Fire Detection & Alarm Systems
Collective or Conventional Systems
The basic fire alarm configuration consists of a central panel with
detection devices and alarm sounders wired in a number of radial
circuits.
The control panel will indicate in which detection circuit (zone) an
alarm or fault condition has been generated and will operate common or
zonal sounders and auxiliary commands (for example door release or Fire
Brigade signaling).
Siemens Equipment Range:
Control and Indication : FC10 series, or AlgoRex CC1140
Detection : AlgoRex DS11 Collective ranges
Analogue Addressable Systems
This type of system improves dramatically on the basic collective
systems by using loop wiring, device isolators and software programming
to increase the system reliability and provide individual identification
of devices in alarm, fault or detector status.
In addition to the ‘normal’, ‘fire’ or ‘fault’ status the system is
capable of identifying detectors which require maintenance due to
soiling. The analogue signal is processed within each detector with the
status of every unit being available from the control panel at all
times.
This enables optimum service intervals and also relieves the effort
involved in performing costly periodic checks.
Siemens Equipment Range:
Control and Indication : AlgoRex CC1140 and CI1140 series
Detection : AlgoRex DS11 AnalogPLUS addressable detector range
AlgoRex® “Interactive”
AlgoRex® Interactive systems with AlgoLogic utilizes micro-processors
in every detection device. Fuzzy-neural software is included in each
detector which permits pattern recognition and provides discrimination
between real fires and false alarm phenomena.
This distributed intelligence approach pioneered in AlgoRex® allows the
fire system designer to select an algorithm for every automatic detector
to suit its particular application. Interactive takes its name from the
ability of the individual detectors to inform the user if a change in
its operating environment occurs.
This is known as an Application Warning. This advanced flexibility
allows the engineering of a fire detection system with high immunity to
false alarms at minimal cost.
Siemens Equipment Range:
Control and Indication : AlgoRex CC1140 and CI1140 series
Detection : AlgoRex DS11 Interactive Detection incorporating PolyRex®,
OptoRex® and ThermoRex® detectors, Linear Smoke detectors, Infrared
Flame detectors.
Sinteso™ Fire Detection Systems
Sinteso™ is the new fire detection system from Siemens consisting of
the two product lines C-LINE and S-LINE. With C-LINE the smoke and heat
signals are evaluated with detection algorithms (DA). With S-LINE the
smoke and heat signals are evaluated with ASAtechnology™. ASAtechnology™
stands for “Advanced Signal Analysis” and is based on application
algorithms.
The main difference to the C-LINE is in the technological sophistication
of the signal evaluation. To improve identification and visibility,
ASAtechnology™ has higher priority in media communications. Sinteso™
fire detection systems offer the best price / performance ratio in the
fire detection market.
The S-LINE range is intended for advanced applications where detection
is required as early as possible or for environments with a high
potential for false alarms.
The detectors have different algorithms derived from the latest
generation of applications (ASAtechnology™), and from which the
appropriate choice can be made depending on the circumstances.
The C-LINE range is intended for standard applications, where the
high-performance technology of the S-LINE detector is not required.
Nevertheless, the C-LINE includes detection features which are
comparable to those on the Siemens Interactive AlgoRex® detectors.
Siemens Equipment Range:
Control and Indication : Sinteso™ FS20 series, AlgoRex® CC1140 series
Detection: Sinteso™ Neural fire detectors, Wide spectrum smoke
detectors, linear smoke detectors, Heat detectors, Infrared flame
detectors

Siemens MM8000 Danger Management System incorporating Graphics
The MM8000 is a professional danger management and monitoring system for
integrating a variety of security and safety systems. Primary users of
the MM8000 are security guards and members of the fire brigade.
Other users are the shift managers responsible for investigating event
history and the creation of analytical reports based on historical data.
The system can be configured to provide text only display of the entire
sub systems or full graphical representation of the protected areas.
E100 Voice Alarm Systems
The E100 is a digital voice actuated alarm and evacuation system. The
system forms a new product family with various extension stages from the
stand-alone system right to the complex networking system that is linked
to the fire alarm system.
New European standards recognise that voice evacuation systems are
becoming an integral part of fire detection systems and need to be
treated with the same high standards.
These new standards are almost released and the E100 Voice Alarm system
has been specifically designed to meet them. The E100 Voice Alarm system
is fully compatible with our range of AlgoRex® and Sinteso™ fire
detection systems.
E100 complies fully with EN 60849 – electro-acoustical emergency warning
systems and the draft standard prEN 54-16.1 – Components for
voice-actuated alarms in fire alarm systems, voice-actuated alarm
centres.
