Alliance Arming Station
Installation Instructions

Tamper switch
The back tamper switch (
on page 1) must be secured to
work correctly. Make sure that the tamper switch remains
depressed when the unit is mounted. If the unit is tampered with,
the tamper switch should spring open.
In operation, the LCD screen will show
RAS tamper
when not
sealed.
DIP switch settings
Use the DIP switches located on the back of the unit (
page 1) to set the RAS address and the system bus termination
condition (
).
Figure 3. DIP switches
RAS address switches
Use switches 1 to 4 to set the RAS address (as well as the reader
address for the AL-1116).
shows the DIP switch settings
for the system RAS addresses. Switch toggles are indicated as
black. For example, RAS 1 is Off, Off, Off, Off.

Term switch
Use switch 5 (
) to set the system bus termination to
ON
,
if needed.
There must be no more than two Term switches or links set to
ON
for any system bus. Refer to the control panel installation manual
for details about the Term switches or links.
Wiring
Use the terminal block (
) on the back of the unit to wire
the COMMS system bus connection.
Figure 5. Terminal block
System bus connection (D+ and D-)
Connect the unit to the Alliance panel via the RS-485 system
bus. You can connect the unit up to 5,000 ft. (1.5 km) from the
control panel or 4 door/elevator controller DGP. We recommend
you use a Beldon 8723 twisted-pair, shielded data cable.
The shield of any system bus cable must be connected to system
ground at one end only. This unit does not provide an Earth
connection for this purpose. If you daisy-chain the system bus to
the unit, ensure that the shield of the cable is jointed to provide
continuity of the data cable shield.
D+.
Data positive connection of the system bus.
D-.
Data negative connection of the system bus.
Power supply (+12 and 0V)
You can power the unit by the control panel or by a separate
power supply. If you use the control panel’s + and - power, the
distance between the unit and the control panel must not exceed
328 ft. (100 m).
To power the unit by the AUX PWR from a DGP, or by an auxil-
iary power source, do the following:
1.
Connect the + of the local power supply to the +12 terminal
of the unit (
). Do not connect the + power of the
system bus to the unit.
2.
Connect the - of the local power supply to the 0V terminal
of the unit and to the - power of the system bus.
3.
For optimal performance, adjust the power supply to 13.8
VDC.
