Common Service Modules
The Common Service Module (CSM) is typically located in the lower right cell of
the Annunciator System in card slot 1. It is used to provide common alarm
outputs, perform flashing per selectable ISA Sequences and coordinate the
pushbutton controls. One version CSM includes the Time Stamping of Alarms or
Sequential Events Recorder (SER). The CSM has four common alarm outputs
(2 standard and 2 optional) with relay operation configured via Software. All
Annunciator software configuration is performed through the CSM serial port,
accessible from the front of unit. The CSM module can be configured via
jumpers for Form A or B Relay Contacts.
