In case of an alarm, the user can explore the possible danger prior to the transmission of the fire alarm
to the fire brigade by using the
alarm delay procedure
with deadman´s handle.
The standard built-in
INFO-bus
makes the connection of a fire brigade control unit and of display de-
vices, transmission devices for remote indication units and of other information devices using wire-
saving technology possible.
A
32-bit high performance microprocessor
system together with additional extra auxiliary micro-
processors on the componentries is operated by a special real time multi tasking operating system and,
together with redundant logic for processing, provides clarity and security.
Open parameters of the control panel, parameters of detectors and modules, as well as display texts,
outputs and interfaces to peripheral devices emphasize the
universal flexibility
of the control panel.
The
parameters
of the control panel are set by the authorized installer either by using the keypad of
the control panel, by using a standard PC keyboard, or by using a PC (Notebook) and the comfortable
parameter setup software. Text, for example, can be entered or changed easily by using a PC keyboard.
The
power supply
from the mains power is ensured by a switched power unit with
50W rated power
,
that also supplies enough energy for the connected peripheral devices. Low current consumption, low
heat emission and by that, high reliability is guaranteed by the high efficiency of the switched power
unit.
A sufficiently dimensioned optional
stand-by battery
ensures that the fire detection system will con-
tinue to work unaffectedly for a long time in case of mains power shut down. The stand-by battery is
charged temperature-controlled by the power unit, and is secured against total discharge in case of
mains power shut down. The case of the fire detection control panel is built for accommodating the
stand-by battery.
An
optional case
with the same dimensions as the standard case is available to house a second set of
batteries (in case of increased power consumption), as well as for housing additional componentries for
expansion.
The
event memory
saves the last 500 events that have been registered by the control panel. You can
display the contents of the memory at any time on the LC-display. A filter enables you to limit displays
of the saved events by selecting events according to criteria that are needed frequently. The contents of
the memory are, like all other parameters of the control panel, preserved indefinitely in case of a total
power failure for unlimited time.
The built-in
clock
supplies the time-information for the display of events as well as for the events
saved in the memory. The switch between
summer- and wintertime
is automatic. The user can define
the date for the next two time switches in advance.
The
timer with weekly program
enables the timed switching of day operation of the control panel for
alarm delay operation of the transmitting device for fire alarm messages.
The connections for a tool for setting parameters or for an
external serial printer
are provided by
two
serial interfaces
. Since the interface for the printer has open parameters, the printer may be used as a
protocol printer, maintenance printer, to print measured values of detectors, or as a setup printer.
With the
AUTO-setup
feature the fire detection control panel recognizes all connected components of
the system and sets their setup to standard setup when it is put into operation.
Under normal circumstances, elaborate measures for compensating power spikes and high frequency
fields enable the control panel to operate in an
unshielded network
.
Remote maintenance
is possible with an optional interface converter that connects the fire detection
system to the Security System Manager (SAM) of LST.
Automatic fire detectors are in steady contact with the air of the surveilled area. Due to the dirt in the
air (e.g., dust), every detector will get dirty as time passes. Dirty detectors are one of the main reasons
