Power supply
The alarm-ready status in the fire protection system and the aperture of an
alarm are taken into account when rating the external mains supply. In the
system's alarm-ready status, the mains supply must supply standby current
to the air sampling smoke detection systems and ensure that the emergency
power batteries are charging in accordance with DIN VDE 0833 Part 1 (80%
load in 24 hours).
NOTICE
The mains supply of the air sampling smoke detection systems shall be
approved according to EN 54-4.
