AL-111X Arming Station
Connections
A terminal block on the back of the RAS (see Figure 1) is used for the COMMS (System BUS) connection.
System BUS Connection (D+ and D-)
The RAS is connected to the Alliance panel via the RS-485 System BUS, up to 5,000 feet (1.5 km) from the control panel
or the four-door controller DGP. It is recommended to use a 2-pair twisted, shielded data cable (Beldon 8723).
or the four-door controller DGP. It is recommended to use a 2-pair twisted, shielded data cable (Beldon 8723).
The shield of any System BUS cable must be connected to system ground at one end only. The AL-111X RAS is not
provided with an Earth connection for this purpose. If the System BUS is “daisy-chained” to the RAS, ensure that the shield
of the cable is jointed to provide continuity of data cable shield.

of the cable is jointed to provide continuity of data cable shield.
•
D+ is the data positive connection of the System BUS.
•
D- is the data negative connection of the System BUS.
Power Supply (+12 and 0V)
Powered by the control panel
The RAS can be powered using the System BUS “+” and “-” power from the control panel, if the distance between the
RAS and the control panel does not exceed 328 feet (100 m).
RAS and the control panel does not exceed 328 feet (100 m).
Powered by separate power supply
The RAS can be powered by AUX PWR from a DGP, or by an auxiliary power supply.
When using an auxiliary power supply:
•
Connect the “+” of the local power supply to the “+12” terminal of the RAS. Do not connect the “+” power
of the System BUS to the RAS.
of the System BUS to the RAS.
•
Connect the “-” of the local power supply to the “0V” terminal of the RAS and to the “-” power of the
System BUS.
System BUS.
•
For optimal performance, adjust the power supply to 13.8 VDC.

Egress Contol and Open Collector (IN and OUT)
Terminals IN and OUT are optionally used for egress control and door relay operation:
•
IN - An egress botton (normally open, momentary push-button switch) can be connected across the “IN” and “0V”
terminals (see Figure 5). When pressed, the button controls the request-to-exit function to the panel.
•
OUT - Open collector output must be assigned with a number according to type of control panel. Use the first output
control assigned to the RAS. Refer to the control panel programming manual for details.
