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.
