In the early sixties Pyrotronics (Now Siemens Industry/Fire Safety) manufactured Pyr-A-Larm High Voltage (220VDC) fire alarm systems (FIU-2, FIU-6) that utilized a variety of initiating devices including but not limited to Ionization Detectors using cold cathode tubes (F-5B, F-3/5A). While manufacturing has long ceased many of these systems are still in service today with a variety of aftermarket vendors supporting them. Google those model numbers and they can still be found.
While were on the topic of legacy stuff, Pyrotronics System-3 (circa 1970's) is still in production. This manufacturer was akin to western electric and manufactured robust fire protection products, the longevity is a testament to a bygone era.
