5.4.4 Important Message (Emergency Speech)
Important Message is a toggle action button. It will
normally self-clear after ~30 seconds of no action of
either a button press or PTT broadcast. The standard set
up is to require a second action to broadcast Emergency
Speech, i.e. to actively select Important Message then
begin broadcast with PTT.
If assigned to a standard button the associated indictor
has the following states:
Off
Important Message is not active
Slow flashing (0.5 Hz)
An Important Message is being broadcast on the
system
Solid
Important Message is active on the local panel
(may or not be broadcasting)
ote:
N
An important message broadcast is to all areas unless specified
as part of the unit ordering.
5.4.4.1 Combined Important Message and PTT
A combined PTT and Important Message button will
broadcast Emergency Speech while activated.
The indicator will follow the same pattern as for standard
PTT.
Warning:
Check regulatory requirements
regarding Emergency Speech broadcasts as
some require a two-step process to avoid
accidental activation.
5.4.5 Zone button
Zone buttons can be used to give the Hmi-5 access
panel increased speech broadcast flexibility by allowing
the pre-selection of broadcast zones before activation of
PTT.
Zone buttons have a timeout of ~6 seconds. If no PTT
or additional zone button activation occurs within this
time window, they all self-clear. Each button activation
resets the timeout counter.
Warning:
The default zoning of PTT and zone
buttons must be specified as part of unit
ordering.
If assigned to a standard button the associated indictor
has the following states:
Off
Associated Zone(s) are not active
Slow flashing (0.5 Hz)
Associated Zone(s) are being broadcast into by
the system
Fast flashing (5 Hz)
Associated Zone(s) are pre-selected by the local
panel (PTT not active)
Solid
Associated Zone(s) are selected by the local panel
(may or not be broadcasting)
5.4.6 Alarm activation
Alarm activation buttons can be set to activate any one
of Alarms 1 to 6. Alarms by default are all areas, but
fixed function zoned alarms are possible (see 6.4.6.1
Zoned alarms).
Typical associated indicator function:
Off
Associated Alarm is not active
Slow flashing (0.5 Hz)
Associated Alarm is active on the system but not
from the local access panel
Solid
Associated Alarm is active from the local access
panel
ote:
N
Alarm activation function within Sonix PA/GA is NOT a toggle
action, clearing the alarm requires activation of Alarm Cancel.
5.4.6.1 Zoned Alarms
Alarm activation function on the Sonix Hmi-5 are
usually All-Call, i.e. activates the alarm into all areas. It
is possible to change the default action to be a zoned
alarm
ote:
N
This is not recommended but if zoned alarm activation is required
please discuss with local Eaton representative.
5.4.7 Alarm Cancel
Alarm Cancel button is provided to allow a user to clear
or ‘cancel’ active alarms on the system. Please note
that once pressed there is no method of un-actioning an
Alarm Cancel.
Activating Alarm Cancel button will send a signal to
the 2Mx requesting a clear out of any currently active
alarms. If the activation input is still active, for example a
remote push-button connected into the IO-Tu, then the
alarm will immediately re-activate (although the audio
will pause for up to a second). The alarm cancel signal
self clears after ~ 200 milliseconds to prevent a broken
or stuck button from acting as an un-intended alarm
inhibit.
If assigned to a standard button the associated indictor
has the following states:
Off
Alarm Cancel is not active
Fast flashing (5 Hz)
Alarm Cancel is active on the system
Solid
Alarm Cancel is active locally but not on the
system
ote:
N
: As part of system design for un-attended access panels in pub-
lic spaces; consideration should be taken as to whether Alarm Cancel is
a protected function.
