OVERVIEW This section describes the SPA with HART Alarm option for the OCX 8800.

DESCRIPTION The Moore Industries SPA with HART Alarm, Figure B-1, is a 4-wire (line or

mains powered), site-programmable, digital process alarm. It connects to a

standard HART field device, and provides up to four, fully configurable,

contact-closure outputs based on readings of the HART digital data. The four

OCX 8800 alarm outputs recognized by the SPA are Low O2, High COe,

Calibration Status, and OCX Unit Failure.
