The school may have been built in the 60s or early 70s and probably had an older Simplex system. Do the Chevron pulls look like THIS? Then they’d actually be 4251-1 Cheveon pulls; 2099-9768 is the model number for the later version from the late 80s and the 90s. Then the 7002Ts were probably installed during a fire alarm upgrade in the 80s or early 90s. I remember an elementary school in a neighboring town having that setup, along with disconnected 4030 horns next to the 7002Ts, but your school probably completely removed the old Simplex alarms.
Anyways, I am going back to my old college next week for a computer course, as I am now going for a computer science degree. The only building that has had any real changes with their fire alarm system is the Student Center. Here is what they currently have:
The panel is a Notifier AFP-200, located in an electrical room on the ground floor, next to an abandoned Standard panel (the original system form when the building was built in 1971.) There’s an LCD-80 annunciator at a ground floor entrance, next to what appears to be the original four-zone Standard annunciator.
Two sections of the ground floor (where class registration offices, computer labs and such are located) were completely renovated in 2013-2016. The alarms in these renovated sections are just System Sensor SpectrAlert Advance horn/strobes (probably P2Rs.) In the ground floor corridor and the library, there are the original Standard 450 horns, on the silver flush-mount light plates that had been modified with a 90s-style ADA Faraday strobe replacing the original light. The student lounge, the kitchen and cafeteria have Faraday U-HN horn/strobes, but also in the cafeteria is a Simplex 2903+2901-9833 horn/light (obviously replacing a Standard horn/light some time in the 1980s.) I believe coding for the non-renovated areas is Continuous.
The renovated areas of the building have Notifier NBG-12LX pull stations; one of them has a Stopper II cover. They blink red, due to them being hooked up to a non-ONXY addressable Notifier panel (in this case, the AFP-200.) Non-renovated areas generally have Faraday F1G Chevron pulls on Space Age/Faraday ADA-extension adapters, and in the kitchen and one end of the library, there are Fire-Lite BG-12 pulls (replacing the last two original Standard 200177 pulls early this year.)
In the renovated areas and at the elevator, there are Notifier FSP-851 smoke detectors. At the elevator they are on the older-style System Sensor base, but in the renovated areas they are on the newer conical base. Everywhere else uses heat sensors; mostly old Chemtronics 500-series mechanical heats rebranded by Standard, but in the kitchen there are Chemtronics 400-series heat sensors, and there is also a Simplex 4255-5 heat sensor (rebranded Edwards heat) in the library. A few of the old Standard/Chemtronics heat sensors were replaced with new Chemtronics 601 heat sensors.
My class this semester is in the Technology building. It and the adjacent Science building share a Notifier NFS2-640 system rebranded by Johnson Controls, with Wheelock Exceder horn/strobes (many of them on large red trim plates, covering up where old Standard horn/lights and then Space Age VA4 horn/strobes were), NBG-12LX pulls on Space Age ADA-extension adapters, and addressable Notifier/Johnson Controls smoke detectors (they look like SD-651s). Also in the Technology building is a gutted Faraday FireWatch II panel that’s now just used for terminal wiring, left over from the previous system.
The Business building has a similar setup, but with an NFS-320 panel rebranded by Johnson Controls. IIRC, they are all on Code-3.
The Liberal Arts and Humanities buildings share a Faraday MPC-7000 system, with Space Age VA4 horn/strobes, addressable dual-action Faraday Chevron pulls, and FireSmart smoke/heat detectors. This is the only non-Honeywell system on the campus, I think, and is up for replacement soon (probably with another Notifier system.) These two buildings were originally built in 1978 with Simplex 4207 systems with 4051+4050-80 horn/lights and 4251-20 T-bar pulls.
The Fine Arts building also has a Notifier NFS2-640 system, with the panel located in an electrical room. The panel has an NCA-2 annunciator incorporated into it. At the main lobby, there is an FDU-80 LCD annunciator, replacing the original Simplex 4308 annunciator from when the building was built in 1978.
All the alarms are SpectrAlert Advance horn/strobes on adapter plates (probably P4Rs), replacing Space Age VA4 horn/strobes and Simplex 4051+4050-80 horn/lights (with the latter, it’s just like what happened at my old school!) In the background/prop storage room in the basement, the SpectrAlert Advance in there is not on a trim plate, but mounted by itself on the wall, as the previous alarm in there was mounted on a backbox.
Most of the pull stations are the original Simplex 4251-20 T-bars, but in the auditorium, there’s a Faraday F1G Chevron as well. The majority of the pulls have Stopper II covers over them (some with sounders and some without), except in the TV studio and in a small room between the Little Theater and one of the corridors. (The pulls in the auditorium and on the stage had Stoppers installed on them early this year.) Smoke detectors are mostly System Sensor 2151Ts, along with a few 2451THs and i3s, and the elevator machine room in the basement (for raising and lowering a portion of the stage so it can be used as an orchestra pit) has one of the original ESL 523C smoke detectors intact. Also in the basement there are some of the old Simplex 4255-1 heat sensors (rebranded Chemtronics 500), and the TV studio has a couple of Simplex 4265 heat sensors (rebranded Chemtronics 400.)
The Administration building has a similar setup as above, but none of the original smoke detectors are intact, and all the pulls are Simplex 4251-20s; all but two have Stopper II covers. The building also has a Potter fire suppression system in the computer server room, with newer-style Potter Select-a-horn/strobes (and a SpectrAlert Advance as well.)
The Field House building has a Fire-Lite MS-9600UDLS system, with the main panel located in the main lobby, linked up to a junction box where the old Faraday RDC-700 annunciator was. In an electrical room, there’s a gutted Faraday MPC-2000 panel that has a Fire-Lite power supply cabinet plastered to its’ front. All alarms are, again, SpectrAlert Advance horn/strobes on adapter plates, and the pulls are mostly Simplex 4251-20 T-bars, while the swimming pool room and the girls’ locker room (I saw through an open door) have Faraday F1G Chevron pulls. The pulls in the gymnasium, swimming pool room, and a couple of short hallways have Stopper II covers without sounders. The only smoke detectors are one above the panel in the main lobby and in that electrical room, which are Fire-Lite SD-355T detectors. Everywhere else uses heat sensors, mostly Simplex 4255-1s (though the boys’ locker room has a Chemtronics 600 detector as well.)
