Knock Off Pull Stations which have a history of producing ground faults in systems
AIP Alarm Industry Products came on the market around 30 or so years ago a knock off of famous Edwards Brand products I am not sure if this was a Edwards division or they allowed there patents to be copied but they where well built and lasted for many years and where less cost then Edwards brand products. AIP produced mostly Pull stations and Heat Detectors but one persistent problem which has been cropping up is the pull stations tend to break down over the years and create ground faults especially if bumped. Plus the fact the screws are on the back one had to make sure a deep wiremold or other metal box was used to prevent ground faults in the first place.
