Honeywell ESSER 8010 Operation And Installation Instructions Manual page 25

Cable entry and installation
Use only the proper cable entries. Use separate cable entries and cable glands for the power supply and signal
lines. All connected voltage and signal lines must be installed with suitable fixing material, such as plastic cable
fasteners so that they cannot move around. It is important that the power supply line cannot touch the signal
lines (SELV). Work may be carried out on the fire alarm system only when it is voltage free (network and
emergency power supply).
The devices installed in the 19-inch cabinet must be protected against inadmissible moisture. To ensure this, all
installation cables must have suitable cable packing before they are fed into the 19-inch cabinet.
Accessibility
The 19-inch cabinet must be accessible at all times for operation and maintenance work.
Ground
Even when switchgear is installed carefully and properly planned in advance this cannot completely prevent
undesired short circuits during operation of the fire alarm system. The corresponding safety measures must be
taken to reliably prevent damage to life and property in such cases.
If two or more panels are installed in the 19-inch cabinet, the following instructions must be
complied with:
Each panel must be connected to the terminal strip with a separate PE cable (required cable
cross-section 〈 1.5 mm²). Place the reference to leak current next to the terminal strip.
You will find further information about the required type-relevant grounding in the section on PE
connection and power supply.
Openings and cable entries
Unused cable entries must be closed with suitable material. Open installation spaces in the pivot frame must
also be closed with filler plates.
Emergency power supply
The emergency power supply for the extinguishing agent control system is provided by batteries, which are
installed at specific points in the housing of the extinguishing agent control systems. The batteries must always
be protected against movement. Batteries with a capacity of ≥ 12 Ah must not be connected. When installing the
batteries pay attention to the installation position (see battery label).
EMC protection
The fire alarm control panels are fitted - by factory settings - with an EMC secondary protection system. Use
only approved protection modules for any additional required EMC-protection of power supply units and cabling.
Danger – Electrical shock !
Remove all power from the panel before carrying out any installation work!
ESD / EMC protection
While handling electronic assemblies, the necessary precautions against electrostatic discharge
must be taken.
Protective and functional earth
The PE conductor must be connected to the corresponding terminal at the mains supply.
Connect the FE terminal of the panel's cabinet with the PE rail of the power distributor panel
from which the fire alarm system will be powered.
