NOTE

MCS�11 systems allow 128 station addresses (RSS). The polling system

operates on a time level basis. The station alarms are polled first. If no

station alarms are present, the poll goes to the next address. If there is a

station alarm, the poll reverts to the lower level and scans the detail

alarms. For this to work, the rack alarm from each rack must be wired to

the rack with the station scanner turned on and addressed. All other

racks must have the RSS address turned off.

2. Wire rack alarm audio (P102�51) to applicable station 1-16 alarm input on AE�35R Fault

Alarm Interface or station 17�32 alarm input on AE�78R Station Control Monitor via a

single wire between wirewrap adapters installed in J101 and J102 on digital shelf back�

plane. Refer to the typical connection scheme given in step 1.
