shown (e.g. a fault message), for priority order see section 3.4.2.2 Information Priority
Order page 19.
All outputs (for fire alarm) are reset, i.e. de-activated.
15.2.3
Single Reset with Automatic Disablement
Similar to "Single reset" but includes the encapsulation function.
Normally when an alarm point or zone having activated fire alarm is reset whilst still is in
alarm status, it will activate a new fire alarm within 20 seconds.
When "Single with automatic disablement" reset is performed, an alarm point or zone, still
in alarm status, will not only be reset but also disabled, i.e. it will not activate a new fire
alarm within 20 seconds. It has to be re-enabled via menu H2/B6 (see page 93) before it
can activate a new fire alarm. (This function, set via EBLWin, is a violation to AS7240-2
standard).
LED "Disablements" (L8) is indicating one or more disablements in the system.
When "All" or "Single" reset is used, "automatic disablement" (encapsulation function) can
be used by pressing "Reset" (P4) and approx. 0.1 sec. later also press "Alarms queued"
(P1) and hold them pressed for > 0.5 sec. The alarm point or the whole zone (conventional)
currently shown in the display will be reset and disabled.
15.3
Test Mode Alarm Reset
Test mode alarm is automatically reset after approx. 10 seconds.

Heavy Smoke / Heat Alarm Reset
If a heavy smoke / heat alarm has been activated, it will be reset at the same time as the

Alert Annunciation Alarm Reset
Regarding the function, see chapter "Alert Annunciation Alarm (AA Alarm) page 54 and
FT128 Technical / Programming manual, chapter "Alert Annunciation".

FT128. AA alarms will be reset all at a time.
Note: Reset via an AA unit (1736) is only possible during the investigation time and only
if the alarm is an AA alarm (not normal fire alarms). If more than one AA alarm is
activated, they will be reset all at the same time.
