PSAX 4500 Alarm Module
Software Features
The PSAX 4500 Alarm module provides two connectors that allow for con-
nections with external facility sensor inputs (doors, temperature, and so on),
chassis alarm outputs (visible and audible), external device controls (cooling,
heating, doors, and so on), and audible alarm cutoff controls (see
Figure E-2). In addition, the CPU2 module generates trap messages that
reflect state changes of the PSAX 4500 Alarm module’s sensor inputs, control
outputs, and alarm cutoff control.
