I shadowed a an elementary music teacher (school not disclosed for privacy reasons) yesterday for an over-break assignment. I had been in the school before, but it has been YEARS and there have been some renovations and additions to the original buildings (1976) since then. I knew the system was Simplex, but here’s the full rundown.
The original school opened in 1921. The only remaining part from the original is a 1963 classroom wing addition (now houses grades 4-5 , special ed and “specials”–music, art, etc). The rest of the school was rebuilt and opened in 1976. 1976 classroom wings (K-3) were originally the open-pod type; only Kindergarten still has a fully open pod. The other pods now have folding wall dividers added (probably) in the 1990s. The walkways between the buildings were enclosed into hallways in 2016 and fire doors replaced the existing exit doors.
Control Panel—Simplex 4005–Main Office, replacing the 1976-installed 4207 or 4208. Installed June 1997! Simplex wrote the date on the framed operating instructions sheet next to it.
No remote annunciators.
Initiating Devices
Simplex 4251-20 pull stations—1976 (flush mount) and 1963 buildings (surface mount).
Simplex/Chemtronics heat detectors—1976 and 1963 buildings—not many of them.
Simplex 2099-9754 pull stations—2016 additions/enclosures. Mainly by the new exits in the enclosures/additions.
Simplex 4098-9601+4098-9683 smoke sensors—2016 additions/enclosures—mainly near fire doors.
Notification Appliances
Simplex 4051 horns—1976 classroom pods, hallways, offices and main lobby (flush mount) and 1963 buildings (surface mount).
Simplex 4051+4050-85 horn/lights—cafeteria and multi-purpose room (gym/auditorium).
Simplex 4901-Series rectangular horns on 4904-9104 ceiling strobe plates (ceiling mount -9105 strobes)—1976 classroom pods with folding walls. Probably installed with the 4005.
Simplex 4903-9252 15 candela horn/strobes—2016 enclosures/additions. The enclosures I went through only have 1 horn/strobe in them.
No remote strobes to be seen, but that doesn’t mean there aren’t any.
No exterior alarms visible.
Coding is probably continuous or temporal; I haven’t heard the system in alarm.
Clock system is a Simplex 6400. Clocks are your standard, round Simplex fare. Not sure what the PA system is, but classrooms have Bogen wall speakers. Hallways have 8" round speakers with no external branding.
