10.2.3 Fault indications
Siemens Building Technologies
Fire Safety & Security Products
You can see faults in the VIS3I-328 in four ways:
Alarms
Error Message received on the Visilynx 3 keyboard
Indicator LEDs
The system did not function as expected.
Alarms
Alarms are generated by a variety of sources in the CCTV system. Depending on
the installation, they are mostly fed to the VIS3I-328, where their actions are
determined by the software configuration file. However, in larger installations, some
alarms (e.g. rack frame power failure) may be wired directly to an integrated control
room.
If a data log device is fitted and configured (this may be a printer with an RS232
interface connected to one of the rear panel serial ports), all alarm events can be
read from the data log printout. These events include operator actions taken in
response to alarms, as well as the alarms themselves.
If a printer is not available, the VisiPC software may be used to retrieve the last
2000 alarm and action events, using the Show Log button on the Alarm List tab of
the Visilynx (Tester and Simulator) sub-program.
Alarms may be individually enabled for handling by the Visilynx 3 keyboards.
Keyboard error messages
A number of error messages can appear on the Visilynx 3 Keyboard. The error
messages are defined in the Visilynx 3 Keyboard User Manual.
Indicator LEDs
See chapter 6.5 Front panel indicators.
System malfunction
The operator may observe that the system did not respond as expected to a
command. These observations should be logged as an aid to the system fault-
finding process.
