ALARMS IN and ALARMS OUT Connectors
Every Prisma II Standard and II XD chassis provides connectors for external alarms
to and from each module slot. These alarm connectors are located on the chassis
connector panel and are labeled
ALARMS IN
and
ALARMS OUT
.
For detailed information on
ALARM IN
and
ALARM OUT
connectors, see the
Prisma II Chassis Installation and Operation Guide
, part number 713375 or the
Prisma
II™ XD Platform System Guide
, part number 4021339.
When a critical alarm occurs in a Master module, the Master turns off and the Slave
(redundant module) is enabled. To make this happen, the pin representing the
Master module slot in the
ALARM OUT
connector must be externally wired to the
pin representing the Slave module slot in the
ALARM IN
connector. After wiring
these contacts, take care to ensure that the Master and Slave modules are not moved
to other slots. Otherwise, the
ALARM IN
and
ALARM OUT
connectors will need to
be rewired to the appropriate pins.
Note:
Any device configured as Single or Master ignores its
ALARM IN
contacts.
To verify proper wiring and redundant configuration, simply unplug the Master
module and observe that the Slave module turns on.
