Chapter 3 Hardware Overview

1Use a connector to connect wires of the correct gauge to the sensor’s signal output pins. See Chapter 46 on page 333 for the wire specifications. Check the sensor’s documentation to identify its two signal output pins.

2Connect these two wires to any one of the following pairs of signal input pins on the Switch’s Signal connector--(4,5) (6,7) (8,9) (10,11). The pin numbers run from the right side of the connector to the left.

2a Connect each of the sensor’s two signal output wires to the Signal connector by depressing the spring clip corresponding to the pin you are connecting to.

2b Insert the wire and release the spring clip.

2c Repeat the process for the sensor’s other signal output wire. A total of four sensors may be connected to the Signal connector in this way using the remaining signal input pins.

3Insert the alarm connector into the Signal slot. Figure 16 Connecting a Sensor to the Signal Slot

4To connect an output devicel, repeat the previous steps but this time connect to either pins (1,2) or (2,3) on the Signal connector.

You can also daisy-chain the external alarm to another ZyXEL Switch which supports the external alarm feature. If daisy-chaining to a ZyXEL switch that is a different model, check your switch’s documentation for the correct pin assignments.

1Use wires of the correct gauge to connect either of the signal output pin pairs (1-normal close, 2- common) or (2-common, 3-normal open) on the Signal connector to the input signal pin pairs of an Signal connector on another ZyXEL Switch.
