Scope
These planning instructions serve to ensure correct planning, installation and commis-
sioning of Fire Detection Systems (FDS). As a general rule, local national installation reg-
ulations must be complied with providing they do not impair the reliable operation of the
fire detection system. They are not listed here.
Explosion-proof detectors and line network
For detailed information concerning planning, installation and commissioning of systems
in explosion-hazard areas see document e1204, «Fire detection systems in explosion-
hazard areas».
This document is intended for planning engineers in all national sales organiza-
tions. Local standard practices, regulations, languages etc that vary from this doc-
ument must be taken into account and and documented by the national sales orga-
nizations.

1.3 Fire detection system line network
1.3.1 Separate line network
The fire detection system must be basically operated via a separate line network. The
common use of a main cable (e.g. PTT) is not recommended.
Never use low voltages and extra low voltages in the same main cable.
1.3.2 Design
According to block diagram.
Maintain separation of low voltage and extra low voltage cables.
1.3.3 Wiring material
Basically, standard telephone and extra low voltage installation material can be used.
Twisted cable is preferred and is sometimes essential.
In order to ensure alarm activation in any situation, we recommend cables which are fire-
resistant over a longer period.
1.3.4 Existing line networks
These networks can be basically used if capacitances, line and insulation resistances
comply with the data specified.
1.3.5 Explosion hazard areas
For explosion-hazard areas, comply with the guidelines according to document e1204,
«Fire detection in explosion-hazard areas».
1.3.6 Electromagnetic influence (EMI)
All equipment is largely protected against EMI.
Nevertheless, the following precautions are necessary:
Maintain the greatest possible distances from thyristor control cables, high voltage
lines, lightning protection systems, transmitter cables etc.

1.3.7 «Collective» detection lines
«Collective»detection lines can only be installed as stub lines. According to the type of
control unit or regulations, 20...32 fire detectors can be connected per stub line.
New systems: Twisted cable, in exceptional cases with very powerful electromagnetic
influence shielded and twisted.
Existing systems: Single and parallel conductors are permissible.
Line resistances and line capacitances see document e1508 «Connection factors, line
resistances and capacitances».
