Requirements

The CPX-1000 includes an Alarm board in the summary alarm panel at the top of the shelf. This Alarm board continuously monitors various internal system operating parameters and reports alarms (if failures are detected). Dry Form-A closures1 are provided for critical, major, and minor alarm connections to external local alarm surveillance equipment.

The closure specifications are:

Rated resistive load: 20 Ohms (typical) @ 50 mA, 5 Ohms (typical) @ 100 mA

Rated inductive load: not applicable

Operating voltage: 100 VDC/VAC (350 VDC or peak ac for 100 ms transients)

Continuous load: 250 mA dc, 150 mA ac

￿Minimum load: 10 A at 10mVDC

Critical alarm closure is normallyµ closed. Major and minor closures are normally open.
