5 OPERATION DESCRIPTION
5.1 GENERAL DESCRIPTION
The POLON 4500 automatic fire extinguishing control panel (of the POLON 4000 system) is a multi-
processor device of a modular design. The control panel block diagram is presented in Fig. 5.1.
The POLON 4500 control panel is divided into two independent, but closely co-operating units:
-
fire detection unit fulfilling the same role as in the POLON 4900 fire alarm system;
-
fire extinguishing unit which may operate from 1 to 4 fire extinguishing zones (depending on its
configuration).
Within the detection unit, after receiving a proper signal from the control panel (element address), line
elements installed in the addressable detection line transmit return signals with information regarding
their type and status. The exchange of information between line elements and the control panel is
possible through the four-loop MSL-1M module. Having analysed the received signals, the MSL-1M
module transmits required information (through the control panel bus) to the PSC-46 central controller
being the main module of the control panel. PSC-46 processes the information and provides correct
signals for other systems.
While implementing the programmed operation procedures, the PSC-46 controls (through the bus) the
relays or signalling lines in the PPW-45 module, LCD display and signalling/handling elements (only in
the detection unit) of the TSO-4500 board. The board is responsible for communication between the
operating personnel and the control panel.
The PPW-45 programmable outputs module makes it possible to control external devices by means of 8
relay outputs, 4 control lines and 4 monitoring lines.
The MSG-45 modules (one per each fire extinguishing zone) are responsible for controlling extinguishing
and signalling devices in the fire extinguishing zones. Each module is connected to own signalling and
handling elements on the TSO-4500 board and the main PSC-46 module which emits alarm signals
necessary to activate the fire extinguishing procedure. During the hardware/software setup, the
modules obtain logical names (from MSG-1 to MSG-4 as required) in order to identify them with the fire
extinguishing zones from 1 to 4.
The MZ-48 power supply module generates the following voltages:
-
+ 24 V operating voltage of the control panel and voltage for users;
-
ins 27 V voltage to supply detection lines;
-
ins 5 V supply voltage for serial outputs;
-
+ 5 V supply voltage for the LCD display and DR-48 printer.
The AC power adaptor (capacity 30 V/10 A) supplies the operating voltage to the control panel and,
in the event of mains power failure, the voltage is supplied from the reserve battery cluster.
5.2 TSO-4500 OPERATOR PANEL
The TSO-4500 operator’s panel contains:
- liquid crystal display
- PS-48 signalling devices board
- PP-45 intermediate board
- PO-45 service panel ( signalling diodes)
- DR-48 printer.
The LCD display in mechanically and electrically connected with the PCS-46 main controller located on
the control panel door.
