Introduction to system constituent equipment
As shown in Figure 1-1,in order to familiarize you with this system, the constituent equipment
is introduced briefly in the following sections. The fire control system is composed of the
following main constituent parts:
Main control part
The main control part is responsible for processing and analyzing the data messages
transmitted from other parts, and directing, based on results of data analysis, other parts in
the system to executive corresponding orders, such as controlling the fire alarm sounding by
control buzzer.
Display component
The display component provides main output interface for alarm message and routine
maintenance and query interface.
Input device
The system transplants the computer standard peripheral interface, panel buttons or
USB-interfaced keyboard / button as input devices, which brings much convenience for the
user to set up and maintain the system.
Power supply
The power supply is used for all internal equipment in the overall system. The system adopts
the special firefighting equipment power with DC 24V output, which can provide alarm or
feedback signals, such as main electrical faults, backup electrical faults, backup power
under-voltage and backup power charging, and have good immunity characteristics.
Bus
The bus is used as the driver of detector/module bus, which may drive 324 intelligent
detectors or intelligent modules and can be equipped with bus indicating panel.
Fire detector
The system can get access to various intelligent smoke, thermal or compound detectors
produced by the company, and the main types include JTY-GD-930 and JTW-ZD -920.
