∙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 configured as failsafe and latching. Cannot be defeated. Actuates if self test fails.
