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.

wiring the Contact
Connect your alarm contact to the terminal block labeled Input. Insert 1/2" stripped bare wire into 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.
Caution: The IMS sensors are not TCP/IP devices and therefore should not be connected directly to any
wiring infrastructure that is connected to network equipment such as a hub, router, or switch. Sensors use
RJ-45 plugs and cables similar to those used with Ethernet devices.
