Alarm Relays:

There are three alarm-circuit connectors on the alarm relays block

(under RELAY OUTPUTS) for making connections to internal alarm relay contacts. Each provides a set of Form C contacts for each type of alarm. Each has both normally open and normally closed contact connections. The contact connections are indicated by diagrams on the rear panel. They are capable of switching up to 3 ampers at 250 V AC into a resistive load (Figure 2-6).

The connectors are:

Threshold Alarm 1: • Can be configured as high (actuates when concentration is above threshold), or low (actuates when concentration is below thresh old).

Can be configured as fail-safe or non-fail-safe.

Can be configured as latching or nonlatching.

Can be configured out (defeated).
