Cabling
The Dry Contact Bridge connects to the IMS-1000 via an RJ-45 cable (e.g. CAT5 cable). The
connection from the sensor to the IMS-1000 can utilize your existing network wiring infrastructure.
For example, the sensor may be installed in another room or another floor. Connect the bridge to
your structured wiring network via an RJ-45 jack. At the other end, connect a patch cable from
your structured wiring patch panel directly to the IMS-1000 environment input.
