Overview
The Network Bridge is used to extend the network where more
than 1000m/3200ft of cabling or more than 100 devices is required.
The BN-2-NA allows for extension of the network and connection
of multiple networks together; approximately 65,000 devices may
wire to one system. The network bridge ensures reliability of large
systems by isolating and containing any network cabling faults.
The Network Bridge has two operation modes. It can act as a simple
repeater or, it can act as a network bridge that allows for filtering of
messages and network traffic.
Features
Connect multiple iCAN networks
Enables networks to grow beyond 1000m/3200ft of cabling
Allows larger multi story applications to be installed and
commissioned floor by floor
Designed and manufactured to ISO9001:2000 standards
16 sequences, each with a maximum of 128 actions
Status LED’s show network activity

Requirements
Dimensions
Supply: 12 Vdc via the network
iCANnet connection: Screw terminals with
two part connectors, able to accept 16 AWG
(1.5mm2) stranded or solid wire
2-part aluminium housing.
Mounting: 6 holes for screw mounting or
Ty-wraps
Suitable for Eaton’s Cooper LC cable
Temperature Range:
32°F to 104°F (0°C - 40°C)
Humidity: 0% - 95% non-condensing
The BN-2-NA optically isolates the connected
network segments and does not pass power
through to the connected network segment.
Adequate power must be on both sides of
the BN-2-NA to power the devices along the
connected segments. It may be necessary
to add EXPS-15V power supplies to boost
available power when BN-2-NA devices are
added. One source controller or EXPS-15V
power supply is capable of powering 10
devices over a 1000 foot cable run. Ensure
power is adequate on both connected
network segments. When used in bridge
mode, ensure that the main bridge backbone
has adequate EXPS-15V supplies to power
the backbone network.

Sample System Topology
In Repeater mode, the BN-2-NA allows extension of the network an additional 3200 feet and 100 devices per repeater.
All messages are passed through all network segments without filtering.
In Bridge mode, the BN-2-NA connects a main bridge backbone to up to 250 network segments. Message filtering
will occur to allow for maximum network usage.
