Alarm Relays: The nine alarm-circuit connector pins connect to the internal alarm relay contacts. Each set of three pins provides one set of Form C relay contacts. Each relay has both normally open and normally closed contact connections. The contact connections are shown in Table 3-2. They are capable of switching up to 3 amperes at 250 V ac into a resistive load. The connectors are:

Threshold Alarm 1:

Can be configured as high (actuates when concentration is above threshold), or low (actuates when concentration is below threshold).

Can be configured as failsafe or non-failsafe.

Can be configured as latching or non-latching.

Can be configured out (defeated).

Threshold Alarm 2:

Can be configured as high (actuates when concentration is above threshold), or low (actuates when concentration is below threshold).

Can be configured as failsafe or non-failsafe.

Can be configured as latching or non-latching.

Can be configured out (defeated).

System Alarm:

Actuates when DC power supplied to circuits is unacceptable in one or more parameters. Permanently
