When an alarm point in a zone set in test mode is tested, it is presented in the display as
a fire alarm but with the information "Test mode" added.
No outputs (sounders) will be activated except the fire door outputs. The test mode alarm
will be automatically reset after approx. 10 seconds.

Heavy Smoke Alarm / Heavy Heat Alarm
An analogue detector (sensor) can activate a heavy smoke / heat alarm for a higher alarm
level than the normal fire alarm level, i.e. a normal fire alarm is already activated by a
detector activating a heavy smoke / heat alarm. See FT128 Technical Manual for the
system.
Heavy smoke / heat alarm is to confirm heavy or increasing smoke / heat and can be used
for special actions, e.g. activation of smoke ventilation, and so on.
In Case of a Heavy Smoke / Heat Alarm, outputs programmed for heavy smoke / heat
alarm will be activated. General heavy smoke / heat alarm and individual alarm points /
zones.

Heavy smoke / heat alarm will be reset when the fire alarm is reset, see section 15

Alert Annunciation Alarm (AA Alarm)
When the AA function is enabled, indicated by the LED "Fire brigade tx delay", the
indications, actions etc. are similar to a normal fire alarm (see above) except that FT128
output for routing equipment (Fire Brigade TX) will not be activated directly. An AA alarm
is indicated by the LED "Fire Brigade TX delay" (L16).
The AA alarm has to be acknowledged within an acknowledgement time and reset within
an investigation time, otherwise the output(s) for routing equipment (Fire Brigade TX) will
be activated. See FT128 Technical / Programming manual for more information regarding
the AA function. Acknowledgement and reset of the AA alarm can be performed on an AA
unit 1736.

Co-Incidence Alarm (2-Address / -Zone Dependence)
The co-incidence alarm function is programmed via EBLWin for the alarm points / zones
in question.
When only one zone or one zone address (alarm point) is in alarm status
one two-zone dependent zone is in alarm status
and there is a Coincidence alarm presentation in the display. Note that LEDs "Fire" are not
indicating a co-incidence alarm.
The co-incidence alarm will be automatically reset after 5 minutes or via the "Reset" button.
See chapter "Alarm reset". Examples for Co-incidence alarm zone / address and zone
shown below:

If two or more two-unit dependent alarm points (zone - addresses) in the same zone are in alarm status at the same time,
normal fire alarms will be activated in FT128. See also FT128 Technical / Programming Manual.

If two or more two-zone dependent zones in the same group are in alarm status at the same time, normal fire alarms will be
activated in FT128. See also FT128 Technical / Programming Manual.
