4 ATS4000 Installation and Quick Programming Guide
5. System databus connection
The system databus is used to connect Data
Gathering Panels (to provide extra zones) and
Arming Stations to the ATS control panel. Remote
devices can be up to 1.5 km from an ATS control
panels.
Arming stations and Data Gathering Panels must
be connected via a 2 pair twisted shielded data
cable from the system databus connection.
(Belden 8723 is recommended)
The shield of the data cable should be connected
to earth at the ATS control panel and should be
left disconnected at any other end.
It is recommended that where the distance
between the arming station and the nearest
device is more than 100 meters, a separate power
supply must be used to power the arming station.
To power the arming station, do not connect ‘+’
from the system databus. Connect '+' of the local
power supply to '+' on the arming station and
connect 0 volts from the power supply and 0 volts
from the system databus to the arming station
terminal marked ‘-’.
See Cabling on pages 3.
6. Earthing
WARNING! Correct Earthing
procedure must be followed.
• Earthing of one cabinet containing several
devices.
All devices designed for the system have earth
connections via metal studs to the metal housing.
Take care, that these metal studs make good
connection to the housing (beware of paint).
The earth connections of every piece of
equipment in the system can be used for
connecting the shielding of shielded cables.
If a device is placed in a plastic housing the earth
lug of this device does not have to be connected.
• Earthing panels in a single building.
In one building several cabinets or devices are
earthed to safety ground.
The safety earth of this building has to be checked
by a licensed contractor.
• Earthing panels in more buildings.
If the wiring extends to separated buildings, more
than one common earth system will be used. Use
isolater/repeaters ATS1740 to isolate the system
databus. In this way the system is protected
against variations in earth potential.
Shielding
The shielding of all shielded cables used in the
system should only be connected at ONE side to
one common earthing point in a building (see
figure). If a shielded databus cable is routed via
more than one plastic device, the shielding from
incoming and out-going cable has to be
connected.
