Fire Detection Systems & Fire 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.

Indication : AlgoRex CC1140 & CI1140 series
Detection : AlgoRex DS11 AnalogPLUS addressable detector range
AlgoRex® “Interactive”
AlgoRex® Interactive systems with AlgoLogic
utilises 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 & 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 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. Current Design Standards
