1. INTRODUCTION
1.1 DOCUMENTATION CONTENTS
This Operation and Maintenance Documentation (OMD) presents the application, construction and
operation of the POLON 4900 fire detection and alarm control panel, constituting a part of the
POLON 4000 system. The Documentation contains information necessary in order to properly install,
operate and utilise the control panel. It may also facilitate the process of designing fire alarm
installations.
The Documentation does not include other POLON 4000 system elements which are described in
separate technical documents. The Manual is complemented with the Programming Manual (PM)
describing the control panel programming process. The line elements which interoperate with and
may be installed in the POLON 4900 control panel detection lines are listed in Appendix A.
The Operation and Maintenance Documentation is delivered to a user together with the control
panel; however, the Programming Manual is provided only for properly trained and authorised
designing and installation companies.
1.2 CONTROL PANEL APPLICATION
The POLON 4900 fire alarm is designed for:
-
signalling sources of fire detected by interoperating (automatic and manual) fire warning
devices;
-
defining locations endangered with fire;
-
activation of fire protection devices;
-
passing a fire information to appropriate services, e.g. National Fire Service units.
The POLON 4900 control panels are intended to operate continuously in premises of low dust
content, within the -5
o
C – +40
o
C temperature range and air relative humidity up to 80 % at +40
o
C.
1.3 SAFETY CONDITIONS
1.3.1 Electric shock protection
The POLON 4000 system fire control panels are ranked as 1
st
protection class devices and can be used
only in the case of application of additional protection against electric shocks, such as zeroing or
protective grounding.
Insulation of the 230 V/50 Hz power circuits is reinforced and resists the test voltage of 2800 V.
Insulation of low-voltage circuits (below 42 V) resists the test voltage of 700 V DC. After connecting
the power network cabling, the network connection must be protected with a manufacturer's
housing.
1.3.2 Installation and equipment safety
The wiring installation should be made of wires with the required fire resistance and it should be
properly protected when crossing the fire zone borders. In order to prevent unwelcome effects, the
distance between the low-voltage installation and the power and lightning protection systems should
be kept as required. Taking into account system resistance to electromagnetic interference, it is
recommended to use protective grounding. A reserve batteries cluster must be connected to the unit
during the final installation process stages.
The components of this unit are high-temperature sensitive. The maximum ambient temperature
must not exceed 40 °C. It is forbidden to block the ventilation openings on the side of the unit. The
