Honeywell ESSER 8010 Operation And Installation Instructions Manual page 31

The power supply of the Extinguishing Control Computer 8010 is provided via the integrated power supply unit.
If necessary, an increased power requirement for external devices, e.g. caused by longer cable lengths, must
be compensated for with an external voltage supply via a separate power supply unit. In case of an AC main
power loss, the continuous voltage supply is ensured by the batteries. If the mains voltage is not present after a
delay time of 15 minutes (900s) a fault message is indicated. If the failure cause is eliminated within this time no
fault message will be generated. At a total loss of the mains and battery voltage, a system start will be
automatically carried out by the CPU if the main voltage supply (not the battery voltage) is present again.

The PE-connector of the mains terminal X2 is connected to the housings rear side with a prefabricated cable.
This connection must not be disconnected!
•
The 230 V AC mains supply must be installed in accordance with local regulations by a qualified technician.
•
The Extinguishing Control Computer must be supplied from the 230 V mains through a separate isolator or
an appropriately labelled safety switch. In buildings fitted with earth fault devices (FI protection), a separate
device must be installed for the fire alarm system.
•
Use an appropriate mains cable, e.g. NYM 3 x 1.5 mm
•
The installation must comply with local regulations on electrical safety
To prevent short circuits
Remove all power (mains and battery) from the Extinguishing Control Computer before any work
is carried out.
All connected power and signal lines must be secured using appropriate fasteners, e.g. plastic
cable binders. Make sure the mains cable will not move and touch the signal lines. Make sure to
lead all cables complete with their outer sheaths intact into the cabinet. Only remove the insulation
from those sections which are inside the cabinet.
Power supply fuse
The fuses cannot prevent an unexpected fault in electrical modules; rather, these fuses are
intended to protect users and their surroundings from damage.
Therefore, never repair or bridge the fuse that is installed or replace it with anything other than the
stated type!
