Optional Network Connection
Linear’s AM-3, AE-1000, & AE-2000 Access Control Systems can
be connected together in a network. A network will allow sharing
programming and user information between the systems. Program each
unit to a different network Node Address.
Network wiring conforms to 3-wire RS-485 electrical specifi cations. Units
connected in the network can be wired using one unit as a “hub” or by
wiring from one unit to the next in “daisy-chain” fashion. See the fi gures
for wiring options.
• Use Belden 9925 or Carol C0600 shielded cable or equivalent.
Maximum wire run distance is 4000 feet.
✦ NOTE: Be sure to connect the cable’s shield to one of the GND
terminals.
Home-run Network
1. Mount and install the units for the network.
2. Choose one unit to be the Network Master. Usually this would be a
centrally located or “main” unit.
3. Route 3-conductor shielded cable from the Master unit to one of
the other units. Repeat this step to connect the Master unit to each
of the other units.
4. Connect the 3-conductor cable to each unit’s NETWORK
terminals.
Daisy-chain Network
1. Mount and install the units for the network.
2. Route 3-conductor shielded cable from one unit to the next unit
until there is cabling run to all of the units.
3. Connect the 3-conductor cable to each unit’s NETWORK
terminals.
