External Alarms Connections
Master/Slave Operation
All Prisma II modules ship from the factory configured as a master. The
LCI, TNCS software, or the ICIM can be used to reconfigure a module as
a slave or as redundant (slave).
The Chassis allows for local hard-wired redundancy by using the ALARM
IN and ALARM OUT connectors. A pair of modules can be configured so
that if the master fails, the slave takes over by using the ALARM IN and
ALARM OUT connectors
ALARM IN and ALARM OUT Connectors
The Prisma II Chassis provides two connectors for external alarms to and
from each module slot. These alarm connectors are located in two 37-pin
D-connectors (DB-37) and are labeled ALARM IN and ALARM OUT.
• NOTE: Master Slave feature requires Redundancy Interface Panel (RIP). The RIP serves
as an extension to the two DB-37 connectors labeled ALARM IN and ALARM OUT – see
IO Guide for further details
