Instruction Manual of ATL-982 Fire Display Panel
------ Please read this Manual carefully before installing and using the product. -----
I. Product overview
TheATL-982 fire display panel (display panel for short) is a kind of microprocessor-controlled fire display
panel developed by our company. Each display panel is connected to a fire alarm control panel produced
by our company via a special RS-485 interface to process and display the data sent from the fire alarm
control panel. Each floor of a building may have a display panel installed. When there is a fire alarm on
the floor where the display panel is installed, or the neighboring floor above or below it, the display panel
will give a horn/strobe alarm and display the floor No., the room No., and some other position information
of the fire alarm.
II. Product features
Each display panel is connected with a fire alarm control panel via a RS-48 bus. At most 99
display panels may be connected with each RS-485 bus.
The display panels can display fire alarm messages or feedback messages only rather than fault
messages, action messages or other messages.
A fire alarm control panel may be used for setting the display area of a display panel. The set
display panel can display the fire alarm messages of the designated area (floor display) only.
Note: See the User’s Manual of the fire alarm control panel for the setting method.
It can replace a JB-FSD-981 fire display panel in a 2100 system.

3. Functions and usage of the product:
1）The displayed content
Fig.4 Normal Monitoring Status
If the display panel operates normally after startup, “The machine is operating normally,”as shown
in Fig.4 will be displayed. The current date and time are displayed at the top right corner of the
screen. The time is synchronous with that of the host machine of the fire alarm control panel and is
refreshed by it (there is some interval for refreshing). The currently supported control system is
displayed at the lower right corner of the screen. If “2100”is displayed, it means that a 2100
control system is supported; if 9000 is displayed, it means that a 9000 control system is supported.
The specific control system supported depends on the eighth digit of the address dial switch on the
back of the display panel. For more details, see 10) Setup of address parameters and control
system.
The display panel can display 99 fire alarm messages or feedback messages. When set to the
floor display mode, each display panel can display all the fire alarms of the floor. When there are
multiple fire alarms, the equipment will display them in an automatic rolling way. See Fig.5 for the

Red
It is out at ordinary times and will be lit in case of any fire alarm(s).
COMMUNICATION
Green
It blinks under normal circumstances and is out in case of a
communication fault.
FAULT
Yellow
In case of an equipment fault, the yellow FAULT indicator will be lit.
MUTE
Green
It will be lit after the system or the equipment is muted.
KEY
Green
If it is lit, it suggests that the keyboard lock is unlocked and all key
functions are enabled; if it is out, it suggests that the keyboard lock
is locked.
3）Functions of the keyboard lock
Keys SYSTEM TEST, QUERY, and RESET can be operated only when the keyboard lock is
unlocked, otherwise they cannot. After a combined password is set for the keys and keys KEY
(ENABLE/DISABLE), RESET and QUERY are pressed once in order, the keyboard lock will be
unlocked and the KEY indicator will be lit. After the KEY (ENABLE/DISABLE) is pressed again
after that, the keyboard lock will be locked again and the KEY indicator will go out.
4）Muting
After the SYSTEM MUTE key is pressed, the fire alarm tone will be eliminated, the MUTE indicator
will be lit and the normally closed contact of the relay will be closed. After receiving another fire
alarm, another horn/strobe alarm signal may be triggered and the MUTE indicator will go out
automatically.
Note: After receiving a MUTE command from an automatic fire alarm control panel, the display
panel can also realize the muting function.
5）System test
After the SYSTEM TEST key is pressed after the keyboard lock is unblocked, all the indicators on
the display panel will be lit, the buzzer will buzz and the LCD backlight will be lit too. Two seconds
later, all the indicators (except for the POWER indicator) will go out, the buzzer will stop buzzing,
the system test is completed and the equipment restores the status before the system test.
Note: The system test function is disabled when there is a fire alarm.
6）Reset

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.
