Here’s one based on Disney’s Recess:
Third St Elementary School, built in 1928, originally had a pull-rod fire alarm system, which was automated in 1955 with a Standard Electric Time UAX-3 Fire Alarm System. The alarms were Standard Electric Time rebranded IBM 4030-2 Horns, installed mostly in the hallways, the library, and cafeteria. The auditorium and gym had Standard Electric Time rebranded IBM 4030-1 horns. The pull stations were mostly Standard Electric Time 200117s and Standard Electric Time heat sensors were installed in many areas. Signal coding was 17-0-0. The school bells were mostly Standard Electric Time 6 Inch Bells, mostly in the hallways, larger classrooms, and the library. Outside, and in the gym, cafeteria, and auditorium, they had Standard Electric Time 10 Inch Bells. Most if not all the classrooms had Dixie Buzzers as well. The master clock system was by Standard Electric Time AR2A with bell circuits.
In 1972, a lightning storm took out the fire alarm panel, and unfortunately, the entire fire alarm system went down with it. The basically took out the old system and put in a new Standard Electric Time SET7000 Fire Alarm System. The new signals are Standard Electric Time 4-350 Horns on Light Plates, and even some installed in larger classrooms, the band room, and art studio. The pull stations are Standard Electric Time 200117s and Standard Electric Time heat sensors were installed in many areas. They also installed a few Statitrol Smoke Detectors as well. Signal coding was continuous.
In 1977, a 6 Inch Bell died. It was replaced with an Edwards 6 Inch Bell.
In 1979, a 4-350 Horn on the second floor died. That was replaced with a Federal Signal 450 Horn.
In 1981, two 200117s broke. They were replaced with Edwards 270-SPOs. Also a 4-350 and it’s light plate was found inoperative. It was replaced with a Space Age Electronics 2DCD Horn on a AV32 Light Plate.
In 1985, a Senitrol smoke detector malfunctioned. It was replaced with an ESL Smoke Detector. Also a 10 inch bell was found to be inoperative. It was replaced with a Faraday 10 Inch Bell.
In 1989, a 200117 was found inoperative. It was replaced with a Fire Lite BG-6. A heat detector was also found inoperative and was replaced with an Edwards Heat Detector.
In 1991, a 4-350 in the library died. It was replaced with a FOS 6120-5511 Horn/Strobe, the light plate was also disconnected. Around the same year, a light had malfunctioned and was replaced with a Wheelock RSS Strobe.
In 1994, the SET/7000 malfunctioned. The panel was replaced with a Notifier AM-2020. Everything else remained the same. Also, an elevator was put in, and System Sensor 2400 Smoke Detectors were installed for elevator recall purposes, these were tied into a Pyrotronics System 3, which was tied into the AM-2020. Signal coding is continuous.
In 1995, two 4-350s (one in the 3rd grade wing, and one in the locker room), along with a light plate were found inoperative. The 4-350s were replaced with Gentex GMS Horn/Strobes, and the light was replaced with a Gentex GXS strobe. Also a Notifier BG-10 was installed to replace a broken 200117.
In 1996, the school gained fire sprinklers, and a Federal Signal 350+iStrobe were added as the sprinkler alarm.
In 1997, the school’s clock system was broken by a student throwing a ball at the playground clock. The system was replaced with a SAL 3000, replacing the internal bells and the intercom system. The bell was a tone over the intercom. The external bells were initially disconnected.
After a few months, the system began malfunctioning before becoming inoperative altogether. The original playground clock was re-installed. The internal hallway bells and dixie buzzers were removed, and the PA System was replaced with a new Bogen Multicom 2000 system. New Bogen Clocks and Speakers were placed around campus, and new call in switches were installed in the classrooms. The internal bell is a 4-second tone over the intercom, and the external bells were connected to the new master-clock system, which is a Lathem System.
In 1998, a 4-350 was found inoperative. It was replaced with a Wheelock MT-WM horn/strobe.
In 2002, a pull station in the auditorium was found inoperative during a fire drill. It was replaced with a Notifier BG-10. Also, System Sensor remote strobes were installed in 3 restrooms.
In 2004, the auditorium and gym were renovated. The main FACP was replaced with a Notifier NFS-3030 with DVC. The alarms and pull stations in those areas were removed. The new alarms in the gym and auditorium are System Sensor Spectralert Speaker/Strobes, with a few remote strobes where coverage was needed. The new pull stations are Notifier BG-12s and Notifier FSP smokes were installed as well. The speaker strobes play a slow whoop tone and voice evac message. Everything else remained the same.
In 2005, they installed System Sensor Spectralert Horn/Strobes in 2 classrooms because teachers began complaining that they couldn’t hear the fire alarms. Also, a 200117 was replaced with a BG-12LX.
In 2006, a 4-350 in the kitchen died. It and the light plate was replaced with a Mircom Select-a-Horn/Strobe. Also, a Heat detector was replaced with an System Sensor Heat Detector.
In 2009, a 4-350 in the 5th grade hallway was replaced with a System Sensor P2R.
In 2011, the Kindergarten and First Grade wings were renovated, along with the art room, which was in that wing. The 4-350s in that wing were replaced with Wheelock MT-24VFR Horn/Strobes, which were also installed in the classrooms, 2 of which were converted to computer labs, and Wheelock RSS strobes in the restrooms. The 200117s were replaced with Notifier BG-12LXs and the heat and smoke sensors were replaced as well. A Wheelock ASWP horn/strobe was installed outside. The 2 Standard Electric Time 10 Inch Bells were replaced with Wheelock MB10s. Also, a 200117 broke and was replaced with a Notifier BG-12LX.
In 2014, 5 classrooms were renovated. Those classrooms gained a Wheelock MT-24VFR Horn/Strobe.
In 2015, a smoke detector malfunctioned, and was replaced with a System Sensor i3.
