4.3.4 Reset mode for level 1 alarms
The reset mode for an alarm specifies the way in which it is reset:
▪
Latching mode: when the cause of the alarm has disappeared, the alarm remains
activated until a manual action (RESET 2x) is performed on the control unit.
▪
Non-latching mode: when the cause of the alarm has disappeared, the alarm is
automatically reset and disappears.
Only the reset mode for the level 1 alarms can be configured. A level 2 alarm always needs
to be manually reset.
In manual reset mode, the U•H1 control unit can display an alarm message when the gas
concentration has already returned to under the alarm threshold.
This configuration element applies to all level-1 alarms.
4.3.5 'Siren' mode for level 1 alarms
The 'Siren' mode designates a specific behavior like that of the "Siren" output of the U•H1
control unit or its audible indicator: while the alarm is still active (the gas concentration is still
greater than the alarm threshold), it is possible to reset the actions on the relays.
This mode does not apply to level-2 alarms.
This configuration element applies to all level-1 alarms.
4.3.6 Channels information

Info menu
The 'Channels info' item allows you to view the status list of the input channels.
The possible states are as follows:
▪
Disabled: Even if a detector is connected to this channel, it will be ignored by the
central unit. No measurement or error status will be reported.
▪
Enabled: the measurement channel is active; the central unit reads the signal and
acts accordingly.
