LEAVING PROGRAMMING MODE

, and then
confirm by pressing the ENT key.
The system must be checked for open zones before leaving programming mode. This is necessary
because any 24-hour open zone would sound the alarm upon leaving programming mode.
If the sys-
tem siren is triggered, introduce a valid user code and then press the DISARM key to halt it.
To avoid this, go through the list of zones in menu 010, which are open or have a tampered self-protec-
tion circuit. Restore all zones, which may trigger off the alarm.
Physical and Logical Level of the System
The CA864-based security system should be considered as an entity operating at both the physical and
logical levels.
The physical level includes all modules and their resources (inputs and outputs). The restrictions at this
level relate to the number of modules that can be connected to the bus, i.e. up to 32. As to the resources
(inputs and outputs), there exist no restrictions at this level. This means that the modules actually con-
nected to the bus can provide inputs and outputs in a larger number than those maintained at the logical
level.
The logical level of the system includes zones and their types, their belonging to groups and others, the
programmable outputs together with their operational logic; user codes with all their settings, estab-
lished groups, etc. Generally, the logical level is the allocation of the resources available at the physical
level and the setting of the operation of the system as a security center.
Actually, zones and programmable outputs start operating only upon assignment of a logical number
and definition of the parameters of each one to be used. This is performed separately for each module
at the
8.0.x.x.0. Inputs config
address for the inputs and
8.0.x.x.1. Outputs config
for the outputs,
where x.x. denotes the shortcut address of the module. These addresses are inaccessible to modules
that have no resources at these addresses.
The restrictions for the zones are up to 64 logical numbers, while for programmable outputs they are up
to 48 logical numbers. Resources for modules that will not be used retain the logical number 00.
Procedure PnP for Identification of New Hardware
Each module of the set of the CA864 system has a unique number recorded in the manufacturing
process. It is with this number that the device will take part in the exchange on the bus. The number
consists of the serial number of the device plus a two-digit code corresponding to the module type.
The PnP procedure is used for switching on new modules connected to the bus in the logical structure
of the system. There exist two options for starting PnP:
-
automatically
upon power supply with Reset jumper installed. This option is used in the initial setting of
the network configuration. All modules need to have been connected in advance to the System Bus.
-
manually
from the
8.1. Add hardware
address in the mode of programming by the engineer. This
option is used when the network is expanded with new modules or a defective module is replaced. The
new module needs to have been connected in advance to the System Bus.
When the PnP procedure is started, the main module of the system sends a command to identify new
devices to the modules on the bus. The procedure takes 20 seconds and ends up with the compilation
of a list of devices on the bus. This list can be seen at the 8.0 address in the mode of programming by
the engineer.
When a specific module is selected, the screen will display its unique number and the number of the
module on the list of devices on the bus (hereinafter referred to as “the shortcut address of the module”).
In the further programming at the logical level of the system, module resources will be identified with
regard to the module on the basis of its shortcut address.
