I. INTRODUCTION
On-Q/Legrand offers an ALC Enhanced Branch Hub, PN
364736-01, -02 and -03 (see Figure 1) which extends
the wiring distances of ALC branches up to 1000
additional feet from a lighting controller. The Hub
incorporates active electronics that selectively
recondition weakened communication signals on an ALC
two-wire communications branch. The Hub supports
direct wiring of ALC switches to a centralized connection
location providing a structured ALC lighting system
installation. A direct wiring methodology is conducive to
testing and efficient isolation of faults when they occur.
The Hub acts as a conduit to pass ALC communications
between all connected switches and a lighting controller
(see Figure 2). Each ALC Enhanced Branch Hub
provides a DIP switch at each ALC switch connection
point to allow efficient isolation of individual lighting
controls from the ALC communication branch. A single
category cable may provide ALC communications and
12 VDC, 100mA power to each Hub. Each ALC
Enhanced Branch Hub is installed in a Hide-A-Port outlet
(included) for a clean professional installation and easy
accessibility.
II. DESCRIPTION
The ALC Enhanced Branch Hub provides connection
points for up to 9 ALC Dimmers, Relay Switches, Scene
Switches, Program Switches or I/O Modules, (see
Figure 1). All connection points consist of 110 style IDC
connectors for connection of category 3, 5 or 5E cable.
Connection Points 1 thru 7 provide connections for ALC
Auxiliary Switches to support 3-way dimming and
switching applications (see Figure 3). Connection Point
8 is provided for connection of an ALC Scene Switch,
Program Switch or an ALC Dimmer or Relay Switch
where multi-way local control is not required. Connection
Point 9 provides connections for up to 3 ALC Auxiliary
switches for 3, 4 or 5-way dimming or switching
applications (see Figure 4).

III. INSTALLATION
Note: The total cumulative length of all cables
connecting ALC Dimmers, Relay Switches, Scene
Switches, Program Switches and I/O Modules to the
ALC Enhanced Branch Hub should not exceed 500
feet (see Figure 5). Connection Point 10 provides
connections for a single category 3, 5 or 5E cable
that is homerun directly to the lighting controller.
Connection Point 10 provides additional
connections for cascading additional Hubs. The
maximum cable distance between the ALC
Enhanced Branch Hub and the lighting controller
should not exceed 1000 ft. Up to four (4) Hubs may
be connected to each controller ALC branch. The
wiring distance of each Hub from the controller
should not exceed 1000 ft. If ALC switches are
connected directly in parallel with the Hub to the
controller, the total cumulative branch wiring length
should not exceed 500 ft. (see Figure 6).

The ALC Enhanced Branch Hub installs within an 8-
Port Hide-A-Port outlet which mounts directly to a two-
gang electrical box or an On-Q Low Voltage Bracket
(see Figures 7 and 8). Upon powering up the ALC
Enhanced Branch Hub, the integral green Power LED
will illuminate.
Note: If the green Power LED does not illuminate
check the 12 VDC and Ground (GND) power
connections. Ensure that correct voltage polarity
is maintained when connecting 12 VDC power to
the ALC Enhanced Branch Hub. Failure to maintain
correct polarity may result in damage to the ALC
Enhanced Branch Hub.
