8 CA824 Installation manual
REMOVING MODULES FROM THE SYSTEM
The following has to be executed in case of physical removal of the module from the system:
The respective module can be removed from the list of modules by executing the Remove command at
address 8.0.xx.5., where xx is the module number in the device list. All adjustments set for a module,
after a Remove function, will be retained. Factory settings, however, will be preserved in the device itself.
Following this procedure, the device can be connected to another system.
A Remove procedure must be performed fore a faulty device, designated to be removed, after which the
new module should be connected and function 8.1. Add hardware carried out. Thus, the new device will
have the same settings as the old one.
DISABLING SYSTEM MODULES
This is done where a module has to remain physically connected to the system, but will not be in use:
1. 1.
Issuing a command at address 8.0.xx.3 can disable the respective module. Disable, where xx is
the number of the module in the list of devices. The settings and the singular number of the module,
subject to this function, will be retained, but all communications with it will be terminated.
2. 1.
Where necessary, the module can again be integrated with the regular performance of the sys-
tem by issuing a command at address 8.0.xx.4. Enable, where xx is the number of the module in the list
of devices. After this function is executed, communication with it the will be renewed.
This can be done at address 8.1. Add hardware in engineer programming mode. This mode is used
when the network is extended to include new modules or when a faulty module is being replaced. The
new module must have been connected beforehand to the System bus.
Upon starting a PnP procedure, the principle system module passes an identification command to the
bus modules for new devices. This procedure takes 20 seconds and concludes when a list of bus
related devices is compiled. This list can be viewed at address 8.0. in engineer programming mode.
If positioned over a specific module, the display will show its singular number and the module number in
the list of bus devices.
CA824 ALARM SYSTEM CHARACTERISTICS
CA824 alarm system consists of CA824 control panel and up to 15 additional expander modules. Con-
nection between modules is four wire common bus based on RS485.
Expander modules list:
- LCD824 keyboard
- LED816 keyboard
- MRI4/8 zone expander module
- MRI8 programmable output expander module
- DIO32 dynamic indication module
An inteligent PnP procedure is implemented which allows easy configuring the system.
Programming of system parameters is possible from LCD824 in the system, service LCD824 or through
telephone line.
Maximium number of zones 24 fully programmable zones
Zone programming 10 types of zones and 7 parameters
Maximum programmable outputs 16
Programmable outputs programming 7 groups of events in the system
Maximum number of areas 8 fully independent
Maximum number of users in the system 31 + 1 M 1 Engineer
Event LOG 256 events recorded with date and time of
occurence
Digital communicator built-in CA824 control panel
