Fire Alarm Computer 8000C
1 General
To equip buildings, facilities, commonly-frequented areas and working spaces with a fire warning
system can only be carried out economically and with reasonable propriety when correspondingly
well-founded safety concepts are developed and accordingly applied.
Wherever the highest requirements are made on a fire warning system, whether in small
commercial facilities or in industrial plants, the Fire Alarm Computer 8000C transforms safety
techniques and economy into practical reality. The modular design with different micro modules
and individual extension concepts allow the Fire Alarm Computer 8000C to be easily adapted to
special requirements. The Fire Alarm Computer 8000C represents the most modern standard of
fire warning technology. A reliable fire warning facility is guaranteed by the application of
"intelligent" fire detectors connected in an analog ring loop which is tolerant to short and open
circuits.
In this ring loop - the esserbus
®
- up to 127 bus subscribers each divisible into 127 individual
detector zones can be connected with an overall cable length of up to two kilometres. The
esserbus
®
is a two-wire line supplied and monitored at both ends in ring topology. The Fire Alarm
Computer 8000C automatically registers the wiring of the ring loop and determines the logical
addresses of the individual bus subscribers. A separate adjustment of the addresses of the
individual bus subscribers is unnecessary.
Subscribers in the esserbus
®
are automatic and non-automatic intelligent fire detectors, technical
alarm modules (TAL) and the specially developed esserbus
®
transponder input/output devices.
These esserbus
®
transponders are bus subscribers with freely programmable inputs and outputs,
for example for the activation and monitoring of external devices such as display panels, alarm
devices, door closers and other connected equipment.
Using the essernet
®
safety network, 31 Fire Alarm Computer 8000C or other network subscribers
such as display and operating panels or alarm devices can be connected in a homogenous
network. Operation of the fire warning system, e.g. switching off a detector zone, is possible from
any fire alarm control panel or operating panel in the essernet
®
. Signals such as alarm, trouble,
disconnection or other events are transferred to all subscribers in the essernet
®
and can be
accessed from any desired position. Data exchange can, according to the transfer rate, be carried
out either with a twisted pair or a LAN cable. The essernet
®
communications protocol guarantees
reliable data exchange even if a short or open circuit occurs in the network.
These Operating Instructions are intended to aid you in the operation of the Fire Alarm Computer
8000C in addition to the description provided by the specialised installer and should be kept
together with the technical documentation of the fire alarm system. If you have any questions,
please consult your specialised installer.
The operation of an installed and operative fire alarm control panel may only be carried out by
authorised and trained persons under observance of the safety precautions and, if necessary, in
collaboration with the assisting institutions (e.g. fire department).
