Take care that the NTC is positioned in free air far from the
heat sink or any other component. Its function is to measure
the batteries working temperature inside the cabinet. The
following table should be taken into account to measure the
charge voltage.
•
15°C: 13.74 V
•
20°C: 13.65 V
•
25°C: 13.56 V
•
30°C: 13.46 V
•
35°C: 13.37 V
Measure the voltage at the battery terminal (Batt + and
−) with
no battery attached.
Cabling ATS1203(N)/ATS1204(N)
Note:
Preferred system databus wiring
— see Figure 4. Refer
to the ATS control panel installation guide for a more detailed
description of the cabling.
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.

(2) ATS control panel.
(3) ATS1105 LCD RAS (TERM switch not set to ON).
(4) Separate 12 V power supply. (Required if RAS is more than
100
m from the nearest panel or DGP. Connect “−” to “−” of the
databus).
(5) Preferred data cable type is WCAT 52 (2 pair twisted).
(6) TERM link fitted (last device on local databus).
(7) Earth connection to connect shield [1].
(8) Any data gathering panel like ATS1201, ATS1203, ATS1204,
ATS1210, ATS1220 or ATS125x.
[1] Connect cable shield to one device only.

“System databus connection” below and “Earthing” below.

Notes
•
If the battery load resistor is enabled, output 8 is no longer
available for non-clocked output expansion boards.
•
The battery load resistor setting must correspond with
DGP programmed settings. See
on page 7 for details.
•
In case the DGP is set for 2 DGPs to enable all 32
outputs, the control panel programming should be set up
to poll the DGP address and the a 1.
Links
•
TERM: Termination of databus. Only to be used on first
and last device on the local databus.
•
+12V: C12 VDC to output board.
DGP DIP switch settings
See Figure 2.
Address: Select DGP address. Set switches 1 to 4 to OFF to
disable the DGP (see Figure 2 for correct address settings).
LEDs
•
Tx: Red LED flashes when remote units (RAS and DGP)
are replying to polling.
•
Rx: Yellow LED flashes when panel is polling remote
units. It must always be active.
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 panel.
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 or any other earth point. However it
should be left disconnected at the 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 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 “−”.

“Cabling ATS1203(N)/ATS1204(N)” above.
Earthing
See Figure 3.
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).
