7）Query
After the equipment receives two or more fire alarm messages, it will display the fire alarm messages automatically
and circularly. After the QUERY key is pressed after the keyboard lock is unlocked, the equipment will enter the
manual display status. Each time after the QUERY key is pressed, the equipment will display the next fire alarm
message. If the QUERY key is not operated within eight seconds, the equipment will automatically return to the
circular display status.
8）External relay
The equipment includes a group of relay external control contacts (normally open or normally closed). After the
equipment receives a fire alarm message, the external relay will be started. Status of the external relay: Under
normal circumstances, OFF and COM are closed and ON and COM are open; in case of a fire alarm, OFF and
COM are open and ON and COM are closed.
9）Communication indication
When the display panel is communicating with the automatic fire alarm control panel normally, the
COMMUNICATION indicator on the display panel is on, which indicators normal communication.
10）Setup of address parameters and control system
During the installation of the display panel, its address must be set according to the specific installation location.
The address is set through a JP3 dial switch on the main board on the back of the display panel (see Fig.2 for its
location). The JP3 dial switch has eight dial digits in all, wherein the first to the seventh digits are used for setting the
address (see Fig.6 and Fig.7), and the eighth digit for choosing the 2100 control system or the 9000 control system.
If the JP3 dial switch is pulled to the ON position, the 9000 control system will be chosen (see Fig.6); if it is pulled to
the OFF position, the 2100 control system will be chosen (Fig.7). Corresponding content is displayed at the lower
right corner of the screen.
Fig.6 Address Codes of the 9000 Control System Fig.7 Address Codes of the 2100 Control System
If the short-circuit block is pulled to the ON position, the digit will be set to be “0”; if it is pulled to the OFF position,
the digit will be set to be “1.”Address setup is calculated through a binary coding method (popularly speaking,
binary numbers like 1, 2, 4, 8, 16, 34, 64 and so on are used). For example, if the JP3 dial switch is set to be
“1000000”(see Fig.6), the address will be 1+0+0+0+0+0+0=1; and if it is set to be “0100100”(see Fig.7), the
address will be 0+2+0+0+16+0+0=18.
VI. Installation and wiring
A special base is necessary during the installation of a display panel. As shown in Fig.8, the external
dimensions, the mounting hole diameter and the mounting hole spacing of the special base are
101.5mm×14mm×86mm (L×B×H), 4.5mm and 58mm～62mm respectively.
