Mounting the unit
The RAS cover is hinged at the bottom. To open, grasp the
cover at the sides or the top and pull gently
— the cover will
swing down on its pins. The cover may be fully removed by
gently prising one of the pins away from the body of the RAS
and pulling.
A lock (Figure 2, item 5) holds the metal mounting plate at the
rear. Remove the mounting plate before installation. To do so,
press and hold the plastic lock (Figure 2, item 5), at the same
time slide the mounting plate down and pull its bottom away
from the body of the keypad.
Note:
Use a flat screwdriver to press the mount lock (Figure 5,
item 2) and slide the keypad up (item 3) to unmount the
keypad when it is mounted on the mounting surface. See
Figure 5, item C.
To install the keypad:
1. Put the plastic pry-off insert (Figure 5, item 1) into the slot
in the metal mounting plate as shown in Figure 5, item A.
2. Mark the screw positions on the mounting surface using
the metal mounting plate, and drill the holes.
3. Attach the metal mounting plate together with the pry-off
insert to mounting surface using the screws provided. See
Figure 5, item B.
4. Connect the shield of the data cable to one of the
mounting plate screws (see Figure 6 for example). If rear
cable entry is used (through the mounting plate), cut
a hole in the mounting surface for cable access.
5. Set the RAS address using DIP switches 1 through 4 (see
“RAS DIP switch settings” below). Set the bus termination
switch (DIP switch 5), if required. Terminate the bus
cabling.
WARNING:
All power should be turned off to the control
panel before wiring the RAS.
6. Insert plastic cable entry blanking plugs (provided) into the
rear of the RAS to blank any unused cable entry channels.
7. Place the RAS onto the mounting plate and lock in place
by moving the unit down by about 8 mm (0.315 in.)

Connecting control panel to keypad
Refer to the ATS control panel installation guide for
instructions.
Tamper switch
See figure 2.
The rear tamper switch must be sealed for the system to work
correctly. The tamper switch is sealed by mounting the RAS
onto the mounting plate, and then moving it to the locked
position. In operation, the LCD display will show
“RAS Tamper”
when not sealed.
RAS DIP switch settings
See figure 3.
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.
•
TERM switch: 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.
•
RAS address: Set the RAS address using switches 1 to 4.
Connections
See figure 4.
•
+13.8 VDC: 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 ft.) Otherwise the RAS can be powered by
AUX PWR from a DGP, or by an auxiliary power supply.
•
D+/D−: D+ is the data positive connection and D− is the
data negative connection of the data bus.
The RAS is connected to the ATS panel via the RS485 data
bus, up to 1.2 km from the control panel or the four-door
controller DGP. It is recommended to use two-pair twisted,
shielded data cable (WCAT 52/54). The shield of any bus
cable must be connected to system ground at one end only.
The ATS111x-N 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 jointed to provide continuity of
data cable shield.
•
RTE: An RTE button (normally open, momentary push-
button switch) can be connected across the
“IN” and “0 V”
terminals (see figure 4). When pressed, the button
controls the request to exit function to the panel.
•
IN: A request to exit button (normally open, momentary
push-button switch) can be connected across
“IN” and “−”.
When pressed, this button controls the request to exit
function.
