Product Guide
AT -BB -IN
RF input unit
Overview
The AT -BB -IN Input Unit provides a control interface
between a lighting system and external devices such as:
Button/switch plates
Security systems
AV equipment
The unit features seven Volt- free switch inputs that can be
activated by the contact closure of push-buttons, switches,
or relays.
Activating an input causes the unit to transmit a RF control
message to other devices, triggering various actions such
as recalling a scene, raising/lowering light levels, turning
override on/off, starting and stopping sequences, etc.
The integral RF transceiver allows wireless communication
with other An -10® compatible products. All functionality is
fully programmable using an infrared handset (e.g. the
UHS4 or UNLCDHS) or PC control software.
The unit is powered either by the internal battery or via an
external 12Vdc supply.

Infrared Receiver (IR)
Allows the unit to receive programming commands from an
IR Handset (e.g. the UHS4) when IR Receive mode is
activated (see Config Button and Status LEDs below).
Config Button
Press this to put the unit into IR Receive mode, enabling it
to receive programming commands from an IR Handset.
Status LEDs
These flash R ed and/or G reen to indicate the following:
IR Receive mode active
at 1 second intervals
Valid setting received
Invalid setting received
Software reset received
Factory reset received
Battery (type CR2477)
Provides power to the unit if an external supply is not used.
Optional 12Vdc Supply Terminal
To power the unit from an external supply, connect the
supply to this terminal ensuring correct polarity. Refer to
Technical Data on page 8 for power supply specification.
Plug -in RJ45 lead and socket
A short 8 core flat cable with plug that is supplied with each
unit, used to connect the inputs to external devices.

Installation
The AT-BB-IN Input Unit can either be mounted to any
suitable solid surface or concealed inside a backbox.
Surface Mounting Method
Fit the two snap-on mounting brackets on the back side of
the unit as shown in opposite.
Use the holes in the mounting brackets to affix the unit to a
wall or other solid surface using suitable screw fixings.
Backbox Mounting Method
For unsecured fixing, the unit can be simply placed inside
a UK or European backbox (without fitting the snap-on
mounting brackets). This enables a proprietary switch
plate to be connected and screwed to the backbox.
Alternatively, for secured fixing, fit the two snap-on
mounting brackets on the front side of the unit as shown
opposite. The unit can then be secured to the backbox
using suitable fixing screws (up to M3.5).
NOTE: The mounting bracket holes are spaced to suit
either a UK (60.3mm pitch) or European (60mm pitch)
backbox.
CAUTION: Do not over tighten the fixing screws as
this may cause the brackets to split.

Electrical connection
Connections to the AT-BB-IN Input Unit are made via the
RJ45 lead supplied. The lead has 8 wires, comprising 7
switch inputs plus a common connection (see below).
Connect the lead wires to suitable push-buttons or switches
as required (see wiring examples on page 3).
Each input has two possible states:
• Inactive when the input is unconnected
(i.e. open circuit), and
• Active when the input is connected to common,
(i.e. during button or switch closure).
Each input can be configured (using the Switch Type
parameter) for use with either momentary or latching type
buttons and switches.
• Momentary operation is the default, used for normally-
open push-buttons or centre-retractive type switches.
• Latching operation is typically used for toggle type
switches that remain in either a closed or open state.
IMPORTANT NOTE: Latching Mode is not suited to battery
operation due to the continuous current drain while a switch
is closed. An external 12V power supply must, therefore,
be connected if Latching Mode is used.
