Installation Instructions
Introduction
The IMS-4000 Dry Contact Bridge allows you to connect
a dry contact alarm from any device to your IMS-4000
Host or Node. The Dry Contact Bridge is compatible
with Normally Open and Normally Closed contacts. The
electrical connection between the sensor and IMS-4000
is made via RJ-45 patch cable (not included). The sensor
may be mounted either on a wall or rest on the floor.
Package Contents

Wiring the Contact
Connect your alarm contact to the terminal block labeled Input. Insert
the slot and tighten the screw. The slide switch selects between Normally Open (NO) and Normally
Closed NC) dry contacts. Place the switch in the appropriate position for the alarm contact you are
monitoring.
Cabling
The Dry Contact Bridge connects to the IMS-4000 Host or Node via an RJ-45 cable (e.g. CAT5
cable). The connection from the sensor to the Host or Node 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 Host or Node environment
input.
