Protection against fire and panic risks in public
buildings/UTE C 12-201 guide
Art. EL 3, definitions: "Security installations are those that have
to be put into or maintained in service to ensure the evacuation
of the public" or facilitate the intervention of the first-aid
Art. EL 16, power supply circuits in security installations section
1a: "…the corresponding junction or deviation devices and their
enclosures except for the waterproofing systems must satisfy
the incandescent cable test defined in the standard in force, the
temperature of the incandescent cable being 960 °C"
Viking 3 terminal blocks satisfy the incandescent cable test 960 °C
according to standard IEC 60695-2-11
