Tamper switch
The ATS1197 tamper switch is closed when the unit is fitted on
the mounting plate. In operation, the LCD display will show
"RAS Tamper" when not closed.
RAS DIP switch settings
A row of DIP switches is located on the rear of the RAS
(Figure 2) and is used for setting the RAS address and the bus
termination (TERM) condition. These settings are described in
the following sections.
1. RAS address (item 1): Set the RAS address using
switches 1 to 4. Switch in "up" position is off, and switch in
"down" position is on.
2. TERM switch (item 2): Use switch 5 to set TERM to On, if
needed. There must be no more than two TERM switches
or links set to On for any bus. Refer to the control panel
installation guide for details about the use of TERM
switches or links.
Note:
On is indicated as black (down). Example: RAS 2 = On,
Off, Off, Off.
Connections
Colour
Application
Red
+12 V nominal (8.5 to 14.0 VDC supply)
The RAS can be powered using the bus + and
−
power from the control panel if the distance
between the RAS and the control panel does not
exceed 100 m (328 feet). Otherwise the RAS can
be powered by AUX PWR from a DGP, or by an
auxiliary power supply.
Black
0 V (DC supply ground)
Green
D0/D
−/Clock, may be used for D0 (Wiegand data),
D
− (RS485 data), Magnetic stripe clock. Normal
operating voltage 0 to +5 V (absolute maximum is
+12 V).
White
D1/D+/Data, may be used for D1 (Wiegand data),
D+ (RS485 data), magnetic stripe data. Normal
operating voltage 0 to +5 V (absolute maximumis
+12 V).
The RAS is connected to the ATS panel via the
RS485 data bus, up to 1.5 km from the control
panel or the 4-door DGP. Use the 2-pair twisted,
shielded data cable (WCAT52/54 is recommended).
The shield of any bus cable must be connected to
system ground at one end only. The ATS111x RAS
is not provided with an Earth connection for this
purpose. If the bus is ‘daisy-chained’ to the RAS,
ensure that the shield of the cable is joined to
provide continuity of data cable shield.
Blue
Buzzer/Beeper, may be used for offline buzzer
control.
Wire open or +5 to 12 V: buzzer off (absolute
maximum is +14 V).
Wire grounded (0 V): buzzer on.
Brown
Application depends on selection of RAS menu
option 2-Offline LED control. See programming.
Colour
Application
Yellow
Application depends on selection of RAS menu
option 2-Offline LED control (see programming).
When not used for two wire LED control, yellow wire
may be used for
RTE input when online to ATS,
connection to a simple push button for operation in
RTE Only mode,
connection to a button for use in RTE + Arm/Disarm
mode.
Button should be connected to GND. See 10-RTE
(Egress) Control.
Violet
Open collector output, configurable as Door output,
Tamper output, or magnetic stripe data present.
This is a low current output and must not be used to
directly energize high current door openers
(absolute maximum is 14 V at 50 mA).
When using a door control relay, always place a
suppression diode (e.g. a 1N4001) across the relay
coil.
Status LED indications
See Figure 1.
Connected to ATS control panel or access control panel
Green / red
(disarm / arm)
Green: when all areas assigned to the RAS alarm
group are disarmed or when screensaver is active.
Flashing green when running on battery (mains
power off) or during unlock time when area
disarmed.
Red: if all areas assigned to the RAS alarm group
are armed. Flashing red during unlock time when
area armed.
LED off: if at least one and less than all areas
assigned to the RAS alarm group are armed.
Yellow (ready)
Active when all zones in areas assigned to the RAS
are normal (or active if RAS configured as
ATS1156).
Red (alarm)
Flashing when any areas assigned to the RAS is in
alarm state.
Connected to a Wiegand or Magnetic Stripe interface
Green / red
Green: On when yellow wire is at 0 V.
Red: On when brown wire is at 0 V.
Yellow: On when yellow AND brown wire at 0 V.
LED off: When yellow and brown wire are between
5 and 14 V.

Note:
In offline mode, the TERM switch (DIP switch 5) must be
Off (up). DIP switches 1 to 4 are not used in offline mode.
