunch break and it didn’t cause much interference. While working on a system, I usually have a way of knowing if an alarm is received in an area I’m not testing. If this occurs, I would investigate to see if it was a legitimate alarm. 3. Walk-test has multiple benefits. It allows single person testing with minimal disturbance. Many people become distraught if I let the audibles sound the entire time. Therefore I try to limit that as much as I can. There are times however where the setting requires me to do this. Just not every time. 4. Most all fire alarm systems are loud. I have fooled with many different types I would consider noisy and some not noisy enough. Having seen and heard so many I’m unable to give you a direct answer to this. 5. For your last question the answer is no not really. Mabye on a couple of rare occasions however referring back to my last answer I have worked on these systems for quite awhile to the point where it doesn’t bother me much.
Nice Oldie. Is the 4100U the original panel? Some of those older Horns/Lights seem that they wouldnt have been the 4100U's era. I thought the horizontal rectangular Hornstrobes (The ones that came before truealert line) were 4100U era
+JMAN123436 Definitely not the original panel. Most of the devices sound like Simplex 4051's. There was most likely a 2001 panel or something similar here. Some devices are newer though, like that 2099 or 4099 pull station and the TrueAlerts.
+msj191961 It looks like the school was built way back in the middle of the last century (maybe up to the '50s.) Then the 4051+4050-80s were installed during a fire alarm upgrade in the '70s on a Simplex 4207, 4208 or even a 2001 system.
2001 was the original panel to this system which later upgraded to a 4100 with the addition of a wing where you briefly heard the 9840's towards the end of this vid. A 3rd addition was renovated when at that time the U panel came along

The older panel most likely failed an inspection and was replaced with all the original equipment left installed, no sense replacing everything if it's just the panel that failed.
I've seen many examples of that. At my friend's university, the art center had those same old Simplex 4051+4050-80 horn/lights from the 1970s, but the panel was a Simplex 4002 from the late 1980s or early 1990s, next to an abandoned and gutted 4208 cabinet (the old 4208 probably failed, so they replaced it with the 4002, but kept all the old stuff intact, in addition to installing some new smoke detectors.)
And now the 4051 horns at that art center are gone; they slapped TrueAlert horn/strobes onto the 4050-80 light plates when they replaced the 4002 panel with a Simplex 4007ES a few years back. But they kept the existing 4251-30 break-glass pulls and 2098-9201 smoke detectors.
It is likely that the panel was upgraded for a certain reason and it is cost effective to leave the older horns grandfathered into the system than to upgrade them. In this reason, the panel got upgraded due to the building having an expansion, which is one of the common reasons older systems get their panel upgraded. Likely the 4100U was installed and the expansion areas got new devices while the older areas had their devices grandfathered.
They are very loud on continuous but the 4051s are louder. By the way they technically aren't TrueAlerts, they're QuickAlerts because notice no TrueAlert marking and different strobe reflector takes place.
I recall many 1970s Simplex fire alarm systems were set on Continuous, at least the horns were, while the visual signals (if any) would flash on and off (typically via the panel's coding wheel.)
No, that's still a Simplex 4050-80. But the school I went to for kindergarten DID have a 4051+AV32 combination in the small gym, as well as one in the main gym. In both cases, the AV32 plates were replacing 4050-80s that were damaged by balls or something.
I have more questions to ask 1 I notice there a fire alarm system in my formor school and I noticed when the alarms sound all the horn strobes dinit come on instantly for exmaple the alarm would sound in the gym first for 5 seconds then cafe horn would start then hallway alarms would start then classrooms why did it do that pattern idk but it lasted 5 seconds before more horns started so it took 20 seconds for the whole system to start up why did it do that was the system set up to do that or what 2 how loud are spealert advances and how loud are ibm horns and truealetts
