(11) TERM: Termination of
databus. Only to be used on
first and last device on the
local databus.
Connecting ATS1201 to the control panel
The system databus is used to connect data gathering panels
(to provide extra zones) and remote 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 (WCAT 52 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 "−".
Figure 3 shows the preferred system databus wiring.
The TERM link is on the first and last devices on the system
databus. In a star-wiring configuration, the TERM link is only
fitted on the devices at the ends of the two longest system
databus cable runs.

Refer to ATS control panel installation guide for a more
detailed description of the cabling.

(7) Separate 12 V power supply
(required if RAS is more
than 100 m from the nearest
panel or DGP. Connect the
negative terminal of the
power supply to the "−" wire
of the databus.
DGP DIP switch settings
•
Address: Select DGP address. Set switches 1 to 4 to Off
to disable the DGP. See Figure 2 for correct address
settings.
•
A: Set to On when 2 or 3 ATS1202 zone expanders are
connected to J5. Otherwise set to Off.
•
B: Set to On when ATS1811 (8-way relay card), or
ATS1820 (16-way open collector card) or ATS1821 (8-way
open collector card) is connected to J8.
Off: No ATS1811, ATS1820 or ATS1821 connected to J8.
Use this setting also if an ATS1810 (4-way relay card) is
connected to J8.
•
C, D: Not used. Set to Off.
LEDs
•
Tx: Red LED flashes when panel is polling remote units. It
must always be active.
•
Rx: Yellow LED flashes when remote units (RAS and
DGP) are replying to polling.
Earthing
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 separate 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 Figure 5) 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.
