Connecting modules in a cluster
Communication between modules within a cluster is accomplished using
SenseNET+.
A cluster consists of a minimum or standard display module and up to eight
detectors. The display module can be installed anywhere within the cluster.
Caution: A command display module cannot replace or substitute a minimum or
standard display module in a cluster configuration.
There are three types of cluster, as shown in the table below. Connections
depend on the type of cluster used.
Cluster type
Non-distributed
Distributed
Hybrid
Connecting a non-distributed cluster
Connect a non-distributed cluster (a minimum or standard display module and up
to four detector modules) using the supplied ribbon cable and the J3 and J5
connectors on the backplane PCB, as shown below.
In this installation type, the ribbon cable also distributes the power supply within
the cluster (see "Connecting the power supply" on page 26).

Note: End-of-line termination is not required for unused J3 and J5 connectors in
this cluster type.
ModuLaser Modular Aspirating Smoke Detector Installation Manual
Description
This cluster type consists of a minimum or standard display module and
up to four detector modules installed in the same location (next to each
other).
This cluster type consists of a minimum or standard display module and
up to eight detector modules, with each module installed in a different
location (not next to each other).
This cluster type consists of a minimum or standard display module and
up to eight detector modules. Some of the modules are installed in the
same location (non-distributed), others are distributed.
