I also have a second system to share. My high school (Where i still currently go) has a more typical system installed. Hawthorne High School in Hawthorne, NJ
The notification appliances are Wheelock 7002T's set to continuous. They are installed throughout the hallways and other certain rooms. No classrooms have any N/A's other than the music room, for obvious reasons.
There are two student restrooms at my school. One f them has a Wheelock RSS strobe,the other one has a Wheelock WH3T-24-FR strobe in it.
For pull stations, there are Simplex 2099-9768 chevrons. Many have been replaced with either Simplex 4251-20's or 4099-9001 t-bars. The boiler room has a silver Edwards 270-SPO for some reason though.
For detectors, System Sensor 2424 smoke detectors are found in the hallways and in certain rooms.
Black Chemtronics fixed temperature heat detectors are found in the classrooms. Some have been replaced with newer white Chemtronics rative rise heat detectors probably re branded by System Sensor.
I'm not sure of what the original control panel could of been. I've haven't found an annunciator or any other clues. It's probably been replaced with a Fire Lite MS-9200UDLS or some other Fire Lite panel.
Seems to be a pattern in the Hawthorne public school district, a Fire Lite system with Simplex pull stations. Maybe they originally had a contract with Simplex, but then switched to Fire Lite when Simplex got too expensive for them.
