Rising alarms required where there is normally no gas.
Falling alarms required where gas should normally be
present (e.g. oxygen).
Level at which the relay will activate.
Level at which the Level 1 relay will reset. Allows hysteresis
for applications such as ventilation control where the fan
should continue to run until the gas reaches a low level.
Latched means that in an alarm state, the relay will stay
active when the Accept/Reset button is pressed, and will
only reset when the alarm or fault has cleared and the
Accept/Reset key is pressed again.
Non-latched means that the relay will stay active when the
Accept/Reset key is pressed, but will reset automatically
when the alarm has cleared.
Latch-accept means that in an alarm condition the relay
will reset when the Accept/Reset button is pressed.
De-energised means that the relay coil is not energised in
a non-alarm state (normally de-energised).
Energised means that the relay coil is energised in a non-
alarm state (normally energised or ‘fail-safe’)
Visible means that an alarm will trigger the alarm LED
bar, internal sounder, external audible visual alarms, and
display the alarm message.
Hidden means that an alarm will only cause the alarm
icon
in the channel display to show. No other audible
or visual alarms will activate (used for ventilation control
applications)
A similar menu is available for Level 2 alarm relays, with the exception that the 'Off Threshold' and 'Indication' options are not
available.
