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».

2 Installation
2.1 General
2.1.1 Responsibility
The planning engineer is responsible for the correct installation of the fire detection sys-
tem. He is responsible for positioning equipment correctly and preparing the necessary
documentation.
The electrician is responsible for the line network and the wiring up of the equipment as
well as the permanent mounting of devices.
2.1.2 Storage of equipment on site
The installer is responsible for the storage and safety of equipment.
Store equipment in a dry, clean room.
Leave equipment in its original packing until required for use.
Only insert fire detectors, control unit modules etc. when commissioning the system.
2.1.3 Installation documentation
The following installation documentation must be provided by the planner for correct
installation:
Ground plans with equipment locations drawn in and/or
Lists of equipment indicating the location of equipment
Block diagrams with the architecture of the supply network.
Connection diagram for equipment, intermediate distribution frame, control unit and
terminal
Information on the use of special cables, explosion-hazard applications etc.
2.1.4 Marking of equipment
If required, two different designation plates are available for the marking of detectors.
They are attached under the detector base after installation.
As component parts of a fire detection system, terminal boxes, distributor boxes, loop-
ing-in boxes must be marked accordingly.

e1453b

Fire & Security Products
Siemens Building Technologies Group 12.2001
2.2 Installing the equipment
2.2.1 Mounting
Equipment must be solidly mounted.
When detectors are inserted, detector bases are subject to pushing, pulling and shearing
stress and must be mounted accordingly. There must be at least 50cm free space be-
neath the detector for test purposes.
Detector bases must lie flat on the ceiling (do not mount on bumps or hollows, concrete
ridges etc.).
Concrete ridge
Fig. 10 Detector base mounted on concrete ridge
= distorted detector base = system fault
Fire detectors must be easily accessible for regular servicing.
The response indicator in the base must be easily visible from the alarm investigation
route.
Response indicator
Fig. 11 Response indicator clearly visible
See product packing sheets, for further details.

Fire & Security Products
Siemens Building Technologies Group 12.2001
2.2.2 Cable entry
Cables must be fed tightly through the rubber membrane in the base in order to prevent
condensation and air penetrating to the base/detector. Air «rinsing»arises due to differ-
ences in pressure in different rooms caused by air conditioning and ventilation systems.
Pressure compensation also arises through the cable conduit which to some extent
causes powerful air currents behind the base. This prevents smoke from properly enter-
ing the detector.

holes or slits!

2.2.3 Wiring for damp environments
Equipment which is mounted in damp rooms must be provided with special cable entries
(screwed cable glands). Suitable adapter bases are available for this purpose.

2.2.4 Line terminal
The DS11 base contains spring terminals. To ensure good contact, only one wire must be
connected per terminal. Auxiliary terminals are available for multiple connections. (see
connection diagram on product enclosure sheet.)
2.2.5 Earth connection
The control unit and terminal with power supply must be earthed according to local regu-
lations.
The other equipment in a normal fire detection system does not require an earth con-
nection.
Shielded cables must be earthed in a star-pattern at one point (control unit). Shielding
must be through-connected in all equipment using insulated auxiliary terminals. Shield-
ing must not come into contact with any external earth potential or metal parts of the
equipment.
Equipment for explosion-hazard areas must be installed and earthed according to docu-
ment e1204, «Fire detection in explosion-hazard areas».
