Chaining the EX5500 Controllers
In an area where the required LF coverage exceeds the capacity of one EX5500
Controller, you can extend the coverage by chaining several Exciters. For example, a
large entrance with two sets of double doors too wide for a single Exciter, might
require two Exciters chained together. EX5000, EX3210, EX2000B or EX4200 Exciters
can be chained to an EX5500 Controller.
Note
EX5500 Controllers cannot be chained to other EX5500 Controllers.
The system treats chained Exciters as a single device with a single ID. Transmissions
do not interfere with one another.
Each Exciter must be positioned to allow transmission range overlap between
neighboring Exciters. This ensures full coverage of the area.
Figure 7 shows 5 chained Exciters, their connections and the state of each Exciter
termination switch.

EX5500 Chain Connection
Up to 4 Exciters can be connected to the EX5500 in a chain, as follows:
1.
The first Exciter in the chain, directly connected to the LAN, is designated the
“Master”. Other Exciters are designated “Slave”.
EX5500 Controllers can act as either Master or Slave Exciters.
