INTRODUCTION
The APR3-HUB2 is a
non-addressable module that
Hub and Bus Isolator
(APR3-HUB2)
(V1.0)
Instructions
APR3HUB2-EI01
If a hub’s output experiences trouble or tampering, the control panel
will generate a missing module trouble for every module connected
on that output.
extends and divides the control
panel’s bus into two completely
isolated bus outputs (two for each
connected APR3-HUB2). It extends
the combus/communication bus by
regenerating the signal between the
control panel and its modules.
Should one bus output experience
trouble or tampering, the other will
remain unaffected. The hub
monitors the signal between the
control panel and modules on each
output. If the hub detects a loss of
signal integrity it will cut off the
troubled output until proper
communication is reestablished.
INSTALLATION
Connecting the APR3-HUB2
Connect the APR3-HUB2’s four input terminals labelled
YEL to the corresponding terminals of the control panel as shown on the back
page (Figure 2 “Connecting the APR3-HUB2”).
Extending the Bus
The APR3-HUB2 has two independent bus output terminals (labeled “OUT”)
to connect system modules. From a hub, you can connect modules in a
serial or “daisy-chain” configuration up to a distance of 914m (3000ft) for
Digiplex panels and 76m (250ft) for a Spectra panel as shown on the back
page (Figure 2 “Connecting the APR3-HUB2”).
Each hub on the combus/communication bus requires the
connection of two power supplies (one for each bus output
terminal). Use either an external power supply such as the PS817 for Spectra or a supervised power supply such as the
DGP2-PS17 for Digiplex. In addition, each power supply requires
its own transformer. Alternate configurations may result in
improper operation or damage to the system.
The APR3-HUB2 is non-addressable, therefore you can connect an
unlimited amount of hubs to the combus/communication bus without
affecting the total number of modules supported by the control panel.
RED, BLK, GRN, and
Visual Feedback
The APR3-HUB2 has on-board LEDs to display activity status. These are:
WDG LED: Flashes to show proper hub operation.
ERROR LED: Flashes to show a network fault.
DATA LED: Flashes to show network communication
between modules to control panel.
Troubleshooting
In the event that LEDs display the following status:
WDG LED does not flash: Verify that the power supply for the input is
properly connected.
ERROR LED Flashes: Verify the following:
• Verify that the power supply for the output
is properly connected.
• Verify for wire shorts between the output’s
GRN and BLK wires.
• Verify for wire shorts of connected modules
on the affected output.
• Remove any relay, hardwired, or non busmodules connected on the output, as this
will affect communication.
SPECIFICATIONS
Power input: Typically 12-16Vdc
Current consumption: Typically 24mA. (50mA max)
Distance from panel: Digiplex (DGP-848/DGP-NE96):
18AWG = 914m (3000ft) or
22AWG = 305m (1000ft)
Spectra:
18AWG or 22AWG = 76m (250ft)
Distance of each output: Digiplex (DGP-848/DGP-NE96):
18AWG = 914m (3000ft) or
22AWG = 305m (1000ft)
Spectra:
18AWG or 22AWG = 76m (250ft)
Operating temperature: -20°C to 50°C (-4°F to 122°F)
Compatibility: Any Spectra or Digiplex (DGP-848, DGP-
NE96) control panel
Since the APR3-HUB2’s is non-addressable, the WinLoad
software will not recognize the APR3-HUB2. WinLoad will
recognize addressable modules connected to hubs throughout
the combus/communication bus.
