5.2 Installation Technical Requirement
Fire alarm control panel should be in good earth protection. There is earth symbol inside
the panel.
Fire alarm control panel should be installed in the room or location where there is person
in charge. The distance from the panel bottom side to the floor should be 1.5 meters.
Both sides should have more than 0.5 meters space to make operation and maintenance
as easy as possible.
24V power supply line adopts fire resistant multi-core plastic flexible cable whose size
is no less than 2.5mm
2
. When the transmit distance is less than 1000 meters, the signal
line can be RVS-2×1.0mm
2
twin-color twisted multi-core plastic flexible wire. When the
transmit distance is less than 1500 meters, the signal line can
be RVS-2×1.5mm

Before debugging, construction side should install bus devices into proper positions and
connect them into alarm bus based on construction blueprint and various bus device
operation manuals.
