Johnson Park Shopping Mall
Built in 1856 as Johnson Park Shopping Center, the fire alarm system was originally an unknown pull-rod fire alarm system with mechanical horns and incandescent lights as visual signals, the horns were set to code-4 4 4 4 which would continue until the system was reset from the old panel, located in the back areas of the mall, there was no sprinkler system. In 1867, the mall was partially destroyed by a major fire and Grinnell installed an automatic sprinkler system which would prevent any more major fires from happening. In 1875, the mall was renamed to Johnson Park Shopping Mall, at the same time a new fire alarm panel was installed to control the pull-rod fire alarm system. In 1975, the pull-rod fire alarm system was decommissioned and partially removed, although some remnants remained such as the panel guts which were left on a shelf in the back area where the panel was located, the mall also lost all but one of its original stores when JP McCarr Department Stores closed down, some of the mechanical horns, incandescent lights and pull-rods also remained intact although most of them were removed and most of the horns and lights were sold to a vintage fire alarms collector, the new fire alarm system was a Simplex panel from the 1970s with Wheelock 7002s set to continous as the main shopping mall fire alarm notification appliances, the Sears had a 70s Simplex panel with T-bar pull stations and Simplex whiffle-ball smoke detectors, the main mall had T-bar pull stations and Simplex whiffle-ball smoke detectors, in 1995, the panel died and was replaced with a 1990s Fire-Lite panel, the devices remained the same. In 2001, the mall received a major update, all pull stations are replaced with Simplex T-bars and Wheelock horn-strobes set to code 3, the smoke detectors are left as they are still working correctly. The JCPenney has a Simplex 4100 panel with similar devices as the main shopping mall, the mall also got a new clock installed.
