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 also Cabling ATS1201 on page 5.
11. Mains connection
Make sure that before connecting the mains power, the
mains power supply is disconnected (see page 4).
When installing the mains power, use strain relieves like
cable ties and coupling PG16's to ensure proper wiring.
In all cases, local regulations should be applied.
12. Earthing (see
WARNING!
!
Correct earthing procedures 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 earthen
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
isolator/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 Fig. 3) 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.

Output numbering
(*max. 255 outputs)
A DGP can have a maximum of 16 outputs available as
relays or open collectors outputs. The output numbers
are the same as the 16 zone numbers allocated to the
DGP address.
Important:
All outputs are available on the control panel for
programming. However you can only fit 16 relay cards
(ATS1811 or ATS1820), taking into consideration the
load on the Clock-out Interface of the output expansion.
ATTENTION!
!
If six or more relay cards are used, an
external power supply is required to power
the relay cards
Zone numbering
(256 zones)
The ATS 1201 has 8 zones that can be expanded using
the ATS 1202 (8 zones) to a maximum of 32 zones. If
the number of zones exceeds 16, then the zones are
taken from the next DGP address and DGP ceases to
exist.
e.g.
DGP 1 has 24 zones (zones 17 to 40). The
next DGP in the system must now be addressed and
polled as DGP 3, because zones 33 to 40 on DGP 1
have taken from DGP 2.
The unused zone numbers in the system (zones 41 to
48) must be programmed in the zone database as Type
0.
