Multi-station operation and redundancy
With Senstar 100 systems that include multiple CUs, you have a choice of setups:
•
alarm processing distributed between the CUs so that each CU is responsible
for specific functions or areas (This configuration is frequently used at large
facilities.)
•
complete system alarm processing performed on all CUs so that every CU is
capable of responding to any alarm situation
•
alarm processing performed on one CU while a second CU serves as a “hot
standby” backup (In this case, the primary CU has full control of the security
system; the backup CU assumes full control of the system, if the primary CU
goes off-line.)
All of the CUs are kept current on the status of the entire system, regardless of
how the alarm processing functions are setup in a multi-station Senstar 100
system. The Control Map Display feature of Senstar 100 lets the system supervisor
specify the maps that display on each CU. With four Map Display options
available, you can do the following functions with the maps:
•
post
- can be viewed by the operator, and alarms are presented to the
operator for processing
•
monitor
- can be viewed by the operator at this CU; alarms are presented for
processing elsewhere (i.e., the CU where the map is posted) (If the alarm is
not processed within a user-specified time limit, the alarm can be
automatically transferred for processing at the monitored location.)
•
conceal
- cannot ordinarily be viewed by the operator, and alarms associated
with the map are not presented to the operator (The map can be made
temporarily available if the operator selects the
Post All
function, and
becomes available automatically if the CU where the map is posted fails.)
•
restrict
- can never be viewed by the operator, and alarms associated with the
map are not presented to the operator (This function is used to isolate higher
security, or geographically separate areas from a CU station.)
If
Map Concealment
is enabled, in a typical two-CU system, the alarm processing
responsibilities are divided between the two CUs, according to the supervisor’s
Map Control definitions. If one of the CUs should go off-line, the other CU would
assume full control of the security system.
If
Map Concealment
is disabled, all maps and alarm processing responsibilities
are available on each CU.
There are numerous applications for multi-station Senstar 100 operation. Contact
