1.4 System equipment
As shown in Fig.1-1, in addition to a fire control unit, the system also includes other
corresponding equipment. To acquaint you with the system, we will introduce its equipment
briefly below. The fire control system includes the following main components:
Main control unit
The main control panel processes and analyzes the data information transmitted from other
components of the system and commands other components of the system to execute the
corresponding commands according to the results of data analyses. For example, it can make
the buzzer give a fire alarm.
Display component
The display component provides a main output interface for alarm information and the daily
maintenance and query interfaces as well.
Input equipment
The system is transplanted with a standard external peripheral interface for computers and
uses a PS/2 keyboard and mouse as input equipment, which makes system setting and
maintenance highly convenient for users.
Power supplies
They provide electricity for the internal equipment of the entire system. The system has
special fire equipment power supplies with an output voltage of DC 24V. The power supplies
can provide alarm or feedback signals like AC FAULT, DC FAULT, DC LACK, DC CHARGE
and have an excellent anti-interference characteristic.
Interface board
It is a driver board for the detector or module bus. Each interface board has two circuits. Each
of the two circuits can drive 324 intelligent detectors or modules.
Fire detector
The system can be accessed to multiple intelligent smoke, heat or composite detectors
produced by Fanhai Sanjiang. The main fire detector models include JTY-GD-930, JTW-ZD
-920 and so on.
Input module, output module, audible and visual alarm, manual alarm and
fire hydrant
The system may be accessed to multiple intelligent modules produced by
kai wei xin
.
The main product models include JK-952 (input module), JS-951 (input module), KZ-953
(output module) and KZJ-956 (I/O module). Meanwhile, the system may also be accessed to
an SG-991 intelligent audible and visual alarm, a J-SAP-M-960 intelligent manual alarm
button, a J-SAP-M-961 intelligent fire hydrant, etc.
Bus manual control panel
Each manual control panel has 30 manual control buttons each of which corresponds to an
I/O module on the bus. In the permissible manual control state, pressing such a manual
control button can realize manual start and stop operations of the corresponding I/O module.
Multi-line linkage control unit
Each group of DX900-05A multi-line linkage control units include 5 multi-line control points
that may control five pieces of key equipment needing direct control, such as fire pumps, etc.
A 2U panel may be installed with 15 multi-line linkage control points (three units).
Printer
The system has a standard special mini printer (printer for short) that may print information like
alarm information, feedback information, fault information and some other information for
future reference.
