USER LEVEL
The system offers three user levels and, depending on these, various options are available.
The three levels are as follows:
1. OPERATOR level (O)
2. MAINTENANCE level (M)
3. ENGINEER level (E)
Once logged in with a certain level, a letter in the top right side of the screen will inform
about the level chosen, as follows: “O” for Operator. “M” for Maintenance and “E” for Engineer.
If the user is not logged in, the allowed operations are as per Operator level, without permit-
ting to do the “ACK” of the events.
The user passwords can be created and/modified only by the PC configuration software.
TEST/MAINTENANCE
This state is meant for testing and maintenance purpose. This testing function requires an
operation sequence and can be activated for each detector being connected. A user with
the OPERATOR or MAINTENANCE level cannot put under TEST/MAINTENANCE more than
50% of the system’s channels and outputs.
EXCEPTION: In case the system just includes one channel only, it will be possible to put that
channel under test. The same principle applies in the case when just one single output is
defined. That output can be put under test.
The signals from channels under TEST will be displayed but will not be considered, in the
way that no alarm will be triggered even though the alarm thresholds are being exceeded.
In the same way, the relays under TEST will not be activated, even if an alarm event associa-
ted is taking place while the relay is in TEST/MAINTENANCE mode.
UNSET
The state is useful for virtually excluding single detectors or parts of the system, without
physically interrupting the connection. The UNSET condition may be activated for each
channel or part of the system.
In the same way as for TEST/MAINTENANCE mode, a user with OPERATOR or MAINTENANCE
level cannot UNSET more than 50% of the system’s channels and relays. The only exception
is the ENGINEER level, which may UNSET the whole system if necessary.
EMERGENCY
This is a particular malfunction status that can occur for the following two reasons:
³
Malfunctioning of the Vdc power supply of the gas control unit
