6.3 DESIGN GUIDELINES
In order to ensure reliability of installation operation, the loop system of routing detection lines should
be employed. Radial lines should be used in special circumstances (e.g. when a few detectors must be
installed at a considerable distance from the system).
While designing an addressable detection line, each addressable line element must be provided with its
address (element number) to be identified by the control panel. In order to create a clear design and
streamline the service process, it is recommended that the consecutively installed line elements have
increasing address numbers. The best solution is to assign the numbers according to the algorithm used
by the control panel to number elements during the automatic configuration process.
The ADC-4001 adapters have a built-in LED informing about actuation of a detector in a side line. Due to
the above, an ADC-4001 adapter may be installed at an entrance to the room, instead of an actuation
indicator. Regardless of the above, it is also possible to connect WZ-31 actuation indicators both to the
detectors operating in the ADC-4001 adapter side line and 4046 series detectors.
In the POLON 4000 system, screened cabling should be used.
While designing the installation, all requirements defined in the technical data must be met. Special
attention must be paid to the capacity of an addressable detection line. Moreover, proper resistance of
the detection line and proper resistance of the line between the neighbouring short circuit isolators
must be ensured.
7 ALARMING ARRANGEMENT
Organisation of the alarming procedure and other programmable parameters the POLON 4500 control
panel must be defined during the installation designing stage. To this end, taking into account the
conditions existing in the protected premises, the designer's tables must be correctly filled in. These
tables are an integral part of a design and must be made available to the commissioning and service
personnel.
The organisation of the alarming procedure is programmed as follows:
-
declaring addressable elements, assignments to zones, operation modes and groups;
-
declaring alarming variants and user's messages;
-
programming general alarming parameters (T1, T2, T3 times).
7.1 DETECTION ZONE
Addressable elements must be program grouped in detection zones. It is possible to create max. 1024
zones in the control panel and the zones number 1, 2, 3 and 4 are permanently defined as fire
extinguishing zones. According to the standard, max. 32 line elements may be assigned to one zone.
Zones to which no element has been assigned are referred to as empty or inactive zones. The zones are
created to describe a given detection area with a given set of line elements in a manner making it
possible to identify the installation location. Moreover, a zone allows programming a given alarming
variant in order to eliminate false alarms in facilities where the risk of accidental actuation of fire
warning devices is high.
An area of one zone may be divided into two groups of fire warning devices, defined as A and B. Each
fire warning device must be assigned to one of these groups during the programming process. The
groups of fire protection elements (A/B) are created in order to program coincidental variants of zone
alarming in order to eliminate false alarms as much as it is possible.
The program makes it possible to provide each zone with a text message (user message) containing two
lines of text and max. 32 characters in each line.
