Corbus wiring
The RED and BLK Corbus terminals are used to provide power while
YEL and GRN are used for data communications. The 4 Corbus terminals
of the alarm controller must be connected to the 4 Corbus terminals or
wires of each module.
The following conditions apply:
l
Corbus should be run with 18 to 22 AWG quad, two pair twisted
preferred.
l
The modules can be home run to the panel, connected in series or
can be T-tapped.
l
Do not use shielded wire for Corbus wiring.
Note:
Any module can be connected anywhere along the Corbus. Separate
wire runs for keypads, zone expanders etc. are not necessary.
Note:
No module can be more than 1000 ft / 305 m (in wire length) from
the panel.
Do not use shielded wire for Corbus wiring.
Figure 1-6 Corbus wiring
Module (A) is wired correctly as it is within 1000 ft / 305 m of the panel,
in wire distance. Module (B) is wired correctly as it is within 1000 ft / 305
m of the panel, in wire distance. Module (C) is NOT wired correctly as it
is farther than 1000 ft / 305 m from the panel. For models that require
more than 1000 ft / 305 m from the main panel, a HSM3204CX power
supply/Corbus extender can be used.
Current ratings
In order for the system to operate properly, the power output of the alarm
controller and power supply modules cannot be exceeded. Use the
following data to ensure that the available current is not exceeded.

AUX/
Corbus:
2 A. Subtract the listed rating for each keypad, expansion
module and accessory connected to AUX or Corbus. At least
100 mA must be reserved for the Corbus.
BELL:
700 mA continuous rating. 2 A. short term. Available only
with standby battery connected. DO NOT exceed the 700
mA load for UL/ULC or EN certified applications.

AUX1:
AUX2:
3 A. Subtract the listed rating for each keypad, expansion
module and accessory connected to AUX.
HSM3408
AUX:
500 mA. Continuous rating. Subtract for each device
connected. Subtract the total load on this terminal from the
alarm panel AUX/Corbus output.
HSM3204CX AUX/
Corbus:
2 A. Continuous rating. Subtract for each device connected.
HSM2208
AUX:
250 mA. Continuous rating. Subtract for each device
connected. Subtract the total load on this terminal from the
alarm panel AUX/Corbus output.
HSM2108
AUX:
100 mA. Subtract for each device connected. Subtract the
total load on this terminal from the panel AUX/Corbus
output.
Alarm Control Panel
AUX - 2000 mA available for devices connected to the AUX and PGM
terminals, and modules connected to Corbus terminals. At least 100mA
must be reserved for the Corbus.

Total (must not exceed 2 A)
For UL, ULC and Commercial Listed applications, the total standby and
alarm current cannot exceed 2 A.
Note:
For EN50131, UL, ULC and Commercial Listed applications, the
total standby and alarm current cannot exceed the values in Aux Loading
and Battery Selection for the applicable type of installation.
Capacitance limits
An increase in capacitance on the Corbus affects data transmission and
causes the system to slow down. Capacitance increases for every foot of
wire added to the Corbus. The capacitance rating of the wire used will
determine the maximum length of the Corbus.
