Prisma II Redundancy Interface Panel
The Prisma II Redundancy Interface Panel is an accessory to the Prisma II platform.
It is intended to be used with the master-slave feature and the contact closure alarm
feature of the Prisma II platform.
The Prisma II Redundancy Interface Panel serves as an extension to the two DB-37
connectors labeled ALARM IN and ALARM OUT on the connector interface panel of
the chassis. The terminals on the redundancy interface panel are extensions of pins
on the ALARMS OUT and ALARMS IN connectors on the chassis.
Note: This module takes up two slots in the Prisma II chassis. For purposes of
redundancy wiring, the module is identified with the higher-numbered slot. For
example, if the module occupies slots 6 and 7 (module ejector lever at slot 6), its
ALARM IN and ALARM OUT connections are made at slot 7, and the pins for slot 6
are not used.
