– part 1 Fire. In accordance
with these requirements, a hold-up time of 72 h (under certain conditions 24
h) with a subsequent alarm time of 30 min must generally be ensured by the
backup power supply. Deviating hold-up times may be selected for
applications that do not fall under these directives.
