This system is based off the school featured in Bruce Coville’s book “My Teacher Fried My Brains.”
The Kennituck Falls Junior High School, built in 1978, has a Simplex 4207 fire alarm system; the panel being located in the main office, and one of those old large two-bay Simplex annunciators (with the indicator lamps having zone locations written on them) located outside the office.
The alarm signals are red 10-inch vibrating Simplex bells. To avoid any confusion with the school bells (which were 6-inch beige Simplex and blue Edwards Adapt-a-bels installed next to each alarm bell), the fire bells were flush-mounted behind gray grilles (the school bells were surface-mounted on trim plates), with remote 4050-80 lights underneath the grilles (with black “FIRE” lettering), The bells would ring in Continuous while the lights flash in slow March Time.
All the pull stations were Simplex 4251-20 T-bars, rigged so that when one is pulled, purple ink winds up on the puller’s hand. Old Simplex 42XX-series wiffle-ball smoke detectors were also installed in the hallways, stairwells and in large rooms. Other areas had 4255-1 mechanical “bell-shaped” heat detectors installed.
They also installed a Simplex 4051 horn on a Space Age AV32 light plate outside the building, not too far from the main entrance. Also next to each exterior school bell (6-inch Simplex bells flush-mounted behind grilles), a beige Simplex 4050 horn was installed for use as an all-clear signal at the end of fire drills, and for other non-fire emergency purposes.
In 1988, a few of the older detectors were replaced with photoelectric 2098-9636 “wiffle-ball” heads on 4-wire 2098-9536 bases. Additionally, at least two of the Simplex fire bells were found to be no longer working, so they replaced them with Simplex 2901-9838 horns installed behind the grilles.
A modular building was then added in 1998, and a Simplex 4004 fire alarm panel installed next to the 4207, also providing system monitoring. The modular building had Simplex 4903-9236 horn/strobes, 2099-9756 dual-action pulls and 2098-9201 photoelectric smoke detectors.
During 2003-2008, roughly half of the old ion smoke detectors wore out and were replaced with 4098-9601 photoelectric TrueAlarm detectors. Another Simplex fire bell also malfunctioned during that time, and was replaced with a Wheelock MB-G10-24 motor bell (again, installed behind the grille where the old bell was.) The 4207+4004 panels still remain to this day.
