Figure 19.2 – Diagram of the Click 222

Connections

The faceplate of the Click 222 has three RJ-11 jacks, which provide the following three in-

dependent serial connections:

˽

Topmost jack – control bridge

˽

Middle jack – dedicated communications for sensor 2 detection calls

˽

Lowest jack – dedicated communications for sensor 1 detection calls

The back of the Click 222 features a 5-position connector that plugs into a T-bus connector

and provides power and RS-485 communication to the device. It also passes RS-485 com-

munication from the module to all other devices on the T-bus.

The bottom of the Click 222 has three pluggable screw terminal blocks with four terminals

each, for a total of twelve connections. These terminals are used for wiring in the cable from

the sensor. The terminals have four different RS-485 connections, each consisting of a +485

and a -485 terminal; two of these connections are for detection calls and two for the con-

trol bridge, allowing two sensors to be wired in to each Click 222. This will be explained in

greater detail in the Installation section of this chapter.
