A JB-FSD-982 fire display panel consists of a base and a display panel. It is subject to a wall-mounted
installation. Its external wires may be directly connected with the terminals on the rear panel of the
display panel. See Fig.9 for the schematic diagram of the mounting base of the display panel.
Base fixing: Fix the base of the display panel on the embedded box.
Wiring: Connect the leads stretching out from the junction box with the terminals on the display panel
and do a correct wiring according to the contents marked on the terminals.
Fix the display panel.
Arrange the guide slot on the back of the display panel so it aligns with the mounting base and press the
display panel with a downward force along the wall until the guide slot fits the mounting base perfectly.
After that, lock the small hook on the upside of the back of the display panel with the guiding sheet on the
mounting base with some matched screws (see Fig.9).

and other defects.
The display panel is a precise electronic product and therefore needs to be managed by a specific
