Figure 10 - Zoned Alarm activation
Please refer to section 5.6 and the SAS manual for more
information on confi guration of Zoning.
4.3.3 Alarm Cancel
The 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 the alarm cancel button will send a signal to
the PA/GA system asking it to clear out the currently
active alarms on that system. 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 ~4
seconds to prevent a faulty button or something resting
on the button permanently activating it from preventing
future activation from another source.
The alarm cancel button can be disabled in confi guration
to prevent the access panel from sending the alarm
cancel signal, use this for access panels located in less
secure areas.
The LED shows the following status:
•
None – Alarm Cancel is NOT active on the system
•
Solid Orange – Alarm cancel is active on the system
and been activated from this access panel
•
Flashing Orange (~ 0.5 Hz) – Alarm cancel is active on
the system but was activated by a different source
4.3.4 Alarm Attenuate
Alarm attenuate is provided to reduce the volume of the
currently active alarm on the system to a lower, pre-set
volume. The volume is controlled by the PA/GA system
controller, see Sonix 2Mx Technical Manual for details.
The alarm attenuate feature is a toggle action, each
press on the button causes the system to invert the
state of alarm attenuate. There is a ~1 second dead time
after each button press, this is to allow the system to
properly change state and ensure that the audio output
is correctly controlled.
Pressing the alarm attenuate button while an alarm is
NOT active will cause the LEDs to fl ash for ~1 second
and then extinguish.
The LED shows the following status:
•
None – Alarm Attenuate is NOT active on the system
•
Solid Orange – Alarm attenuate is locally active and
waiting on the system activating alarm attenuate
•
Fast flashing Orange (~5 Hz) – System is changing
state of alarm attenuate (temporary state)
•
Flashing Orange (~0.5 Hz) – Alarm attenuate is active
on the system
The button can be disabled in confi guration, but the LED
will continue to function.
