Partitioned or Single System
During installation, the Installer can configure the system as a partitioned
system or as a single system.
In a single system, the control unit has one full set level (security level A) and
three part set security levels (levels B, C and D). Users can set only one level
at a time. Level A sets the whole system. Levels B, C and D set parts of the
system. The Installer allocates zones to levels, but all keypads operate the
entire system. There is only one sounder output for the whole system, and
you can use a loud-speaker for setting tones and local alarms. All users
belong to the whole system.
When working as a partitioned system, the control unit effectively provides
four smaller alarm systems. Within a partitioned system:
• Each partition can be set, unset or in alarm independently of the others.
• You can assign individual keypads to one or more partitions. The keypads
can only set or unset the partitions to which they are assigned.
• Each partition can have its own Bell and Strobe Set output.
• Zones can be assigned to more than one partition; for example, an entry
door zone may be shared by several companies using separate partitions.
You can set up the control unit as a single or partitioned system using
Command 98 (this will also restore the control unit to factory defaults).
For an overview of the programming steps required to set up a partitioned
system, see Chapter 4 in the Programming Guide.
User Control
The control unit provides 50 independent User access codes and a separate
Duress Code. Users can change these codes at any time but cannot use
them to program the system. During installation, the Installer can select
whether access codes use four or six digits.
